Description

This Arista twin-port 800G OSFP transceiver carries two independent 400GBASE-VSR4 links over parallel multimode fibre at 850nm. It suits short-reach data centre connections, including 800G switch-to-switch links, 800G-to-2x400G connections and high-density 400G fan-out from 800G OSFP ports.

The module uses 8 x 100G PAM4 electrical and optical lanes, with 4 fibre pairs on each of its two MPO-12 APC connectors. Reach is up to 50m on OM4 and 30m on OM3 multimode fibre with a 50.0 um core. Tx power is -4.6 to +4 dBm per lane and Rx power is -6.3 to +4 dBm per lane. The operating case temperature range is 0 to 70 C, and power consumption is up to 16 W for 800G client transceivers.

It fits OSFP ports on Arista 800G platforms and interoperates at the optical level with 2x 400G-VSR4 OSFP or QSFP-DD modules. The MPO-12 APC connectors have an angled end-face, so APC multimode cabling is required rather than UPC. The QSFP-DD equivalent is QDD-800G-2VSR4.

FAQs

Q: Does it work with MPO-12 UPC cabling?
A: No. This module uses MPO-12 APC connectors with an angled end-face. It is not compatible with the MPO-12 UPC connectors used for 100G-SR4 and 40G-SR4 links, so APC multimode cabling is required.

Q: Can it connect to a 400G QSFP-DD or OSFP module?
A: Yes. Each half of the module is a 400GBASE-VSR4 link and interoperates at the optical level with 400G-VSR4 OSFP or QSFP-DD modules. The QSFP-DD equivalent of this part is QDD-800G-2VSR4.

Q: Will it fit a QSFP-DD port?
A: No. It is an OSFP form factor module and cannot be inserted into a QSFP-DD port. It is intended for OSFP ports on Arista 800G platforms.

Q: How far can it reach?
A: Up to 50m on OM4 multimode fibre and up to 30m on OM3, using parallel fibre with a 50.0 um core.

Q: How much power does the module draw?
A: 800G client transceivers draw up to 16 W per port, so the 800G host port must support that power draw.
