  2. High Powered Ethernet with GLC-LH-SM 5 Star Review

    Posted by on 06/12/2013

    The GLC-LH-SM will enable a blazing fast Ethernet connection on your computer. It requires a little bit of know-how to install, but once you figure it out you're good to go for life. I can usually coax up to 1 gbps out of this baby, which is really good for my machine. Not a bad little transceiver.

  3. Reliable Connection with GLC-LH-SM 5 Star Review

    The GLC-LH-SM is one of my favorite transceivers, mostly because of its price. It's made by Cisco, so you know you can trust the quality of its parts, and it's compatible with lots of different devices. It was relatively easy to install. For the price, you can't do much better than the GLC-LH-SM.

  4. Yes, That's the Real GLC-LH-SM Price 5 Star Review

    Posted by on 06/11/2013

    I couldn't believe my eyes when I saw this GLC-LH-SM transceiver was only $50. Granted, it's an off-brand, but it works with Cisco gear and other good brands, so what's the difference? I found it to be a simple to use transceiver for my system. It's not the best out there, but it's certainly the best for its price.
