PSM4 Optical Module Principle
The QSFP28 100G PSM4 converts parallel electrical input signals into parallel optical signals by a laser array and then transmits them in parallel on the MTP/MPO single-mode ribbon fiber. Defined by the 100G PSM4 MSA standard, the QSFP28 PSM4 takes a different transmission approach. For reaches up to 100-meter Short Reach 4-channel (SR4) multi-mode transceivers are used. PSM4s is the transceiver that enables single-mode fiber to become popular in. 100G QSFP28 PSM4 is a cost-efficient 100Gbps optical transceiver designed for short-reach data center links where parallel single-mode fiber infrastructure is available. It is most commonly used for spine-leaf connections, switch-to-switch links, a...
