Description

This 800G OSFP transceiver carries two 400GBASE-VSR4 links in a single hot-swappable module. It operates at 850nm over parallel multimode fibre and is built for short-reach 800G data-centre links, including 800G ports that break out to two 400G VSR4 links. It belongs to Arista's 800G OSFP optics range.

The module uses dual MPO-12 APC connectors and works with 50.0um OM3 and OM4 multimode fibre. Maximum reach is 30m on OM3 and 50m on OM4. Per-lane transmit power is -4.6 to +4 dBm and receive power is -6.3 to +4 dBm. It measures 13.0 x 22.6 x 100.4 mm and has an operating case temperature of 0 to 70 C.

It is intended for OSFP ports on Arista 800G-capable platforms. APC polish is required on the MPO-12 connectors, so do not mix them with UPC connectors.

FAQs

Q: Which fibre does this transceiver need?
A: It needs MPO-12 APC parallel multimode fibre, OM3 or OM4 with a 50.0um core. Reach is 30m on OM3 and 50m on OM4.

Q: Can I connect it to UPC-terminated fibre?
A: No. The module uses APC polish, so use MPO-12 APC connectors and do not mix them with UPC connectors.

Q: What type of port does it fit?
A: It fits OSFP ports on Arista 800G-capable platforms. Check Arista's transceiver compatibility matrix for your specific switch model.

Q: Does it support breakout to 400G?
A: Yes. It carries two 400GBASE-VSR4 links, so an 800G port can connect to two 400G VSR4 links.

Q: What is the maximum reach?
A: The maximum reach is 50m on OM4 multimode fibre and 30m on OM3.
