Description

Q56-200G-SR4H 200G SR4 InfiniBand transceiver is a 4-channel, pluggable, QSFP56, optical transceiver designed for use in 200Gb/s InfiniBand applications. This module incorporates integrated circuit technology in order to provide high performance. The transceiver operates over 4-lane parallel multi-mode fiber (MMF), using a nominal wavelength of 850nm, and is QSFP56 MSA compliant.

The transceiver has a standard SFF-8665 compliant QSFP56 connector on the electrical side towards the host system. The optical interface is composed of four optical channels/fibers in each direction, intended for a parallel multi-mode optical cable via a standard MPO-12 UPC connector. Each channel/fiber operates at signaling rates up to 26.5625GBd. Rigorous production testing ensures the best out-of-the-box installation experience, performance and durability.

The Q56-200G-SR4H transceiver has Digital Diagnostic Monitoring functions for supply voltage, temperature, laser bias current, optical transmit and receive levels with associated warning and alarm thresholds.The Q56-200G-SR4H transceiver will work with a fiber plant as specified in the QSFP MSA standard.
