Ingellen is one of Chinese fiber optic manufacturers providing complete ranges of fiber optic related products like fiber optic transceivers with extensive compatible brands, fiber optic passive or active components, media converters, fiber optic test equipments or tools and most important, various kinds of fiber optic cables, of course cable ties for cable managements. Today, I will mainly introduce the not eye-catching but very important cable management tools – cable ties.

A cable tie is a kind of fastening tool that used to bind or organize cables no matter fiber optic cables or other electronic cables or wires. The cable ties are usually made of very strong and durable materials including plastics and metal. Thus they can often be used for many purposes like binding fences or plants in the gardens, using miniature cables for decorations, or using the stainless cable ties for electrical purpose or binding or tying purpose.
Cable ties come in different types according to their material, sizes, or purposes. Different types are for different applications. With so many kinds of cable ties available in the current market, the most two important types for cable managements are:

Velcro Cable Tie
Velcro is known as magic tie, it is also a brand name of Velcro Company that produce the first commercially marked fabric hook-and-loop fastener. A Velcro cable or hoop-and-loop fastener consists of two lineal fabric strips which are attached to the opposing surfaces to be fastened. One of them is a tiny hooks and the other is a smaller loops. When the two components are pressed together, the hooks catch in the loops and the two pieces fasten or bind temporarily. You can hardly separate them apart without the help of a third part, a cutting tool.

A Velcro cable tie is with self-gripping design and lightweight features neat and secure, and is ideal to used for fasten and secure wire bundles and harness components quickly. Velcro calble ties are available in different colors including blue, black, gray, red and green. Ingellen Magic Velcro cable ties are in 20 x180, 20 x160 MM hook and loop. And can be used with most tandard tensioning/cutoff tools.

Nylon Cable Tie
The important material for Nylon cable ties is (Polyamide 6.6), Nylon is one of the most commonly used synthetic polymers that primary invited for industrial applications which is a kind of strong and elastic fibers. Nylon 6.6 is especially ideal for outdoor use because of its high strength and a wide temperature range. Ingellen, as one of China reliable nylon cable ties suppliers, provide large quantities of Nylon cable ties with nylon 6/6, meeting UL 94 V-2 flammability classification and military specification MS 3367, structure with teeth on both sides for enhance strength and is used in continuous or extended exposure to high temperatures up to 250°F. Now, strandard, 4 x150, 200, 250 MM Nylon cable ties in natural color are offered from Ingellen Technology.

Using cable ties is an advanced way to manage wires and cables indoor or outdoors. There are many cable ties wholesaler in the markets, Ingellen, among them is the good and reputable one, providing good quantities of Velcro Cable Tie and Nylon Cable Tie, as well as many other fiber cable management related products with factory prices and guaranteed qualities.

Optical splitter is used to split the fiber optic light into several parts at a certain ratio. Fiber optic splitters, which are also known as beam splitters and power splitters, are optical devices that allow a variety of visible beams of light to be manipulated, split and combined into other beams.

Fiber optic splitter typical parameter include input and output part cable length, splitting ratio, wavelength, the optical loss, isolation, PDL and with what kind of fiber optic connectors. Fiber splitters are usually with 0.9mm, 2mm or 3mm cables. Because of the differences between working wavelength, there are single window and dual window fiber optic splitters. Typical connectors installed on the fiber optic splitters are FC or SC type.

Fiber optic splitters are important passive components used in FTTX networks. Two kinds of fiber splitters are popular used, one is the traditional fused type fiber optic splitter (FBT coupler), which features competitive prices. The cable type accepted by fiber optic splitters can be single mode or multi mode. And Single window optic splitter is designed for a single wavelength with a narrow wavelength window. Dual wavelength optical splitters are designed for two wavelengths with a wide wavelength window for each. The other is PLC fiber optic splitter, which is compact size and suit for density applications. Single-mode PLC splitter (Planar Lightwave Circuit) is developed using silica glass waveguide circuits and aligned fiber optic pigtails, integrated inside a miniature package.

Both of them have its advantages to suit for different requirement. Fiber optic splitters can be terminated with different kinds of connectors, the main package could be box type or stainless tube type, one is usually used with 2mm or 3mm outer diameter cable, the other is usually used with 0.9mm outer diameter cables.

Compared with the traditional standard copper coaxial cables, fiber optic cabling is a brand new and advanced method used in modern telecommunication and data transmission networking applications.In fiber optic networking system, fiber optic cable and end equipment use light pulses to transmit data. Light resource, Fiber optic cable and optical transceiver play a leading role in the whole transmission process. Fiber optic cables are made up of transparent glass or plastic fibers which allow light to be guided from one end to the other with minimal loss. Fiber optic cabling has obvious advantages over copper cabling when it comes to transmission efficiency, capacity, material cost and even environmental friendliness. Here are the detailed top 7 advantages of fiber optic cabling versus copper cabling.

