 Fiber Optic Cable in CATV & Broadcast
Cable television, originally known as Community Antenna Television(CATV), was introduced in the 1940s in areas that couldn’t receive the TV signal without obstruction.
The solution was to place an antenna on top of a large utility pole and locally share the signal. CATV was created when the signal from one master antenna was distributed over a large area using coaxial and amplifiers.
Today, CATV uses frequency-division multiplexing (FDM) to transmit up to 69 analog TV channels, each 4.5-MHz wide. Transmission is over coaxial cables arranged as a unidirectional tree, with wideband amplifiers used to compensate for the attenuation of the cable signal.

The number of TV channels is limited by the bandwidth of coaxial cables. The span of a CATV network is limited by the noise power, which increases as more amplifiers are added to compensate for the signal power loss during propagation.
Utilize optical fibers to transmit the TV signal
Fibers have a much lower attenuation than coaxial cables, so they can transmit signals over longer distance before it becomes necessary to use an amplifier.

Hybrid fiber/coaxial (HFC): The transmission over the fiber is still analog. The signal is fed into the coaxial cable network at various points, where the optical signal is converted into electrical signals.

The cost of each optical transmission line is spread over a few hundred users. Moreover, existing coaxial cables can be reused.

HFC cable distribution system has a longer span and better signal quality than a coaxial cable network. The network is now a tree whose first level is a fiber network and whose bottom levels are coaxial.

Fiber-to-the-curb (FTTC): Curb designates a location in some neighborhood where the fiber is connected to the local coaxial distribution network

From worldwide sporting events, to political coverage to the most glamorous award ceremonies - OCC is there. When the camera is live, the pressure is on to ensure every exciting shot transverse the globe to a TV screen. The fiber optic cable must repeatedly withstand the extreme demands of rapid deployment and retrieval applications.

The broadcast industry has established high standards in delivering major events and programs around the world. Specially designed fiber optic cable solves many complex applications because of the ruggedness and reliability of our cables and hardware products. Our stadium and arena cables are optimized to withstand the rigors of installation challenges such as difficult cable pulls, high tensile loading, and severe crush occurrences.
