SFP-25G-SL Overview
The Cisco SFP-25G-SL is a 25GBASE-SL SFP28 transceiver module designed for high-density 25Gbps optical interconnects over short-reach multimode fiber links in data centers.
This 25G SFP+ module provides 25Gbps connectivity over multimode fiber for distances up to 20 meters on OM3 fiber cables or up to 30 meters on OM4 fiber cables. The module supports short-reach links over standard 50um multimode fiber terminated with dual LC connectors.
The Cisco SFP-25G-SL module has a compact SFP28 form factor, low power consumption of 1.2W max, and commercial operating temperature range. It is compatible with Cisco switches and routers supporting 25G SFP28 ports.
