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!
