Description

The OSFP-400G-LR8 is a 400GBASE-LR8 optical transceiver in the OSFP form factor, part of Arista's 400G OSFP optics range. It carries 400GbE over duplex single-mode fibre with LC connectors for reaches of up to 10km. It suits data centre and campus links such as inter-building, leaf-spine or DCI-style runs where 400G-LR4 optics are not used.

The module uses eight wavelengths around 1310nm (1274, 1278, 1282, 1287, 1296, 1300, 1305 and 1309 nm) over G.652 single-mode fibre. Transmit power is -2.8 to +5.3 dBm per lane and receive power is -9.1 to +5.3 dBm per lane. Maximum power consumption is 14W, drawn from the host switch OSFP port. It is hot swappable and needs no licence or subscription. Standard duplex LC connectivity means existing duplex single-mode fibre plant can be reused.

This module fits OSFP ports on Arista 400G switches. It is not interchangeable with QSFP-DD ports, where the QDD-400G-LR8 sibling module is used instead. It interoperates with other 400GBASE-LR8 optics. Check Arista's Transceiver and Cable Guide for per-platform support.
