Cisco - SFP28 transceiver module - 10GbE, 25GbE (SFP-10/25G-LR-S)

BRAND NEW WITH FULL CISCO WARRANTY!!! Overview SFP-10/25G-LR-S is a Cisco 10/25GBASE-LR SFP28 transceiver module engineered for high-speed enterprise and data center network connectivity. The dual-rate optical module supports both 10GbE and 25GbE operation over standard G.652 single-mode fiber, providing connectivity distances of up to 10 km. Cisco identifies the module for SFP28-capable networking platforms and applications requiring high-density, long-reach optical connectivity. The module operates at a 1310 nm wavelength and uses single-mode fiber for long-distance Ethernet links. At 25GbE, the module requires RS-FEC on the host port for operation. Its SFP28 form factor is suited to high-density switch environments, including data center, enterprise core/distribution, and high-performance networking deployments.
