Outdoor UTP FTP Cat3 Cat 3 Cable Price Of Telephone STP 2-pair 1 10 20 25 30 50 100 Pairs Copper Cat5e Good Specifications Cable

introduction :

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

Differentiation method:
1. Line-to-Line Differentiation
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 in the 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 the user 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.

Product style:
There are several types of products available at present:
· LSZH low smoke halogen-free type, has a certain flame retardant capacity, will burn later, releasing CO, but does not release halogen;
· LSHF-FR low smoke halogen-free flame retardant, non-flammable, less CO release, low smoke, no halogen release, less harmful;
· Cables made of FEP and PFA fluoroplastic resins.
