Description

This Arista 800G OSFP transceiver carries two independent 400GBASE-LR4 links from a single 800G port over duplex single-mode fibre. It is suited to data-centre and HPC spine and leaf links, campus-interconnect runs up to 10km, and 800G-to-2x400G aggregation where high-density 400G connectivity is needed.

The module uses two duplex LC connectors and operates on the 1271, 1291, 1311 and 1331 nm wavelengths over G.652 single-mode fibre. Transmit power is -2.7 to +5.1 dBm per lane and receive power is -9 to +5.1 dBm per lane. Maximum power draw is 16 W, supplied by the host OSFP port, and no licence or subscription is required for the transceiver itself. Because it provides two distinct 400GE links without optical breakout cables, a 32-port 800G 1RU system can deliver 64 x 400GE ports.

It fits OSFP ports on Arista 800G platforms and interoperates at the far end with 400G-LR4 OSFP and QSFP-DD optics, including Arista QDD-800G-2LR4, as well as 200G-LR4 QSFP optics. Check Arista's Transceiver and Cable Guide for supported platforms and EOS versions.
