The Cisco QSFP-100G-SR4-S (P/N: 10-3142-03) is a high-performance 100GBASE-SR4 QSFP28 optical transceiver designed for high-density data center switches and routers. It adopts parallel multi-mode fiber (MMF) technology utilizing four independent 25Gbps lanes at an 850 nm wavelength, delivering an aggregated 100Gbps throughput via NRZ modulation. Equipped with an industry-standard MPO-12 connector, it supports reliable transmission distances of up to 70 m over OM3 MMF or 100 m over OM4/OM5 MMF. Factory-calibrated and verified by Cisco, this S-Class transceiver provides a cost-effective, low-power 100G short-reach solution ideal for data center spine-leaf fabrics and enterprise aggregation network.
