The INSPL-35-BX/INSPL-53-BX series is small form factor pluggable module for Gigabit Ethernet 1000BASE-BX and Fiber Channel single fiber applications by using 1310nm / 1550nm transmitter and 1550nm / 1310nm receiver. The transmitter section uses a multiple quantum well A type / B type laser and is a class 1 laser compliant according to International Safety Standard IEC 60825. The receiver section uses an integrated B type / A type detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC. The INSPL-35-BX/INSPL-53-BX transceivers are compliant with SFF-8472 MSA.
