Surveillance fiber optic cables are typically sorted by color coding, fiber type (single-mode or multi-mode), and connector configuration to ensure proper network organization and signal routing.

Fiber Type and Mode

Fiber optic cables used in surveillance systems are generally single-mode or multi-mode. Single-mode fibers support long-distance transmission with a small core, while multi-mode fibers have a larger core suitable for shorter distances and higher bandwidth within buildings or campuses . Sorting cables by mode is essential because mixing them can cause signal loss or incompatibility with SFP modules and media converters .

Color Coding

Each fiber strand within a cable is usually color-coded to simplify identification and management. Standard color codes follow industry norms, such as blue, orange, green, brown, slate, white, red, black, yellow, violet, rose, and aqua for the first twelve fibers, with repeating patterns for larger counts . This allows technicians to quickly identify and connect the correct fibers to switches, cameras, or SFP modules.

Connector and Pairing

Fiber strands are often paired for bidirectional communication, with one fiber transmitting and the other receiving. These pairs are terminated with connectors such as LC, SC, or ST, depending on the equipment . Proper sorting ensures that transmit and receive fibers are correctly matched, preventing network errors.

Cable Management

In large surveillance installations, fibers are organized in patch panels, trays, or conduits. Each fiber is labeled according to its destination, camera ID, or switch port. This structured approach reduces confusion during maintenance, troubleshooting, or future expansion . Documentation of fiber routes and connections is also critical for efficient network management.

Integration with Network Equipment

Fiber optic cables connect to SFP modules, media converters, and network switches. Sorting fibers correctly ensures that each camera's signal reaches the intended recording device without interference. Multi-mode and single-mode fibers are matched to compatible SFP modules, and color-coded strands help maintain consistent connections across the network . By following these sorting practices—fiber type separation, color coding, pairing, labeling, and structured management—surveillance fiber optic networks achieve reliable, high-speed, and long-distance video transmission.
