The Cisco SFP-10/25G-LR-I is a hot-swappable transceiver module from Cisco in the SFP28 form factor. It supports transmission speeds of 25 Gbps and 50 Gbps over single-mode fiber using a wavelength of 1310 nm, with dual LC/PC connectors for up to 10 km reach.

This transceiver operates on SMF cabling and uses long-range (LR) optics suitable for extended links between switches or routers within data centers or enterprise backbones. The unit connects via duplex LC interfaces and complies with IEEE standards where applicable. Its industrial temperature range variant allows deployment in environments requiring durability beyond standard commercial specifications. Power type depends on host system integration; cooling is typically passive through chassis airflow based on switch design constraints.
