Description

This 400GBASE-VSR4 OSFP transceiver provides 400G Ethernet over parallel multi-mode fibre for short-reach links inside the data centre. It suits leaf-spine connectivity and intra-rack or adjacent-rack runs where 50m on OM4 is enough, and it fits OSFP ports on Arista platforms.

It uses an MPO-12 APC connector at 850nm over parallel OM3 or OM4 multi-mode fibre, with a reach of 30m on OM3 and 50m on OM4. Maximum power consumption is 12W, drawn from the host OSFP port. Transmit power is +4.0 to -4.6 dBm per lane and receive power is +4.0 to -6.3 dBm per lane. The module is rated for an operating case temperature of 0 to 70 C.

It complies with IEEE 802.3 and the OSFP MSA. Some modules are supported only on specific Arista platforms, so check the Arista Transceiver and Cable Guide for your switch. The QDD-400G-VSR4 is the QSFP-DD counterpart for QSFP-DD ports.

FAQs

Q: What fibre and reach does this transceiver support?
A: It runs over parallel OM3 or OM4 multi-mode fibre with MPO-12 APC connectors. Reach is up to 30m on OM3 and up to 50m on OM4.

Q: Which ports does it fit?
A: It fits OSFP ports on Arista platforms. Some modules are supported only on specific platforms, so check Arista's Transceiver and Cable Guide for the supported list.

Q: Is there a QSFP-DD version of this optic?
A: Yes. The QDD-400G-VSR4 is the QSFP-DD counterpart for QSFP-DD ports.

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

Q: Does it need a licence or subscription?
A: No. It is a passive optical module and is powered by the host OSFP port.
