Brief Introduction to QSFP 100G PSM4 Optical Transceiver
2022年1月5日 · The 100G QSFP28 PSM4 is a high-speed, hot-pluggable and low-power-dissipation optical transceiver with a built-in digital diagnostics function. Defined by the 100G PSM4 MSA, the QSFP28 PSM4 takes a different transmission approach.
The QSFP-100G-PSM4-S module supports 100G link lengths of up to 500m over parallel G.652 SMF (Single-Mode Fiber). It accepts angle-polished MPO12 connectors and can interoperate with 4 individual 25G LR-S modules via a fiber breakout cable. PSM4-S complies with the PSM4 MSA and is primarily used in data center applications.

100G Optical Transceivers Links: PSM4 vs CWDM4 - Fiber Optic …
2017年2月1日 · The 100G PSM4 Specification defines requirements for a point-to-point 100 Gb/s link over eight single mode fibers (4 transmit and 4 receive) up to at least 500 m, each transmitting at 25Gbps. Four identical and independent lanes are used for …
2014年9月15日 · PSM4 uses four identical lanes per direction. The electrical connections from the module to the host can be done using standard specific designs. Examples would be CAUI-4 (four electrical lanes with a 10dB host channel). See Fibre Channel FC-PI-6p for operation at 28Gbps over four electrical lanes with a 15dB host channel. 2. References.
100G PSM4 MSA
PSM4 is a multi-vendor, multi-technology optical interface standard for 100Gbps optical interconnects. It utilizes a parallel single mode fiber infrastructure to support reaches of at least 500 meters. It allows for support by multiple electrical form factors, including QSFP, CFP, and embedded optical engines.
