Term
What are two types of interference for signals traveling along a wire.
Definition
Electormagnetic Interference
Radio Frequency Interference
Term
What is it called when a signal transmitted on one copper wire or pair of wires creates an undesired effect on another wire or pair of wires.
Definition
Crosstalk
Term
Cables that are installed inside walls or above drop ceilings where sprinkler systems cannot access in the case of a fire should be __________ or low smoke rated.
Definition
Plenum-rated
Term
__________ transmits light instead of electricity. The light (photons) is transmitted over glass and plastic.
Definition
Fiber-optic cable
Term
__________ is a cable with an optical fiber that is meant to carry a single ray of light: one ray of light, one mode. This type of cable is normally used for longer distance runs, generally 10 km, and up to 80 km.
Definition
Single-mode fiber optic (SMF)
Term
