Tutorial of 100GBASE-PSM4 QSFP28 Optical Module

As the data center area and data transmission rate is growing, people need a minimum distance of 500m transmission distance of 100G optical module solution, based on this, 100GBASE-PSM4 QSFP28 light module came into being, it is a Single-mode parallel optical module, can provide cost-effective long-distance optical interconnect solutions for 100G data center.100G PSM4 standardThe 100G PSM4 standard is a multi-source protocol (MSA) designed to deliver a low-cost solution that delivers four 25 Gbps wavelengths over a single-mode fiber in addition to the IEEE 100G Ethernet specification, specifically design for transmission distances of 500 m Of the network applications. Compared to IEEE 100GBASE-LR4 (transmission distance ≤ 10 km) and 100GBASE-SR4 (transmission distance ≤ 100 m), the 100G PSM4 standard meets the transmission distance requirements of multiple applications and saves deployment costs.100GBASE-PSM4 QSFP28 optical module100GBASE-PSM4 QSFP28 optical module in line with 100G PS..
