Great Modules!

I've been using these for years without issue. They cost a fraction of the price of the Cisco branded modules and accomplish the same thing.

Palo Alto PAN-SFP-PLUS-LR Compatible 10GBase-LR SFP+ 1310nm 10km DOM Duplex LC SMF Optical Transceiver Module

Roland L.Verified Buyer4/13/24

Working perfectly

The original Fluxlight QSFP-100G-SR4-A-FL had a stability issue which was corrected by a firmware update. Fluxlight Support was on the ball and resolved the issue quickly. The updated QSFP-100G-SR4-A-FL transceivers are now 100% rock solid in performance. As always, Fluxlight transceivers offer great value.

KenVerified Buyer2/15/24

Awesome company with really good optics

These optics work great and at a very reasonable price. We used to buy Cisco brand optics but after finding these, testing for a couple of years, we have standardized with Fluxlight optics and have saved thousands of dollars. The company is responsive for quoting and almost always has them in stock and ready to ship.

Good optics at good prices from a good company

We have used these optics for years, thousands of optics, and have only had a handful of failures (well less than 1%). They offer significant discounts and prices that are already a tremendous savings compared to Cisco.

Work great…priced right

We’ve been using Fluxlight products for years with 100% success. Our recent upgrade to 10G networking continues that trend using both fiber and Ethernet transceivers.

ChrisVerified Buyer2/2/24

FluxLight is my Go-To

I cannot recommend this company more. For the last five years, we have had chaotic deployments popping up out of nowhere, and FluxLight has been there to support us when we need things done yesterday. Having them local to us is a Godsend, as well as their shipping to our other facilities all across the world. The service is fast, the people are friendly, and the competitive pricing is the cherry on top.
