Welcome To The 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.
"PSM4 is an interesting new standard as it provides an economic proving ground for emerging optical technologies such as LISEL and Silicon Photonics alongside traditional DFB technology" Dale Murray, Principle Analyst, Light Counting
