SFP BIDI Transceiver,SM,Tx1490nm,155M,120km

Description
The SFP transceivers are high performance, cost effective modules supporting data rate of 125Mbps/155Mbps and 120km transmission distance with SMF.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.The transceivers are compatible with SFP Multi-Source Agreement and SFF-8472 digital diagnostics functions.
