    Posted by on 07/02/2013

    Get great internet speed with the GLC-LH-SM. This is a great, affordable option. High quality product and excellent customer service. Installation and operation takes a bit of research, but worth it! Excellent little investment. This is a great transceiver.

  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

    Posted by on 06/12/2013

    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.

    I am always happy when I get a product and have no issues with this. This GLC-LH-SM transceiver was easy to find and a good price. The shipping was then fast and the service was good. Once we got this it was installed well and has good range. Everything has been great with this, and if it hadn't been, well it was warrantied and guaranteed.

optical transceiver

Fiber Optic Networking Solutions

Fiber optics is the backbone of telecommunications and data communications. Fiber optic technology, such as an SFP transceiver, enables the high speed transmission of voice, video, and data across service provider and enterprise networks.

The key component in any fiber optic network is the optical transceiver module. This transceiver module is the device responsible for transmitting and receiving data across the network. Optical transceivers, such as SFP transceivers, like our SFP-10G-LR, are typically installed in devices like routers or network interface cards.

FluxLight offers a wide range of optical transceiver modules, including: X2, XENPAK, XFP, GBIC, SFP transceivers and more. We invite you to search for the transceiver you need by form factor, brand or rate (i.e. 10G SFP). We offer transceivers that are compatible with top brands such as Cisco, HP, IBM, Extreme Networks, Linksys, Juniper, Nortel, Force10, D-link, and 3Com.

In addition to transceivers, we also sell fiber optic cables, direct attached cables, fiber jumpers, media converters, and accessories in our online store.

Our selection of fiber optic transceivers, cables (singlemode and multimode), and media converters will allow you to easily deploy switches, routers, access points, and controllers across your network.

If your network is in need of an upgrade, look no further than FluxLight. We have the products you need to set up and maintain nearly any type of fiber optic network. We offer low prices, free domestic shipping and a 30-day money back guarantee!
