The Extreme 25G-LR-SFP10KM is a transceiver module by Extreme Networks, featuring an SFP28 form factor. It supports transmission speeds of up to 25 Gbps over single-mode fiber using a duplex LC/UPC connector and operates at a wavelength of 1310 nm.

This transceiver supports distances up to 10 km on standard SMF cabling and includes Digital Optical Monitoring (DOM) functionality for real-time diagnostics. It complies with IEEE standards for Ethernet transport in data center or enterprise aggregation scenarios. Power type is via the host device through hot-pluggable interface; no external mounting hardware required. Port count depends on switch configuration supporting one SFP28 slot per unit installed.
