A Guide to Understanding Signal Transport via Fiber

Fiber Hardware Equipment For Signal Routing And Distribution Can Satisfy Any Production Need And Size


Broadcast, sports and live event productions are getting bigger and more complex, requiring a multitude of signals to move video, audio and data back to the truck or studio. It is no wonder that fiber optic cables are the preferred medium to transport data due to their reliability and capacity to transmit high-resolution signals across long distances and at fast speeds, without the risk of degradation.

The technological advantages of fiber-based transport include reduced costs and labor effort, as well as benefits like routing video and audio signals together on a single fiber link. This versatility is made possible by hardware equipment designed for signal routing and distribution that can satisfy any production need and size.

These signal transport solutions are scalable connectivity devices for linking, transporting, distributing, and/or routing signals in a broadcast infrastructure. Here is a look at some common production requirements for transporting signal over fiber.

When there is a simple, single hop, 3G & HD SDI fiber optic run with a clean signal.

Recommendation:  MultiDyne SilverBULLET

An economical solution designed for high-quality transmission of SD, HD and 3G SDI signals on single mode fiber. The SilverBULLET can be used as a compact throwdown or mounted in the Bexel 1-RU (Rack Unit) tray when density is needed.

When there is a need for a quick deployment of video, audio, and intercom that performs reliably whether the units are hundreds or thousands of feet apart.

Recommendation: Studio Technologies Live-Link and Live-Link Jr.

A comprehensive fiber-optic-connected solution for transporting digital video, audio, intercom, and data between a remote camera location and a truck or control room.

When there are many signals to move over fiber, but not enough fiber strands available due to full cable trays or a lack of access.

Recommendation: MultiDyne FiberSaver Series

An innovative solution for combining as many as 18 HD–SDI feeds, or optical signals of any wavelength onto one single–mode fiber. Bexel offers FiberSavers in a multitude of sizes: 3×3, 4×2, 6×0, 6×6, and 9×9 configuration.

When there is a need to move a large amount of video over just a few fiber strands.

Recommendation: MultiDyne VF-9000

A 1-RU (Rack Unit), very high-density video fiber optic transport platform that offers 18 optical I/O.

When there is a need to transport audio and intercom to a number of locations around a venue.

Recommendation: Calrec Hydra2 / Focusrite RedNet / Lawo Dallis / Telecast Adder II

Provides seamless, scalable audio networking infrastructures which allow for large numbers of inputs and outputs to be shared and controlled regardless of location.

When there is a need for full connectivity to a set or announce booth.

Recommendation: Bexel Fiber Booth Kit / Bexel Mini Fiber Booth Kit

Economical, yet powerful packaged solution that provides interfaces for audio, video, intercom and IFB from the mobile unit. Bexel has a number of different booth kits to support different signal requirements and space available.

When there is a need to add RF Zones to an area but the cable runs are too far.

Recommendation: ViaLite RF-Over-Fiber packages

Distances of 300 feet or more generally require RF-over-fiber, which extends the range of the antennas that wireless cameras, microphones and production communications (in-ear monitors, intercoms, and IFBs) use. Fiber based antenna-remoting offers a number of advantages including higher performance signal transmission and longer link distances.


Outside broadcast applications such as sporting events, major race-car and horse racing events, reality television, award shows and red carpet telecasts benefit tremendously from having a high performance signal transmission infrastructure. Bexel offers a range of fiber optic solutions including scalable hardware equipment designed for signal routing and distribution.
