Description

The Arista OSFP-800G-2FR4 is a dual-rate 800G OSFP transceiver from the Arista 800G optics range. It carries two 400GBASE-FR4 links over two duplex single-mode fibre pairs with dual LC connectors, reaching up to 2km. It suits data-centre, AI/HPC and leaf-spine deployments that need 2x 400G or 2x 200G connectivity from a single 800G OSFP port.

The module is an 800GBASE-2FR4 optic using wavelengths of 1271, 1291, 1311 and 1331 nm over SMF G.652 fibre. Transmit power is -3.3 to +3.5 dBm per lane and receive power is -7.3 to +3.5 dBm per lane. It runs as 2x 400GBASE-FR4 or 2x 200GBASE-FR4, and uses a pull-tab latch. No licence or subscription is required. It draws power from the host switch OSFP port, with 800G client optics drawing up to 16 W per port.

It interoperates with 2x 400G-FR4 OSFP or QSFP-DD optics and 2x 200G-FR4 QSFP modules without breakout cables. It is intended for OSFP ports on Arista 800G platforms such as the 7060X6, 7800R4 and 7280R4 OSFP models running EOS 4.29.2 or later. OSFP modules do not fit QSFP-DD ports, and the QSFP-DD equivalent is QDD-800G-2FR4.
