Description

QSFP-100G-PSM4H transceiver is a parallel, single mode, 1310nm, 4-channel (PSM4), pluggable, QSFP28 optical transceiver designed for use in 100GbE Ethernet applications. It is also qualified for use in InfiniBand EDR end-to-end systems. This module incorporates state-of-the-art uncooled DFB laser and integrated circuit technology in order to provide high performance. The transceiver operates over 4-lane, parallel, single mode fiber (SMF) using a nominal wavelength of 1310nm, and is SFF-8665 compliant.

The transceiver has a standard QSFP28 connector on the electrical side towards the host system. The optical interface is composed of four optical channels/fibers in each direction and is intended for a parallel single-mode optical cable via a standard MPO connector. Each channel/fiber operates at signaling rates up to 25.78125GBd. Rigorous production testing ensures the best out-of-the-box installation experience, performance and durability.

The QSFP-100G-PSM4H 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 are controlled via control registers defined in the SFF-8636 standard.
