The perform required is similar to that of a distribution amplifier or digital sign reclocker. A passive splitter can be used to separate an optical sign, but every sign is significantly weaker after the cut up.

As increasingly more video and communications migrate from copper to fiber, there will be a need for an optical routing switcher. The optical routing switcher is a new concept for the video market, however it has been used for many years within the telecommunications business to route and control phone site visitors. There are purposes in fiber-optic communications the place a signal requires regeneration and replication.

A system called an optical repeater or distribution amplifier can be used to repeat or regenerate a weak optical signal. This is useful on lengthy fiber-optic runs where a fiber signal is reaching its limit, as a result of the repeater can be used to regenerate the signal for additional distribution. In a traditional system, there are multiple fiber-optic transmitters at each video source.

The use of mirrors does permit multiple wavelengths in both instructions. Most broadcast and audiovisual techniques right now have a video and audio routing switcher. The switcher offers the user the power to regulate the source and destination of a given video and audio signal.

The fiber-optic signals are then usually routed to a central location or node. At the central location, the fiber-optic signals are transformed again to analog video, audio and data.
