Another great purchase from Fluxlight! We keep this item in all our warehouses.
Solid product and worked as advertised in our N520 and Cisco 3850 switches. No issues with recognizing the device in either switch.
Once again we can rely on Fluxlight for a Cisco Compatible optical transceiver. Another good purchase at a good price.
Once again another great Cisco Compatible item. Always can trust Fluxlights items. Will keep buying.
Was exactly what we needed, perfect customer service and very quick ship, highly recommend.
Installed the items in some dated 3560 switches. They came right up and worked perfectly.
Great service!!
I really like that this site lets me choose the distance on my GLC-BX-D. I don't need something that gives me 120km range, for my small project, the 10km was fine, and that's all I wanted to pay for. But it was a nice surprise to see Fluxlight has the GLC-BX-D in so many range choices. I know now that for future project I can buy just what I need. I had no problems installing it, and there haven't really been any hiccups in its use either.
The GLC-BX-D is a great transceiver for a small business conserving fiber. You get full-duplex GigabitE over a single fiber up to 10 km. Now we can double our links without installing more fiber!
I love the GLC-BX-D, let me just say. It supports DOM, which makes it easy to see the state of the transceiver after its installed. That makes troubleshooting the device after it's installed much, much easier. The bidirectional, single fiber connection is also pretty versatile. You won't find too many network devices that can't interface with the GLC-BX-D.
