Description

The Arista OSFP-400G-SR8 is a 400GBASE-SR8 OSFP optical transceiver for short-reach 400GbE links in the data centre, such as leaf-spine and top-of-rack or row interconnects. It is built for Arista OSFP-capable switches and runs over parallel multimode fibre.

It uses eight parallel lanes at 850nm with an MPO-16 APC connector. Reach is up to 100m over OM4 multimode fibre and 70m over OM3. Transmit power is -6.5 to +4.0 dBm per lane and receive power is -8.4 to +4.0 dBm per lane. Maximum power consumption is 12W, drawn from the host OSFP port, and the operating case temperature range is 0 to 70C.

The module meets IEEE 802.3 Ethernet and OSFP MSA standards and fits Arista OSFP ports. It requires MPO-16 APC parallel multimode cabling (OM3 or OM4).
