USIC Cable Plant Basics

specific place on a facility that allows access to a cable or pipe for the purpose of applying an active signal

an electronic device that boosts the strength of a cable signal; amplifiers can add noise or distortion to cable signals

an electronic device that converts low-powered trunk line signals into high-powered feeder line signals; bridging amplifiers are enclosed in aerial cases or in aboveground peds

a casing that encloses and protects a bridging amplifier installed on an aerial cable line

an aboveground enclosure that houses a bridging amplifier

digital systems and equipment that provide consumers voice services, high speed data services, video on demand services, and interactive delivery services.

the second part of the cable system, used to transport cable signals to streets and easements.

third part of cable system that is used to transport cable signals to industrial, commercial, and residential buildings.

the first part of the cable system that is used to transport cable signals over great distances before they are distributed to customers.

series of amplifiers in a distribution system in which the output of one amplifier feeds into the input of another amplifier; cascades maintain signal strength throughout the distribution system

the inner core of a coaxial cable that consists of a solid copper, copper clad steel, or copper clad aluminum wire.

a type of cable, which is the most common means for transmitting signals, that consists of a center conductor surrounded by an insulating material and an outer conductor.

an electrical ground used by more that one facility.

the insulation material, which is typically polyethylene, that separates the center conductor and the shield of a coaxial cable

a passive device, which is contained in a bridging amplifier, that transfers energy from trunk lines to feeder lines by means of induction

the direction of signals through the cable system from the headend  to customers

coaxial and fiver optic cable used in the distribution system that runs from bridging amplifiers to line extenders and subscriber taps in peds

an extra length of fiber optic cable that is looped on aerial cable lines and near fiber nodes; provide easy access to fiber optic lines and make splicing lines easier.

the point at which fiber optic trunk line terminate, that converts light energy used into electromagnetic energy used in coaxial lines

type of cable consisting of very small diameter glass fibers that transmit cable signals on beams of light with very low energy loss

fiber to the curb- fiber from headend to subscriber drop

fiber to the premises- fiber from the headend to security boxes

a passive device used in amplifiers to allow some frequencies to pass through, while reducing the strength of other frequencies; filter separates and direct signals on multiple paths

a small, metal device that provides a means to  ground the shield of a subscriber drop

the electronic control center that amplifies, converts, processes, and combines all signals transmitted in a cable system
