Description

This 400GBASE-XDR4 OSFP transceiver delivers 400G over parallel single-mode fibre for data centre leaf-spine links and 400G-to-4x100G breakout designs. It is a hot-swappable module that fits OSFP ports on Arista 400G platforms.

The module uses an MPO-12 APC connector and runs at 1310 nm over SMF G.652 with PAM4 signalling, reaching up to 2km. Transmit power is -2.4 to +4.0 dBm per lane and receive power is -6.4 to +4.5 dBm per lane. Maximum power draw is 12W from the host port, and the OSFP body measures 13.0 x 22.6 x 100.4 mm. It operates at a case temperature of 0 to 70 C. No licence or subscription is required.

The optic interoperates with 4x 100GBASE-FR optics over parallel SMF with MPO-12 APC, so one 400G port can be broken out to four 100G-FR links. Arista's Transceiver Guide lists the minimum EOS version for each platform. For QSFP-DD ports, the equivalent part is QDD-400G-XDR4.

Enquire with XS Network Tech for new or used pricing and availability.

FAQs

Q: Does this transceiver need a licence or subscription?
A: No. It requires no licence or subscription and is powered from the host OSFP port.

Q: What fibre and connector does it use?
A: It uses parallel single-mode fibre (SMF G.652) with an MPO-12 APC connector, with a reach of up to 2km.

Q: Can I break it out to 100G links?
A: Yes. It interoperates with 4x 100GBASE-FR optics over parallel SMF, so one 400G port can feed four 100G-FR links.

Q: What ports does it fit?
A: It fits OSFP ports on Arista 400G platforms. Check Arista's Transceiver Guide for the minimum EOS version on your platform. For QSFP-DD ports the equivalent part is QDD-400G-XDR4.

Q: How much power does it draw?
A: It draws a maximum of 12W from the host OSFP port. It has no separate power supply.