1. Great transmission capacity

Compared with traditional copper, working frequency of fiber optic is 8-9 orders of magnitude higher, which work a greater carring capacity. Fiber optic cable is capable of carrying far more data than copper. Besides, it can also carry the information for much more distances. For example, a fiber optic can easily transmit a signal as far as 80 km or more without the need for amplification.
2. More transmission efficiency
In comparison, fiber Optic cables can transmit far more information, and with a greater degree of fidelity. Fiber links offer over 1,000 times as much bandwidth over distances over 100 times further than copper. For example, downloading a 2 GB movie over a typical “Fast Ethernet” connection (100 Mbps) would take almost 22 minutes. While, downloading the same movie over GPON with fiber optic cabling, and it would only take about 2 minutes. By providing quicker access to volumes of data that will empower end-users to be more productive.
3. Energy saving and environmental friendly
The equipment used for a Gigabit Passive Optical Network (GPON) fiber optic implementation is typically about 50% more energy efficient than the traditional networking equipment found in a IDF/Telco closet. This reduction in energy consumption for the IT network also means there is a huge reduction in the amount of Greenhouse Gas emitted into the atmosphere.
4. Free of interference
Unlike electrical cables which conduct with electricity, fiber optic cables are glass-based carring light signals. This eliminates the need for grounding and makes them immune to any type of electrical interference – even lightning. Taking the advantages of resistance to interference and atmospheric conditions, outdoor fiber optic cables can be used outdoors and even in close proximity to electrical cables without concern.
5. More data secured
Except for interference-free, class fibers can also work well in roughing conditions. We know, copper cabling is sensitive to water and chemicals, class fiber optic cabling runs nearly no risk of being damaged by harsher elements. Fiber Optic cables can easily endure living environment that coaxial cable just cannot, such as being buried with soil, or in close proximity to chemicals. Besides, since it is also far more difficult to tap, fiber Optic cabling would offers extra security for the data being transmitted.
6. Easy handling and installation
Fiber optic cables are much smaller and lighter as compared to copper-based cables, which make it much easier to handle and require less time and effort to install. In addition, the carriers would never get shocked when the fiber optic cables are break as the electrical coaxial cables do. Since Fiber optic cabling transmits light and not electricity, the people handling it run no risk of injury from fire, sparking or electrocution.
7. Cost effective
With the development of fiber optic technology, fiber optic cable is no longer always thought to be too fragile or expensive to the deployed for general applications, by contract, it has becomes more easier to work with and install. With various cable metal material price rising on the present market, while optic fiber has declined and the manufacturing processes have also been improving, Which has created an important prerequisite for the quick development of optical fiber communication.

Fiber optic cabling is being deployed in buildings, campuses and offices to provide an efficient, high-speed broadband network for end users. Fiber optic network can transmit larger quantities of data with far less loss, is able to delivery signals over long distances, carries little risk of corrosion, is with great environmental features and virtually free from interference. That’s the concludes from Ingellen.com, among the worlds foremost providers of fiber optic cables, fiber cable management solutions and other fiber networking and equipment management solutions for both business and home utilizations.

What exactly LSZH Cable  is?
Low Smoke Zero Halogen cable can be called LSF (low smoke and fume), LSHF (low smoke halogen free), and LS0H (low smoke zero halogen). LSZH cable, which is short for Low smoke zero halogen cable, refer to using compounds in the cable jacking manufacturing process that are halogen free and flame retardant. This type of jacket material has excellent fire safety characteristics of low smoke, low toxicity and low corrosion. LSZH cable is widely used in applications where people are present in poorly ventilated or confined spaces, like airplanes, rail cars, or offshore marine platforms.

Features of LSZH cable:

Halogen Free
Materials that contain halogens emit potentially harmful gases like chlorine, fluorine and bromine when burned, that makes halogens the main concern for the wire and cable industry. Harmful gases emit by halogen material are extremely damaging to the human respiratory system and can even corroded nearby equipment. PVC wire and cable has a huge amount of halogens in it. However, Halogen free cables, like LSZH cables, is mad up of a compound called polypropylene, will not produce a toxic gases during combustion.
Low Smoke
As we know, smoke inhalation is the main cause of death related to fires. Smoke inhalation occurs when products of combustion are breath in during a fire. Damages to the body are by simple asphyxiation (lack of oxygen), chemical irritation, chemical asphyxiation or a combination of all these. Because LSZH cables are low-smoke, people can make a quicker and easier escape in the event of a fire. There is far less smoke to limit their ability to see and breathe, allowing them to get out with less trouble.
Easy Jacket Cracking
Although LSZH cables have some important benefits, there is a still a shortcoming – easy jacket creaking. A qualified LSZH cable must have a high percentage of filler material. This means that the jacket will likely be less chemical and water-resistant and have poorer mechanical and electrical properties than a non-LSZH cable jackets. This makes LSZH cable more likely to experience jacket cracking during installation. However, special lubricants used for them will avoid the damage.

