Product Description
The Arista OSFP-400G-SR8 is a state-of-the-art transceiver module designed to deliver an aggregate bandwidth of 400Gb/s. It utilizes the OSFP (Octal Small Form-factor Pluggable) form factor, which is engineered to support higher power consumption and thermal dissipation requirements for next-generation high-speed networking. Adhering to the 400GBase-SR8 standard, this module employs 16 parallel optical lanes – eight for transmitting and eight for receiving – each operating at 25Gb/s. This parallel architecture requires a specialized MPO-16 connector, which accommodates the 16 fibers necessary for this configuration. The 850nm wavelength is used for short-reach communication over multi-mode fiber. Designed for short-reach applications within data centers, the OSFP-400G-SR8 can achieve distances of up to 100 meters using OM4 multi-mode fiber. Its higher port density and bandwidth capabilities make it an essential component for modern hyperscale data centers, cloud infrastructure, and high-performance computing environments where massive data throughput is critical.
