 Description
 The SFP transceivers are high performance, cost effective modules supporting data rate of
 125Mbps/155Mbps 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.
