Product Description

1.25g Mini GBIC Optical SFP Transceiver Module 20km

1.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 (MSA) and SFF-8472.
