Coaxial cable, as a common example, has a wire conductor in the centre (D) a circumferential outer conductor (B) and an insulating medium called the dielectric (C) separating these two conductors.
The telecine, VTRs and some of the larger equipment are often placed in a central apparatus room or machine room and are interconnected through Cable trays or raised floor to the color suite by patch panels, Coaxial cables, Computer network and Multicore cables.
Coaxial cable is a type of electrical cable in which the combined neutral and earth core completely surrounds the live core(s) in system of concentric cylindrical shells.
Fiber media converters support many different data communication protocols including Ethernet, Fast Ethernet, Gigabit Ethernet, T1/E1/J1, DS3/E3, as well as multiple cabling types such as coax, twisted pair, multi-mode and single-mode fiber optics.
In WAN and LAN environments IDFs can hold devices of different types including backup systems (hard drives or other media as self-contained, or as RAIDs, CD-ROMs, etc.), networking (switches, hubs, routers), and connections (fiber optics, coaxial, category cables) and so on.

Although experimental broadcasting had begun in the 1930s and television stations had been commercially licensed beginning in 1941, it was not until 1946 that coaxial cable connections allowed stations to share the same program schedules.
Within a few years, multi-channel transmission (1932), microwave transmission (1934), coaxial cabling (1936), the entire radio systems for the liners Queen Mary and Queen Elizabeth (1936–39), the patenting of pulse code modulation (1938) all contributed to the hey-day of telephony’s development.
Assuming we connect New York with Los Angeles by means of an electronic telecommunication network that operates in strong transmission ranges, as well as with continental satellites, wave guides, bundled coaxial cable, and later also via laser beam fiber optics: the expenditure would be about the same as for a Moon landing, except that the benefits in term of by-products would be greater.
After World War II, he was instrumental in AT&T's L-3 coaxial cable carrier systems, then transferred to the Radio Research Department where he made advances in many millimeter-wave components.
