PSM4 100G QSFP28 Transceiver

Cisco QSFP-100G-PSM4-S 100G QSFP28 Transceiver 100GBASE PSM4


100G QSFP28 1310nm 2km


This 100GBASE PSM4 QSFP28 transceiver is compatible with Cisco networking equipment and equivalent to Cisco QSFP-100G-PSM4-S. It offers 4 independent transmit and receive channels, each capable of 25Gb/s operation for an aggregate data rate of 100Gb/s and supports 2km optical link over single-mode fiber. The QSFP28 PSM4 optical transceiver uses a 12 fiber MTP (MPO) connector on the optical interface and uses an MSA-compliant 38-pin edge type connector on the electrical interface.



• Functionally identical to Cisco QSFP-100G-PSM4-S
• Up to 26Gb/s data rate per channel
• QSFP28 MSA compliant
• Compliant to IEEE 802.3bm 100GBASE PSM4
• Up to 500m transmission over G.652 single mode fiber
• Single 3.3V power supply
• Maximum power consumption 3.5W
• Single MPO connector receptacle
