Communications have become an essential component of modern society, and the cables that transmit data are crucial in ensuring efficient communication. The importance of通信电缆的颜色 cannot be overstated, as it helps in identifying the type of cable and its purpose. This article will provide a comprehensive guide to cable colors, their corresponding prices, and their uses in telecommunications.
Cable Colors and Their Prices
1、Black Cables
Black cables are used for transmitting power and signal in underground cable systems. They are typically made from PVC or PE materials and are available in different sizes and lengths. The price of black cables varies depending on the length, material, and brand. A typical price range for a 100m black cable is around USD 2-5 per meter.
2、White Cables
White cables are used for twisted-pair cables, which are commonly used in Ethernet networks. They consist of four wires twisted together and insulated with a plastic coating. White cables are available in various standards, such as UTP (Unshielded Twisted Pair), STP (Shielded Twisted Pair), and F/UTP (Fiber Optic Unshielded Twisted Pair). The price of white cables varies depending on the standard, length, and brand. A typical price range for a 100m UTP white cable is around USD 0.5-1 per meter.
3、Blue Cables
Blue cables are used for coaxial cable television (CATV) systems, which transmit video signals through copper wires wrapped in insulation surrounded by polyurethane or another material. Blue cables are available in different grades, such as Class A, B, C, and D, which indicate the quality and performance of the cable. The price of blue cables varies depending on the grade, length, and brand. A typical price range for a 100m Class A blue cable is around USD 2-3 per meter.
4、Yellow Cables
Yellow cables are used for optical fiber communication systems, which transmit data through light waves transmitted through glass or plastic fibers. Yellow cables can be single-mode or multi-mode, with single-mode cables having a smaller core size and higher bandwidth than multi-mode cables. The price of yellow cables ranges depending on the type (single-mode or multi-mode), length, and brand. A typical price range for a 100m single-mode yellow cable is around USD 50-100 per meter.
5、Red Cables
Red cables are used for power distribution in electrical grids and telecommunication infrastructure. They carry high voltage and are typically made from copper or aluminum wires coated with an insulating material. The price of red cables varies depending on the length, material, and brand. A typical price range for a 100m red cable is around USD 1-3 per meter.
6、Green Cables
Green cables are used in satellite communications systems, which transmit signals through orbiting satellites. They consist of two wires, one for transmit and one for receive signals, and are typically made from polyethylene or other durable materials. The price of green cables varies depending on the length, material, and brand. A typical price range for a 100m green cable is around USD 5-10 per meter.
Cable Applications and Prices
1、Power Cables (black)
Power cables are used to supply electricity to homes, businesses, and industrial facilities. They can be classified based on their voltage level (AC or DC) and wire gauge (thickness). The prices of power cables vary depending on the type, voltage level, wire gauge, length, and brand. A typical price range for a 100m AC black power cable is around USD 2-5 per meter.
2、Ethernet Cables (white)
Ethernet cables are used in computer networks to transmit data between devices using twisted pair wires. They can be classified based on their standard (Twisted Pair, F/UTP, STP, etc.). The prices of Ethernet cables vary depending on their standard, length, and brand. A typical price range for a 100m UTP white Ethernet cable is around USD 0.5-1 per meter.
3、CATV Cables (blue)
CATV cables are used to transmit video signals through copper wires wrapped in insulation surrounded by polyurethane or another material. They can be classified based on their grade (Class A, B, C, D). The prices of CATV cables vary depending on their grade, length, and brand. A typical price range for a 100m Class A blue CATV cable is around USD 2-3 per meter.
4、Fiber Optic Cables (yellow)
Fiber optic cables are used for long-distance communication applications due to their high bandwidth and low latency. They can be classified based on their type (single-mode or multi-mode). The prices of fiber optic cables vary depending on their type, length, and brand. A typical price range for a 100m single-mode yellow fiber optic cable is around USD 50-100 per meter.
Conclusion
Understanding the colors of communication cables and their corresponding prices is essential for selecting the right cable for your application. Each color has specific uses in telecommunications, and the prices vary depending on factors such as length, material, grade, and brand. By knowing the prices of each color of cable, you can make informed decisions when purchasing cables for your communication projects.
