Description

The OSFP-400G-SRBD1 is a 400G OSFP multimode optical transceiver for short-reach data centre links. It uses an MPO-12 UPC connector and reaches 70m over OM3 or 100m over OM4 parallel multimode fibre, which makes it suited to top-of-rack and leaf-to-spine runs inside a facility.

This is a 400GBASE-BIDI (400GBASE-SR4.2) optic that uses two wavelengths, 855 nm and 908 nm, to carry 400G over a 12-fibre MPO connector, so existing parallel multimode cabling can be reused. It can be configured in software for a 400GBASE-SR4.2 point-to-point link, or broken out to 4x 100GBASE-BIDI (100G-SRBD) or 4x 100GBASE-SR1.2. Maximum power consumption is 12 W, and the module operates at a case temperature of 0 to 70 C.

It fits OSFP ports on Arista platforms and interoperates with 400G-SR4.2, 4x 100GBASE-BIDI and 4x 100GBASE-SR1.2 optics. The QSFP-DD sibling QDD-400G-SRBD1 uses the same optics.

FAQs

Q: What fibre and connector does it use?
A: It uses an MPO-12 UPC connector with parallel OM3 or OM4 multimode fibre. Reach is 70m over OM3 and 100m over OM4.

Q: Can it break out to 100G links?
A: Yes. It can be configured in software to break out to 4x 100GBASE-BIDI (100G-SRBD) or 4x 100GBASE-SR1.2.

Q: Which optics does it interoperate with?
A: It interoperates with 400G-SR4.2, 4x 100GBASE-BIDI (100G-SRBD) and 4x 100GBASE-SR1.2 optics. The QSFP-DD sibling QDD-400G-SRBD1 uses the same optics.

Q: What host port does it fit?
A: It fits OSFP ports on Arista platforms. Check Arista's Transceiver and Cable Guide for supported platforms and software versions.

Q: How much power does it draw?
A: Maximum power consumption is 12 W, drawn from the host OSFP port.
