  1. Dependable Product for a Great Price - How often does that happen? 5 Star Review

    Posted by on 02/23/2015

    We have been doing business with FluxLight for several years and have been very satisfied with their products and their prices. When I am in need of another SFP pair, media converter, or fiber patch, I never think of looking anywhere else. I know from experience that I will receive a dependable product for a great price. I should also mention the prompt service and delivery.

  2. Great Product/Better Price 5 Star Review

    We started using BX SFP Modules some years ago. The intial benifit was doubling our existing fiber runs by using only one for TX/RX. Fluxlight is always willing to work with you to make sure you have the correct product for your application. Pricing is a great point of theirs also. Highly recommend this company.

  3. Exceeded Our Expectations! 5 Star Review

    Posted by on 10/10/2013

    Our backs were against the wall on a project, and our normal supplier, which only carried "Cisco-priced" models of the SFP pairs we needed, was out of stock and wasn't going to get restocked for 2 weeks! Fortunately, Daniel and team had what we needed, and for a significant savings. We ordered 1 pair of SFPs, hoping they would work. We have since ordered more, and plan to order more things from FluxLight in the future.
    Thanks for being there for us! - Dave

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!