Pros and Cons of LSZH cable:
Pros：
1. LSZH produces less smoke when burned which allows more escape chances.
2. Less damage and less corrosion damage is done to the respiratory and nearby equipment in the fire because of little or no halogen gas released.
3. The jacket of LSZH cable has a lower coefficient of friction making installation easier.
Cons：
1. SZH is more susceptible to jacket cracking. Special lubricants are needed to minimize damage during installation.
2. LSZH jacket has a high filler content, around 50% to provide the required flame and smoke performance, which would results in a lower mechanical, chemical resistance, water absorption and electrical properties than non LSZH compounds.
3. The current generation of LSZH cables has not yet established a proven history of long time performance.

What’s indoor fiber optic cable

As we know, optical fiber cable is a cable with one or more optical fibers inside which is designed to protect the optic fibers from environment hazards. According to its application environment, it usually contains two types: indoor fiber optic cable and outdoor fiber optic cable. Indoor fiber optic cable is a typical optic fiber cable for indoor application, a simple cable enclosed with a bundle of flexible fibrous polymer strength members like aramid like Twaron or Kevlar in a lightweight plastic cover. At the end of each cable, it usually terminated with a specialized fiber optic connector to make it easy to be connected or disconnected from transmitting and receiving equipment.

Types of indoor fiber optic cables:

Application:

Indoor fiber optic cables are required to be installed in buildings, in walls, between floors, between building for indoor communication transmission application. According to the mode of the optical fiber inside the cable, there are single mode indoor fiber optic cables and multimode indoor fiber optic cables. When it comes to the communication network distance, the single mode indoor fiber optic cables are installed between the buildings where the distance is more than 100 meters, while multimode indoor fiber optic cables are used shorter distance connections. Now we Ingellen.com supply single mode fiber optic cable and multimode fiber optic cable for indoor use with various structures including Multi Purpose Distribution Cable, Multi Purpose Break-out Cable, Indoor Ribbon Flat Optical Fiber Cable, Flat Twin Fiber Optic Cable, Access Fiber Optic Cable etc. for your varies applications.

fiber optic cable is a cable containing one or more optical fibers. The optical fibers are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed. Fiber optic cable has become a standard component in most contemporary cable infrastructures. There may be many times that you need to choose the right fiber optic cables from several types of cables for applications. Your choice will affect the level of fiber protection, ease of installation, splicing or termination, and, most importantly, cost.

There are two methods that will help you make wise decision when choosing the right fiber optic cables for use.

Choosing according to the right fiber optic cable sheath:

1.You’d better choose fiber Armored Cable when use cable directly buried outdoor. And choose black plastic outer sheath cable with two roots and more than two root.

2. Pay attention to the characters of flame retardant, poison and smoke when use cable within the building. Generally, use flame retardant and smoke type cable in the pipeline. And choose flame retardant, smokeless and non-toxic type in exposed environment.

3. Choosing distribution Cable in the apartment building vertical wiring.Breakout cables are used to Level wiring type.

4. The best choice to choose multimode optical cable when the transmission distance is less than 2 km. In the other sides, use single-mode optical cable when the transmission is more than 2 km.

Choosing according to the application environment:

1. Fiber optic cables linking devices such as computers, telephone systems, distribution panels and fiber splice organizers. Generally speaking, these fiber cables are the least expensive and cable construction is very simple, because the devices can protect the fiber cables from outside forces and mechanical dangers.

2. Fiber cables installed across a room, under a floor, between walls or above suspended ceilings. The fiber cables used here must meet fire and smoke codes set by National Fire Protection Association and National Electrical Code.

3. Direct-burial cables. These cables are laid into deep trenches or plowed into the ground. Extra protection again moisture and temperatures are demanded for this kind of environment. The outer jacket of these direct-burial cables provides these protections.

4. Intrabuilding cables are often constructed as breakout cables. This design eliminates the need for patch panels in terminal closets. The fiber cables can be divided into individual fibers for distribution.

All cables share some common characteristics. For example, they all include various plastic coatings to protect the fiber, from the buffer coating on the fiber itself to the outside jacket. All also include some strength members for pulling the cable without harming the fibers. Outdoor fiber optic cable has moisture protection, either a gel filling or a dry powder or tape. Direct-buried cables may have a layer of metal armor to prevent damage from rodents. It is advisable that you should customize your cable to make it suitable to your application when the quantity of fiber optic cables is large and also for the cost-effective reasons.

