Product Description

The INFSPXX1ML-XXXX series single mode transceivers is small form factor plug-gable module for bi-directional serial. Optical data communications such as Fast Ethernet and OC-3/STM-1, SONET/SDH It is with the 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 pre amplifier (IDP) mounted in an optical head erand a limiting post-amplifier IC.

The INFSPXX1ML-XXDI series are designed to be compliant with SFF-8472 SFP Multi-source Agreement (MSA) and Industry
