Description
Overview
GAOTek SMF optical transceiver is a parallel single mode, 4-channel (PS M4), pluggable, QSFP 28, optical transceiver designed for use in 100 GbE Ethernet applications. This module incorporates a state-of-the-art uncooled DFB laser and integrated circuit technology, in order to provide high performance operation. The transceiver operates over 2 x 4-lane parallel single mode fiber (SMF), using a nominal wavelength of 1310 nm in compliance with the 100 G PSM4 MSA. The transceiver is SFF-8665 compliant, i.e. it has a standard QSFP 28 connector on the electrical side towards the host system, single 3.3 V supply, hot pluggable, and two-wire serial management interface. The transceiver has Digital Diagnostic Monitoring (DDM) functions for supply voltage, temperature, laser bias current, optical transmit and receive levels with associated warning and alarm thresholds.Adjustment of the Tx input equalizer, Rx output amplitude/emphasis, and (de)selection of retiming is controlled via registers defined in the SFF-8636 standard.
