Description

The QDD-800G-2XDR4 is an 800G QSFP-DD optical transceiver from Arista's 800G QSFP-DD optics range, built for high-density data centre links over parallel single-mode fibre. It suits AI/ML and spine-leaf fabrics where 800G ports need to reach up to 2km.

It operates as 800GBASE-2XDR4, which can be used as 2x 400GBASE-XDR4 or 8x 100GBASE-FR lanes, so one port can break out to multiple lower-speed links. The optic uses two MPO-12 APC connectors at 1310nm over G.652 single-mode fibre, with a maximum reach of 2km. Transmit power is -2.4 to +4.0 dBm per lane and receive power is -6.4 to +4.5 dBm per lane. Maximum power consumption is 16 W, supplied by the host switch port. Operating case temperature is 0 to 70 C.

It fits QSFP-DD ports on Arista 800G-capable platforms. The matching OSFP variant is OSFP-800G-2XDR4. It can interoperate with 400GBASE-XDR4 and 100GBASE-FR lanes.
