Product Description
The Arista SFP-25G-SR is a high-performance 25 Gigabit Ethernet SFP28 (Small Form-factor Pluggable 28) optical transceiver module. It is specifically designed for short-reach applications within data centers, supporting the 25GBase-SR standard. This standard leverages 850nm VCSEL (Vertical Cavity Surface Emitting Laser) technology to provide efficient and reliable data transmission over multi-mode fiber (MMF) optic cables. This transceiver is optimized for connecting servers, switches, and other network devices at 25Gb/s speeds. It typically supports distances of up to 100 meters when used with OM4 multi-mode fiber, and shorter distances with OM3 fiber. The SFP28 form factor offers higher density compared to traditional SFP+ modules, allowing for more high-speed ports within the same physical space, which is crucial for modern, scalable data center architectures. Featuring a standard duplex LC connector, the SFP-25G-SR ensures easy integration with existing MMF infrastructure. Arista designs these modules for robust performance, low power consumption, and excellent thermal characteristics, ensuring reliability in demanding data center environments. The module supports hot-swappable installation, allowing for seamless upgrades and maintenance without network downtime.
