Genuine Cisco QSFP-40/100-SR4 100G/40G Dual-Rate SR4 QSFP28 MPO 100m 850nm MMF Transceiver Module (10-3318-01)
The Cisco QSFP-40/100-SR4 (PN: 10-3318-01) is a versatile, high-density QSFP28 optical transceiver designed for short-reach data center applications. This module uniquely supports both 40 Gigabit Ethernet (40GBASE-SR4) and 100 Gigabit Ethernet (100GBASE-SR4) standards, making it an ideal choice for flexible network upgrades.
It operates over 12-strand parallel multimode fiber (MMF) using an MPO/MTP-12 connector. Utilizing 850nm VCSEL technology, it delivers reliable performance up to 70 meters on OM3 fiber and 100 meters on OM4 fiber. As a genuine Cisco product, it ensures 100% compatibility with Cisco switches and routers, featuring hot-swappable capability and Digital Optical Monitoring (DOM) for real-time status tracking.
