Description
MPS-C35-80LD/MPS-C53-80LDis a small form factor pluggable (SFP) Bi-Directional transceiver module for duplex optical data communications such as 100BASE-BX80 Fast Ethernet and 155Mbps SDH STM-1/SONET OC-3 LR-2. This BIDI SFP module provides 70km to 80km transmission distance over single strand of single mode fiber. Compared with commonly used dual fiber SFP modules, this bi-directional (BIDI) transceiver allows end users to reduce the total cost on fiber cabling infrastructure by requiring half of fiber cables, providing increased transmission capacity very convenient without installing new fibers.
The transmitter section uses a 1310nm ( or 1550nm) DFB laser that is a class 1 laser compliant according to International Safety Standard IEC 60825. The receiver section uses a high-speed 1550nm ( or 1310nm) InGaAs PIN photodiode (PD) integrated with a trans-impedance preamplifier (TIA). The module is fully compliant with SFP Multi-Sourcing Agreement (MSA) and SFF-8472. For further information, please see SFP MSA and SFF-8472 standard.
There are three versions of the series 155M SFP BIDI optical transceiver modules for different applications. The Standard grade (0~70ºC) is for commonly commercial application, the Extended grade (-10~85ºC) is for Extended temperature application, and the Industrial grade (-40~85ºC) is made with robust and reliable components to meet the needs of Industrial Ethernet application under harsh environmental conditions.
