Introduction
Communication cable trunking plays a crucial role in the efficient transmission of data, voice, and video signals across various communication networks. It is essential to understand the different规格型号 of communication cable trunking to ensure that the right equipment is used for specific applications. In this article, we will provide an in-depth guide to communication cable trunking specifications and models, covering everything you need to know about this essential communication component.
Chapter 1: Introduction to Communication Cable Trunking
1、1 Definition of Communication Cable Trunking
Communication cable trunking refers to the underground wiring system designed to transmit data, voice, and video signals within a specified distance. The system includes a network of wires, cables, and connectors that are connected together to form a continuous path for data transmission.
1、2 Types of Communication Cable Trunking Systems
There are two main types of communication cable trunking systems: passive and active. Passive cable trunking systems use coaxial cable, while active cable trunking systems use fiber optic cables. Each type has its advantages and disadvantages, depending on the specific application requirements.
1、3 Importance of Communication Cable Trunking
Effective communication requires reliable and efficient transmission of data, voice, and video signals. Communication cable trunking plays a vital role in achieving this goal by providing a secure and uninterrupted connection between devices and networks. Without proper communication cable trunking, data transmission may be slow, intermittent, or completely unreliable.

2、1 Coaxial Cable Trunking
Coaxial cable trunking is commonly used in passive communication cable trunking systems. It consists of an inner copper wire wrapped around an outer polyethylene insulation layer, with a center conductor running through both layers. Common specifications for coaxial cable trunking include:
- Diameter: 12mm (0.5英寸), 16mm (0.6英寸), 20mm (0.8英寸), 25mm (1英寸), 32mm (1.3英寸), and 40mm (1.67英寸)
- Core thickness: 0.375 inches (0.945cm) for 12mm diameter cable, 0.5 inches (1.27cm) for 16mm diameter cable, and 0.625 inches (1.58cm) for 20mm diameter cable
- Shielding: Polychloroprene (PVC) or aluminum foil tape shielding can be used to protect the inner conductor from external interference
- Maximum operating temperature: -40°C (-40F) to 85°C (185F)
- Conductivity: From 40 to 75 Ohm/km at room temperature (20-25°C)
- Max voltage rating: Up to 600V for UHF/AM frequencies and up to 36V for SDH/SONET/SDH-SDR frequencies
2、2 Fiber Optic Cable Trunking
Fiber optic cable trunking is commonly used in active communication cable trunking systems. It consists of thin glass or plastic fibers surrounded by protective layers, with a core made of glass or plastic fibers. Common specifications for fiber optic cable trunking include:
- Core size: Ranging from 62.5μm to 125μm for different applications, with larger cores providing higher bandwidth and lower signal loss
- Number of cores: Single-mode fibers typically have one core, while multimode fibers can have multiple cores arranged in different patterns such as round, square, or star shapes
- Connectors: Fused connectors are commonly used for fiber optic cable trunking, with options including LC (low-density), SC (standard), MTRJ (Mating Ring Joint), and ST (Straight Through) connectors
- Operating temperature: Fiber optic cables can operate effectively over a wide range of temperatures, from -10°C (-22F) to +70°C (+158F) depending on the specific type of fiber and the application requirements
- Wavelength range: Fiber optic cables can transmit signals over different wavelength ranges, from infrared light (IR) to ultraviolet light (UV), with common wavelengths ranging from 13μm to 130μm for indoor applications and longer wavelengths for outdoor applications such as satellite communications or long-distance data transmissions.
Chapter 3: Communication Cable Trunking Models and Features
3、1 Choosing the Right Model Based on Application Requirements
When selecting a communication cable trunking model, it is essential to consider factors such as maximum operating temperature, frequency range, number of cores, connector type, and other specific application requirements. For example, if the application requires high bandwidth and low signal loss, a single-mode fiber with a larger core size may be more appropriate than a multimode fiber with smaller core sizes. Similarly, if the application requires long-distance transmission over open terrain or natural barriers
