Description

The SFP transceivers are high performance, cost effective modules supporting data rate of

1.25Gbps and 550m transmission distance with MMF.

The transceiver consists of three sections: a VSCEL 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.