Fiber optic cable can be divided into two kinds according to their application environment, outdoor fiber optic cables and indoor fiber optic cables. Outdoor fiber optic cable is made to protect the optical fiber to operate safely in complicated outdoor environment while indoor fiber optic cable is usually installed in buildings, in walls, between floors, between building and constructions when accessing directly to fibers and aerial, including power transmission lines and lamp posts. The difference between outdoor fiber optic cables and indoor fiber optic cables can be as following:

From structure and function:

Fiber optic cable outdoor has high mechanical strength and can endure high temperature variations. Most outdoor fiber optic cables are loose buffer design, with the strengthen member in the middle of the whole cable, the loose tubes surround the central strength member. Inside the loose tube there is waterproof gel filled, whole cable materials used and gels inside cable between the different components (not only inside loose tube) will help make the whole cable resist of water.

Indoor fiber cables require less temperature and mechanical strength than outdoor cables. Since it is used indoor, this kind of fiber optic cables requires no-waterproof structure, so that it is with good flexibility and high bending performance. However, indoor fiber optic cable has fire safety concerns; such as fire retardant and emits a very low level of smoke if on fire. It also allows smaller bend radius for installation.

From exterior:

See from the appearance of two kinds of fiber optic cables. Outdoor optical fiber cable is basically a black PE jacket.

The cable sheath of indoor fiber optic cable is usually yellow or orange PVC material.

  From application:

Indoor fiber cables are usually based on tight buffer design so that they can be mounted both horizontally and vertically. The fiber count is usually 4, 6, 8, 12, 24, 32 etc.

Outdoor fiber cable has more applications than indoor fiber cable. They can be used from laying on ocean beds to connecting various cities or any two buildings on a campus.

Indoor/outdoor optic cables are usually used in Local Area Network (LAN) application so the same cable can be used both outdoor (the link between buildings) and indoor (inside the building).

Indoor/outdoor optic cables are usually used in Local Area Network (LAN) application so the same cable can be used both outdoor (the link between buildings) and indoor (inside the building).

Ingellen is one of Chinese renowned fiber optic manufacturers offers both kinds of Fiber Optic Cables include indoor fiber optic cables(Multi Purpose Distribution Cable, Multi Purpose Break-out Cable, Indoor Ribbon Flat Optical Fiber Cable, Flat Twin Fiber Optic Cable, strongAccess Fiber Optic Cable) and outdoor fiber optic cables(Outdoor Unitube Cable, Outdoor Stranded Loose Tube Cable, Self-Supporting Cable LSZH Cable, Stranded Loose Tube Non-armored Fiber Optic Cable, Relief Fiber Optic Cable0, Photoelectric Hybrid Cable, Non-Metallic Duct Direct Buried Fiber Optic Cable, Waterproof Optical Cable).

Filter WDM module is based on Thin Film Filter (TFF) technology. The Filter-Based WDM is extensively used in EDFA, Raman amplifiers, WDM networks and fiber optics instrumentation. The FWDM series is based on environmentally stable Thin Film Filters technology. The device combines or separates light at different wavelengths in a wide wavelength range. They offer very low insertion loss, low polarization dependence, high isolation and excellent environmental stability. Our Filter-Based WDM product family covers following wavelength windows commonly used in optical fiber systems: 1310/1550nm (for WDM or DWDM optical communications), 1480/1550nm (for high-power DWDM optical amplifier/EDFA), 1510/1550nm (for DWDM multi-channel optical networks) and 980/1550nm (for high performance DWDM optical amplifier/EDFA) and 1310/1490/1550nm (for PON/FTTX/test instrument).

The family of miniaturized WDM filters is designed for the fiber optics communication markets. The 45 degree filters are designed to separate various wavelengths of light at an angle of 90 degrees to each. The 45 degree filters are not 100% efficient. They reflect approximately 15% of the transmitted wavelengths. This unwanted energy can be substantially reduced or eliminated by inserting a second trim filter. The trim filters are designed to be used at 0 degrees.

Ingellen’s 1310/1490/1550 nm filter wavelength division multiplexers (WDMs) use interference filter technology to separate or combine optical signals.With wide bandwidth, low insertion loss, high isolation, low temperature dependent loss, and low polarization sensitivity, Ingellen’s filter WDMs are ideal for telecommunication and WDM network applications.

1310/1490/1550 WDM devices based on thin-film filter technology are design to address the specific requirements of the FTTP market. Strong coating and passive device packaging capabilities feature these WDMs with excellent optical performance, good reliability and ultra-compact size.
