The Gigalight 12G-SDI SFP+ video optical transceiver (GHP-3112G-L2CD) is a high performance and cost-effective module for duplex video transmission application over Single-Mode Fiber (SMF). It is designed to transmit/receive data rates from 50Mb/s to 11.88Gb/s specifically for robust performance in the presence of SDI pathological patterns including SMPTE 259M, SMPTE 344M, SMPTE 292M, SMPTE 424M, ST 2081 and ST 2082 serial rates. The transceiver module consists of three sections: a DFB laser, a PIN photodiode integrated with a Trans-Impedance pre-Amplifier (TIA) and transceiver IC with MCU control unit for DDM. All the Gigalight modules satisfy Class I laser safety requirements.
