Description

The QSFP-40G-UNIV is a 40G QSFP+ universal optical transceiver for Arista switches with QSFP+ ports. It runs over both duplex multi-mode and duplex single-mode fibre through a duplex LC connector, so a single optic type covers mixed fibre plants.

It is built for upgrading data-centre links from 10G to 40G over existing duplex OM3/OM4 multi-mode or single-mode fibre, without re-cabling to parallel MPO fibre. Reach is up to 150m over OM3/OM4 multi-mode fibre, with single-mode reach to 2km as per the SKU variant. Operation is in the 1310nm window (1270-1330nm), in the style of 40GBASE-LX4.

It works with Arista switches with QSFP+ ports and is grouped with the 100G-SWDM4 optic as a duplex multi-mode option in Arista's transceiver range.

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