The FiberMania 25G SFP28 SR optical transceiver is a high-speed, short-reach module designed for modern data center and enterprise networks. Operating at an 850nm wavelength over laser-optimized multi-mode fiber, it supports data rates up to 25.78Gbps, delivering reliable, low-latency connectivity for 25G Ethernet applications.

With a transmission reach of up to 100 meters on OM4 fiber and 70 meters on OM3 fiber, this module is ideal for intra-data-center links such as switch-to-switch, switch-to-server, and top-of-rack connections. Its short-reach architecture provides a cost-effective solution without compromising performance, making it well-suited for high-density network environments.

Housed in a hot-pluggable SFP28 form factor with a duplex LC optical interface, the transceiver integrates seamlessly with existing network equipment, including backward-compatible SFP+ ports. Its low power consumption, stable signal integrity, and compliance with IEEE and MSA standards ensure a scalable and reliable 25G network deployment.
