Product Description
The INFSPXX2GL-XXXX series single mode transceivers is small form factor pluggable module for bi-directional
serial optical data communications such as STM-16, OC-48,Fiber Channel, It is SFP 20-pin connector to allow
hot plug capability. This module is designed for single mode fiber and operates at a nominal wavelength of 1310nm (1550nm).
The transmitter section uses a multiple quantum well laser and is a class 1 laser compliant according to International Safety Standard IEC-60825. The receiver section uses an integrated InGaAs detector preamplifier (IDP) mounted in anoptical header and a limiting post-amplifier IC.
The INFSPXX2GL-XXDI series are designed to be compliant with SFF-8472 SFP Multi-source Agreement (MSA) and Industry working temperature.
