Description

This is a 400G OSFP bidirectional multimode transceiver from the Arista 400G OSFP optics range, built for short-reach data centre links over parallel multimode fibre. It uses an MPO-12 UPC connector and runs 400GBASE-BIDI (400GBASE-SR4.2), reaching 70m over OM3 or 100m over OM4.

The mode is software configurable. It can run as a 400G point-to-point link, break out to 4x 100GBASE-BIDI (100G-SRBD), or break out to 4x 100GBASE-SR1.2. It operates on wavelengths of 855 nm and 908 nm and draws 12 W maximum. Transmit power is -6 to +4 dBm per lane and receive power is -7.9 to +4 dBm per lane.

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

FAQs

Q: What fibre and reach does it support?
A: It runs over parallel OM3 or OM4 multimode fibre with an MPO-12 UPC connector. Maximum reach is 70m on OM3 and 100m on OM4.

Q: Can it break out to 100G links?
A: Yes. The mode is software configurable, so it can run a 400G point-to-point link, break out to 4x 100GBASE-BIDI (100G-SRBD), or break out to 4x 100GBASE-SR1.2.

Q: What does it work with?
A: It fits OSFP ports on Arista platforms. It interoperates optically with 400G-SR4.2, 4x 100GBASE-BIDI (100G-SRBD) and 4x 100GBASE-SR1.2 optics. Refer to Arista's Transceiver and Cable Guide for supported platforms.

Q: How much power does it draw?
A: It draws 12 W maximum, which is the power class for 400G OSFP BiDi modules.

Q: Is there a QSFP-DD version?
A: Yes. The QSFP-DD equivalent is QDD-400G-SRBD, which suits QSFP-DD ports rather than OSFP.
