RSPD-03BD180-4955

1.25Gb/s 180km LC BiDi SFP Transceiver                                                      

Hot Pluggable, Single LC, +3.3V, 1490nm Tx/1550nm Rx, DFB-LD&APD, Single-mode, DDM



Description:

FIBERWDM RSPD-03BD180-4955 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 1490 nm DFB laser, more than 40dB link budge ensure this module 1000Base-ZX Ethernet 180km application.
