Description

This 400GBASE-DR4 QSFP-DD transceiver is built for 400G data centre links over parallel single-mode fibre. It suits network teams connecting spine and leaf layers, or breaking a 400G port out to four 100G-DR links within a facility.

The module runs four parallel 100G lanes at 1310nm and reaches up to 500m over G.652 single-mode fibre through an MPO-12 APC connector. Transmit power is -2.9 to +4.0 dBm per lane and receive power is -5.9 to +4.0 dBm per lane. Maximum power consumption is 12 W, with an operating case temperature range of 0 to 70 C. It is hot swappable, so links can be added or serviced without taking the switch offline.

It fits QSFP-DD ports on Arista platforms and is optically interoperable with 4 x 100GBASE-DR optics and with the OSFP-400G-DR4 module over the same single-mode fibre type. Check Arista's Transceiver and Cable Guide to confirm platform support.
