PRODUCT DESCRIPTION
Transceivers are a high performance, cost effective module which have a single LC optics interface. They are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA) and Digital diagnostics functions are available via the 2-wire serial bus specified in SFF-8472. The receiver section uses a PIN receiver and the transmitter uses a 1310 nm FP laser, up to 21dB link budge ensure this module 1000Base-LX Ethernet 40km application.
The transceiver consists of three sections: a DFB laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements.
1.25Gbps SFP BIDI Optical Transceiver Module is small form factor pluggable module for bi-directional serial optical data communications such as STM-8, OC-24,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.
