850nm 100m 25G SFP28 Transceiver Module
Cisco SFP-25G-SR-S Compatible 25G MMF 850nm 100m SFP28 SR Transceiver Module
This SFP-25G-SR-S Compatible 25G SFP28 SR transceiver is designed for use with Cisco 25 Gigabit Ethernet connectivity in data center and high-performance computing networks applications. It is programmed and tested to perform identical to original Cisco SFP-25G-SR-S 25GBASE-SR SFP28 Module and provide a cost-effective replacement. It can be used in 25 GE SFP28 ports of Cisco Fiber Switches, Routers, Line card, and so on. The SFP28 SR module support max links of 70m over OM3 or 100m over OM4 multi-mode fiber.
