Coaxial Cable
Coaxial cable is an electrical cable consisting of an inner conductor or several un- insulated conductors tightly twisted together, often surrounded by an insulating spacer, surrounded by an outer cylindrical conducting shield (sheath), and usually surrounded by a final insulating layer (jacket). The term coaxial comes from the inner conductor and the outer shield sharing ("co-") the same axis. It is often used as a high-frequency transmission line to carry a high-frequency or broadband signal but may also be used for frequencies as low as audio frequency. The electromagnetic field carrying the signal exists (ideally) only in the space between the inner and outer conductors. The shielding reduces interference from external electromagnetic fields, although coax cable does radiate energy, shielding does somewhat reduce the possibility of a transmitting device causing undesired interference through transmission line leakage.
USES: Coaxial Cable is for use in the interconnection of data processing equipment, information systems, LAN's, CATV, CCTV, MATV, and two- way radio in compliance with the National Electric Code, NEC article 725 type CL2 or UL 1354 and UL 1478.
Connector
A device (or more precisely, a mating pair of devices, often a plug and a socket) for connecting together two wires, cables, allowing electricity or electron to flow but also allowing easy disconnection and reconnection when necessary.
Interconnect
A telecommunication circuit is defined as follows:
The complete path between two terminals over which one-way or two-way communications may be provided. See communications protocol.
An electronic path between two or more points, capable of providing a number of channels.
A number of conductors connected together for the purpose of carrying an electric current.
An electronic closed- loop path among two or more points used for signal transfer.
A number of electrical components, such as resistors, inductances, capacitors, transistors, and power sources connected together in one or more closed loops.
Terminal Block
Terminal Block - Disconnection Modules & Connection Modules. It provides simple and high quality connection of jumper wires and cables to all points on the telecommunications network without the need for soldering, screwing and stripping.
It also can be used for all area of cable connection in telephone and computer networks, from Main Distribution, frame to subscriber's set.
In distribution boxes for internal wiring
In distribution boxes for outdoor installation
At modular wall distribution frame
In cross connection cabinet
At main distribution frame for exchanges
The Disconnection Module consist of disconnectable IDC - contacts for breaking a connection. In addition to which, there is a selection of plugs, cords and plug-in Magazines for testing and over voltage / over current protection
The basic functional units are the contacts. Consisting contact slots with flexible contact tags arranged at 45° to the axis of the wire and the plastic clamping ribs.
By pressing in the wire with the insertion tool (Yak-22), the insulation is cut through and the wire pushed between the flexible contacts tags. By the displacement of the insulation and the contant torsional restoring force, two permanent, gas-tight contact points are created.
The clamping ribs tightly grip the wire on both sides of the contact point, so that the connection can not be broken by mechanical shocks. A connection is made through one contact on the jumper side (a) and one on the switching side (aı) of the disconnection module.
Distribution Box
Distribution Box - Mainly use to connect the truck cable and subscriber line in telephone network lines for branching various working site. MK-FOUR distribution box is designed to protect switching elements from external influence and unauthorized access. The inter capacity can be fixed with 10 pairs module, up to maximum 400 pairs. The outer box is made with ABS plastic and metal material.
