Product Description

1.25G Transceiver SFP Module single mode 20km 1310nm 1550nm DDM compatible with Cisco


The SFP transceivers are high performance, cost effective modules supporting data rate of 1.25Gbps and 20km transmission distance with SMF.


The transceiver consists of three sections: a FP 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.
