QSFP-100G-FR Arista Compatible 100G QSFP28 FR 2km SMF Transceiver

Rated for 2km over single-mode fiber, the QSFP-100G-FR handles the distance band where 100G has to cross a campus but not a city. It runs 1310nm into a duplex LC, fills a QSFP28 port on Arista platforms, and identifies itself to the host as a native module at first insertion.

Tested & Proven: Every TenFour Optics part is coded, tested, and verified before shipment — see Tested & Proven.

FEC — read before installing: RS-FEC runs inside this module. Leave host FEC off or on auto — do not force RS-FEC on the switch port; enabling host FEC will bring the link down. The far end of the link must also be a single-lambda optic of the same type with onboard FEC.

Two kilometers is enough to join data halls, cross a campus core, or reach a carrier-neutral meet-me room over the single-mode already in the ground, and DDM/DOM reports the health of the span in real time. Compliance with the MSA is confirmed unit-by-unit on the bench. The GreenLights4Life® Limited Lifetime Replacement Warranty applies from the first day it carries traffic. In-stock items ship same or next business day.
