Description

This is a 40GBASE-XSR4 QSFP+ optical transceiver from the Arista 40G QSFP+ optics range. It is built for short-reach 40GbE links in data centres where the fibre plant is parallel OM3 or OM4 multi-mode and a longer reach than standard 40GBASE-SR4 is needed.

The module runs at 850 nm over parallel multi-mode fibre with a 50.0 um core, terminated with an MPO-12 UPC connector. Reach is up to 300m over OM3 and 400m over OM4, compared with 100m and 150m for 40GBASE-SR4. Per-lane transmit power is -7.5 to +1 dBm and receive power is -9.9 to +2.4 dBm. Maximum power consumption is 1.5 W, drawn from the host switch port, so no external power is needed. The module is hot swappable and rated for an operating case temperature of 0 to 70 C.

It fits Arista 40G QSFP+ ports and needs an MPO-12 UPC parallel multi-mode fibre run. Refer to Arista's Transceiver and Cable Guide for platform-specific support.

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

FAQs

Q: What fibre does this transceiver need?
A: It needs parallel multi-mode fibre terminated with MPO-12 UPC connectors. OM3 gives up to 300m and OM4 gives up to 400m.

Q: How does 40GBASE-XSR4 differ from 40GBASE-SR4?
A: Both use 850 nm over parallel multi-mode fibre with MPO-12. XSR4 extends the reach to 300m on OM3 and 400m on OM4, compared with 100m and 150m for SR4.

Q: Does it need external power?
A: No. It draws a maximum of 1.5 W from the host switch port.

Q: Which ports does it fit?
A: It fits Arista 40G QSFP+ ports. Check Arista's Transceiver and Cable Guide for platform-specific support.

Q: Does it need a licence?
A: No licence is associated with this transceiver. It plugs into a compatible QSFP+ port and operates as a 40GBASE-XSR4 link.
