It’s no mystery why fiber optic technology has grown in popularity since it was introduced in the 1970s. Sending data via infrared light pulses on a fiber line, rather than electrically over copper cable, allows the transmitting of more information faster, over longer distances and with no threat of electromagnetic interference. That’s why it is often the choice for systems that demand high bandwidth over long distances, as well as short distances with large bandwidth requirements such as data centers.
But not everybody understands the crucial step onto and off of the fiber optic superhighway – the fiber optic transceiver.
A fiber optic (or optical) transceiver serves as both a transmitter and a receiver. It is a small device that is plugged or embedded into another device within a data network. At the on ramp, it converts an electrical signal from a switch or router to an optical (light) signal. At the off ramp, it converts the optical signal back to an electrical signal.

We’ve all seen the equipment rack or IT closet that lacks cable management. Confusion reigns, as masses of wires run in all directions and every patch bay looks like a rat’s nest. You feel sorry for whoever must go in and install or re-route cables or troubleshoot wiring problems.
The good news is that wire routing is a universal challenge, so there are products to tame the cable confusion. In fact, there are hundreds of cable management items to choose from, so let’s simplify things. Most of them can be divided into three groups: rack and cabinet attachments, cable routers along walls and ceilings, and ties and straps for bundling.
Rack and Cabinet Attachments
A well-organized equipment rack or cabinet usually has a few attachments for ordered cable routing. We touch on a few of the most popular devices here.
A cable manager is a housing that mounts either inside or just outside of a rack to hold and direct cables. A horizontal manager mounts inside, taking up one or two RUs (rack units).
