Description

This Arista QDD-800G-2LR4 is an 800GBASE-2LR4 optical transceiver in the QSFP-DD form factor, built from two 400GBASE-LR4 halves. It suits data-centre and campus switch uplinks and interconnects that need 800G over duplex single-mode fibre, and it can also serve 2x 400G links.

The module has two duplex LC connectors and reaches up to 10km over G.652 single-mode fibre. It uses the 1271, 1291, 1311 and 1331 nm wavelengths. Transmit power is -2.7 to +5.1 dBm per lane and receive power is -9 to 5.1 dBm per lane. Maximum power consumption is 16W, drawn from the host switch port.

It fits Arista switch ports that support QSFP-DD 800G and complies with the QSFP-DD MSA and IEEE 802.3. Each 400GBASE-LR4 half should interoperate with 400GBASE-LR4 optics over duplex single-mode fibre. The OSFP equivalent is OSFP-800G-2LR4.
