Product Description

CAT3 TELEPHONE CABLE MULTI PAIRS

Because there are so many wires and the color is fixed in some colors, it is not easy to distinguish the corresponding sequence of all cables without mastering the skills.

Here's how to distinguish the order of cables:

Basic color :
A : White, red, black, yellow and purple
B : Blue, orange, green, brown and grey

Differentiation method :
1. Line-to-Line Differentiation
Each pair of lines consists of a and B colors. For example, line 1-5 pairs of A-color white and B-color white are formed respectively. By analogy, 25 pairs can be formed, which is a basic unit.

2. Distinguishing method of bandage
The basic units are tied up in different colors to distinguish the order. The bandage color is also composed of basic colors inthe same order as the line pairs. If: white and blue bandage is the first group, line number 1-25; white orange bandage is the second group, line number 26-50, and so on.

Transmission distance :
The cable with 0.4mm diameter has a loss of 1.64dB per kilometer and a ring resistance of 296. If the maximum attenuation of theuser line is 7.0dB, the length of the cable with 0.4mm diameter can reach 4.26Km at attenuation of 7.0dB.

 

If the ring resistance of the subscriber line is less than 1700, the maximum communication distance of the cable with 0.4mm diameter is 5.74Km, but the attenuation is 9.42dB. The maximum transmission distance is not more than 3Km if the loop resistance of the subscriber line is less than 900 ohms when the ADSL service is opened.

 

Large logarithm cables are generally divided into three kinds of large logarithms and five kinds of large logarithms, which can be divided into five pairs of 10 pairs, 25 pairs of 30 pairs, 50 pairs, 200 pairs of 300 pairs.

Generally speaking, large logarithmic cables are commonly used as voice backbone in weak current engineering.

Application :
Large logarithmic cable products are mainly used in vertical trunk system. The selection of cable category should be based on therequirement of transmission frequency and distance of integrated wiring system in engineering, and select cable category (3, 5, 6 copper core twisted pair cables or optical cables).
