Description

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.
