The Cisco SFP-25G-SR-S is a high-performance SFP28 transceiver module designed for 25 Gigabit Ethernet applications over multimode fiber (MMF). It operates at an 850 nm wavelength and supports data rates up to 25.78 Gbps. The module offers a maximum reach of 70 meters over OM3 fiber and up to 100 meters over OM4 fiber, making it ideal for short-range data center and enterprise network deployments. Featuring a duplex LC connector, it is hot-swappable and requires RS-FEC (Reed-Solomon Forward Error Correction) on the host ports for optimal performance. With a low power consumption of less than 1.0W, it ensures energy-efficient operation.
