Arista 400G-XDR4 OSFP Transceiver, SN Connectors, 2 km Parallel Single-Mode

SN connectors define the Arista OSFP-400G-XDR4-S. The other listed details are an OSFP form factor, 400GbE, parallel single-mode fiber and a 2 km reach.

So the decision is about cabling. If your patch panels and cords are built for SN, order this part; if not, a module without that connector requirement avoids adapters. Whichever you pick, the module at the far end has to be the same type. Optics, patch cords and panels should be checked together, because a mismatch at any point in the chain stops the link. Tell us what your panels use and the distance you need to cover, and we will confirm whether this module fits. Ask for the matching module for the far end in the same request.

It is a single-port unit for OSFP cages. New, refurbished and used units can be requested. New and refurbished list 1 year or 3 years of warranty, and used lists 90 days.
