The FUJITSU E25GSFP28SR is an SFP28 transceiver module that is optimized for 25 Gigabit Ethernet applications over Multi-Mode Fiber (MMF). Designed to enhance the bandwidth and speed of next-generation networks, this module operates at an 850nm wavelength and supports data transmission rates up to 25Gbps. Its compact SFP28 form factor ensures high port density and compatibility with existing SFP+ ports, facilitating a smooth upgrade path to higher network speeds without the requirement for a complete overhaul of the current infrastructure. The E25GSFP28SR is well-suited for short-range applications, offering reliable, high-speed communications for distances up to 70 meters using OM3 fiber, and up to 100 meters using OM4 fiber. This makes it an ideal solution for data centers, enterprise networks, and high-performance computing environments where bandwidth-intensive applications are prevalent. Low power consumption, integrated digital diagnostics monitoring, and enhanced thermal performance make this module a cost-effective, reliable, and environmentally friendly choice for upgrading network performance.
