25G SFP28 MMF is a transceiver module that supports a 25 Gigabits per second (Gbps) data rate over multi-mode fiber (MMF) using a specific SFP28 form factor. It is designed for high-speed connections, primarily for data centers, providing 25G Ethernet connectivity and serving as a building block for 100G networks.
SFP-25G-SR compatible SFP28 transceiver provides 25GBase-SR throughput up to 100m over multi-mode fiber (MMF) using a wavelength of 850nm via an LC connector.
25G SFP28 (Small Form-Factor Pluggable) portfolio offers customers a wide variety of high-density and low-power 25 Gigabit Ethernet connectivity options for data center and high-performance computing networks applications. The 25G Modules are based on SFP28 form factor.
