Order online and went very smooth and received the item in excellent time.
We have used these for years with zero failures with no compatibility issues. The pricing can't be beat!
Another great product we purchase from Fluxlight. Might as well be the same as buying from Cisco but better customer service.
We purchased this SFP and has worked like a champ. No hickups, solidly built and compatible with our Cisco switches.

These work for us every time. Good products with good pricing.
I have been doing business with Fluxlight for the last 12 years, best customer service great product and great price 😊 what can I say, they are the best.
We use these transceivers in our schools and are very pleased with their performance and reliability. We've had no issues and highly recommend them!
I've been using FluxLight for several years for my fiber-related needs. Their products are every bit as reliable as "name brand" devices costing many times as much. Their customer service is way above average as well providing an always accurate assessment of my needs and fast shipping at fair prices. More than once they've gotten me out of a tight spot. I enthusiastically recommend them.
