    Works as it should. Installed in a Cisco 3750 and a 3560 both worked great.

  6. Great Optical Quality with GLC-LH-SM 5 Star Review

    Posted by on 08/02/2013

    The GLC-LH-SM has been a good improvement for our network. Rated for 10km but we got a 15km link up and running steady with zero bit errors with this Fluxlight part!

  7. Easy to Install GLC-LH-SM 5 Star Review

    Posted by on 08/02/2013

    I'm more than pleased with this GLC-LH-SM. It was very easy to install. The old module gave us some trouble coming out of the port, so we were worried that the new one might not fit properly. It went in smoothly, though. It works really well, too, with great range for the protocol.

  8. GLC-LH-SM is a Huge Upgrade 5 Star Review

    Posted by on 07/26/2013

    The GLC-LH-SM is a great transceiver for any situation! I upgraded recently upgraded from my GBIC and what a huge difference. Definitely much faster, more effective performance. Overall, my network works beautifully with these products. Grateful to Fluxlight for their good finds!

  9. Single Mode GLC-LH-SM Does the Trick 5 Star Review

    Posted by on 07/09/2013

    I've really gotten a lot of use out of the GLC-LH-SM. It's a single mode device, so it's compatible with a lot of different services. I like that it interfaces with most other name brands too. FluxLight wasn't a brand I was aware of until I used the GLC-LH-SM, but it works really well.

  10. Got What I Wanted with GLC-LH-SM 5 Star Review

    Posted by on 07/03/2013

    The GLC-LH-SM is an efficient little transceiver. It's one of my favorites for building new PCs. That's because it has a great balance between usability and price. Especially here, the GLC-LH-SM is a really cost-effective solution. Good networking starts with the GLC-LH-SM in my opinion.
