The Cisco SFP-25G-SR-S module is designed to meet the increasing demand for higher network speeds and bandwidth within data centers and cloud computing environments. This 25GBASE-SR SFP module supports a short-range multimode fiber optic link up to 100 meters on OM4 fiber and up to 70 meters on OM3 fiber. It operates at a wavelength of 850nm, leveraging the high-bandwidth capabilities of multimode fiber to achieve high data rates over relatively short distances. The module is ideal for high-density applications that require 25 Gigabit Ethernet connections, offering a cost-effective solution for upgrading current infrastructure. It features Digital Optical Monitoring (DOM) support, allowing for real-time monitoring of the transceiver's optical performance, including temperature, optical power received, and laser bias current. This facilitates easy diagnostics and maintenance, enhancing network reliability and performance. The SFP-25G-SR-S module is designed for compatibility with Cisco's 25G switches, routers, and optical transport devices, ensuring a seamless integration into existing networks.
