Arista 10GBASE-ZR SFP+ Transceiver, 80 km Single-Mode LC

For very long 10GbE spans, the Arista 10GBASE-ZR SFP+ Transceiver, part number SFP-10G-ZR, offers an 80 km rating over single-mode fiber with a duplex LC connector. It runs at 10GbE in an SFP+ form factor.

Spans of this length connect distant sites or bypass optical transport equipment. They also demand discipline in planning. The 80 km figure is a rating, and real routes lose light to attenuation, splices and connectors, so the loss budget of your specific fiber decides whether the link works.

Short links are the common trap. High-power long-reach optics can overload a receiver on a short span, so check the manufacturer's documentation for attenuation guidance if the route is not close to the full distance.

The module uses a duplex LC connector, so standard single-mode patching applies. Check that your Arista switch accepts this module, and that the far end uses a matching one.

The SFP-10G-ZR is offered new, refurbished and used. New and refurbished modules carry 1 year or 3 years of warranty, and used modules carry 90 days. Send your quantity, span and platform for pricing.
