Description

This is a hot-swappable 400G QSFP-DD bidirectional multimode transceiver for short-reach data centre links. It runs over parallel MPO-12 UPC fibre using two wavelengths, about 855nm and 908nm, per fibre, and can be set in software to run as a 400GBASE-SR4.2 link or to break out into 4x 100GBASE-BIDI or 4x 100GBASE-SR1.2 links.

Reach is 70m over OM3 and 100m over OM4 multimode fibre. The module uses the QSFP-DD Type 1 form factor and draws a maximum of 12W from the host switch port. Per-lane transmit power is -6 to +4 dBm and receive power is -7.9 to +4 dBm. Operating case temperature is 0 to 70 C.

It fits QSFP-DD ports on Arista platforms and interoperates with 400G-SR4.2, 4x 100GBASE-BIDI (100G-SRBD) and 4x 100GBASE-SR1.2 optics. The OSFP equivalent is OSFP-400G-SRBD.
