Section 1: Introduction to Communication Bridge Cables
1、1 Types of Communication Bridge Cables
There are several types of communication bridge cables, each designed to meet specific requirements. Some of the common types include:
- Power Cables: These cables carry electrical energy from the power source to the devices connected to the bridge. They are typically made of thick insulation materials and have high voltage ratings.
- Data Cables: These cables transmit data between devices connected to the bridge. They can be classified based on their speed, such as fast Ethernet (10 gigabit Ethernet), high-speed fiber optic (10 Gbps or higher), and ultra high-speed (40/100 Gbps or higher).
- Control Cables: These cables control the operations of the bridge, including its mode selection, signal conditioning, and error correction. They are typically used for manual operation or during maintenance tasks.
- Signaling Cables: These cables transmit signaling information between devices connected to the bridge. They may include video, audio, or control signals depending on the application.
1、2 Cable Functions in Communication Bridges
Each type of communication bridge cable performs a specific function in maintaining a reliable and efficient communication system. For example:
- Power Cables: Provide electrical energy to devices connected to the bridge, ensuring they operate correctly.
- Data Cables: Transmit and receive data between devices, allowing them to communicate with each other seamlessly.
- Control Cables: Enable users to control various aspects of the bridge's operation, such as its mode selection or signal conditioning.
- Signaling Cables: Transmit signaling information between devices, allowing them to exchange messages or instructions.
1、3 Importance of Cable Markings
Cable markings play a critical role in identifying the specific type and function of each cable within a communication bridge. Clear and consistent cable marking helps prevent errors during installation, maintenance, and troubleshooting. Additionally, it enables technicians to quickly identify the correct type of cable needed for a particular task without having to consult manuals or other documents extensively.

2、1 Common Cable Markings and Symbols
Several standard symbols are used globally to represent communication bridge cables. These symbols help distinguish between different types of cables and their functions within the system. Some common cable marking symbols include:
- Power Cord Markings: A red triangle with an exclamation point inside represents a live electrical power cord. A black circle with a slash through it indicates a dead or disconnected power cord. A black triangle with a dot inside represents a neutral cord.
- Data Cable Markings: A white dot inside a blue square indicates a twisted pair Ethernet cable. An orange dot inside a blue square represents an unshielded twisted pair Ethernet cable. A yellow dot inside a blue square represents a shielded twisted pair Ethernet cable. A white dot inside a green square represents an optical fiber cable. An orange dot inside a green square represents an unshielded optical fiber cable. A yellow dot inside a green square represents a shielded optical fiber cable. A white dot inside a purple square represents a coaxial cable. An orange dot inside a purple square represents an unshielded coaxial cable. A yellow dot inside a purple square represents a shielded coaxial cable.
- Control Cable Markings: A white dot inside a gray square represents a manual control cable. An orange dot inside a gray square represents an automatic control cable. A yellow dot inside a gray square represents an emergency stop control cable. A white dot inside an orange square represents an auxiliary control cable. A white dot inside a blue square represents an input signal control cable. A white dot inside a green square represents an output signal control cable. A white dot inside a purple square represents an error signal control cable. A white dot inside an orange circle represents an alarm control cable. A white dot inside a gray circle represents an reset control cable. A white dot inside a blue circle represents an enable control cable. A white dot inside a green circle represents a disable control cable. A white dot inside a purple circle represents an override control cable.
- Signaling Cable Markings: A white dot inside a red triangle represents video signaling information. A white dot inside an orange triangle represents audio signaling information. A white dot inside a blue triangle represents control signaling information. A white dot inside a green triangle represents data signaling information. A white dot inside a purple triangle represents signaling information for another type of device or system (e.g., remote controls or other control centers).
2、2 Understanding Cable Markings and Their Meanings
To fully comprehend the meaning behind cable markings, it is essential to consider their context within the communication bridge system. Here are some key factors to keep in mind when interpreting cable markings:
- Placement: Cable markings are typically located on or near the connector ends of cables within the bridge system. This placement serves as visual cues indicating the type and function of the cable being used at that location.
- Color Coding: Many cable marking symbols use color coding to differentiate between different types of cables or signal levels within the system. For example, blue squares with white or yellow dots may represent different types of data cables with varying signal levels or protection mechanisms (e.g., unshielded versus shielded). Similarly, red triangles with different color dots may indicate various types of power cords with different voltage ratings or safety features (e.g., no-contact power cords versus grounded power cords).
- Shape Decoding: Some cable marking symbols use shape codes to represent specific functions within the system. For example, triangles with arrows pointing towards them may indicate directionality (e.g., incoming data from one end vs outgoing data to another end). Squares with lines crossing them may signify multiple purposes (e.g., Ethernet cables that can carry both data and signaling information). Circles with numbers or letters may indicate specific parameters or settings (e.g., bandwidth limits for data cables). Rectangles with diagonal stripes may represent alternating current (AC) connections (e.g., power cables with alternating current flowing). Circles with diagonal stripes may also denote alternating current (AC) connections (e.g., optical fibers that use AC signals). Circles with lines crossing them may signify multiple purposes (e.g., control cables that can perform multiple functions). Circles with letters or numbers within them may represent specific parameters or settings (e.g., error code meanings for signaling cables). Circles with letters or numbers within them may also denote specific applications or services (e.g
