Saved my posterior

We were all ready to move into the new building and bring the switches online. I had all the equipment from my networking team BUT no transceiver for the fiber uplink! ACK! I ordered 3 of these (1 extra, jic) with the fastest shipping, based on a contractor's recommendation. They were here, in time, and have worked flawlessly ever since (almost 1 year now). Thanks!

Cables

They did not have the cable I wanted so they reached out and upgraded me at no cost. Excellent company to deal with.

We use these for all our server projects and are always of high quality. We use these all the time and we always get them from Fluxlight as they always ship quickly. Whenever we have a question Fluxlight always answers with clarity. We always get what we asked for.

331-5311-FL Dell Compatible (10GBase-SR) Optical Transceiver
Darren S.Verified Buyer

Works great, inexpensive!

This unit was purchased to replace one from a different, even cheaper, vendor, but the other one was not properly recognized by the Dell switch I wanted to use it in, despite the published spec. The FluxLight transceiver was properly identified by the Dell switch, and works flawlessly. Definitely worth the (small) extra cost!

Pleased it works with third-party networking equipment!

The GLC-SX-MMD worked like a charm for us! We were a little hesitant to go outside our usual Cisco comfort zone, but we were pleasantly surprised to see that it works identically just as FluxLight claimed. It's a less-expensive option which allows us to expand our network without sacrificing our budget or compromising our system. I can't recommend this enough!
