New Look. Same FluxLight.
If you've shopped with us before, you'll notice we look a little different. We rebuilt our website to make it easier to find exactly what you need: the right part, the specs to confirm it works with your equipment, and a quick way to order it. We refreshed our logo along the way, but the company behind it hasn't changed.

Same FluxLight
We're the same company, in business since 2003, with the same team and the same products. When you call (888) 874-7574, you'll reach the same people you always have.
Your account came with us, too. Sign in with the same email and password to find your saved addresses and past orders. If you bookmarked a product page, the link still works.

Find parts faster
Pages load quicker, and search now shows matching products as you type. Click the magnifying glass at the top of any page and enter the OEM part number you're replacing, like SFP-10G-LR, or one of ours.
Prefer to browse? The Optical Transceivers menu sorts parts by speed, form factor and compatible brand, and the Cables menu by speed, cable type and brand. Filters on every product list narrow the results by reach, wavelength, connector, temperature range and more.
Two pages help you start in the right place:
- Shop by compatible brand lists every equipment brand we carry parts for, with a count of transceivers and cables for each.
- TAA Compliant Products gathers our TAA compliant parts in one place for government buyers.

Deeper technical detail
At launch, a small set of our transceivers have new data sheets. We’ll add more over time. Where a part has one, its product page shows the full specs: ratings, operating conditions, optical characteristics, digital diagnostics and pin assignments. A contents list takes you straight to the section you need, and the Downloads tab has the PDF.
Many product pages also have a Platform Support tab listing the switches, routers and firewalls the part works in.
