Telecommunication cables are manufactured in two types of copper and light and are used in both aerial and ground methods
They have a strong coating to withstand rain and sunlight. These cables are typically black in color and are less flexible and more brittle due to tough coatings.
They are gray in color and better in flexibility and can be used indoors
Types of Copper Telecommunication Cables:
Earth Field Jelly Cable (BFC)
Canal Field Cable (CFC)
Irrigation Channel Cable (CUC)
Surge Arrester Cable (SSC)
Simple Air Cable (AC)
Double Air Intake (DW)
Types of Optical Communication Cables
Channel Jelly Field Optical Cable (OCFC)
Earth Field Jelly Optical Cable (OBFC)
Optical Air Cable (OSSC)
Telecommunication cables are manufactured in a number of different pairs. The single-pair telephone wire is known as the Rangier wire, which is most commonly used to communicate (fortune) between ports on cruise terminals.
Two-pair telephone cables are mostly used to connect telephone sets to a telephone socket.
The division of telecommunication cable according to the number of couples is as follows
Two couples cable
Four couples cable
Six couples cable
Ten couples cable
Fifteen couples cable
Twenty couples cable
Twenty-five couples cable
Thirty-two couples cable
Fifty Couples Cable
One hundred couples cable
Two hundred couples cable
It is possible to identify the pairs of wires by their color as follows:
The color of the pair of wires consists of 2 main colors and 2 sub colors, respectively:
main colors :
By combining the primary and secondary colors, we can have two separated pairs that represent a pair.
