Various colors of fiber optic cabling components including fiber optic cables, connectors and adapters add color and life to data center. Image if there is no color coding of these fiber optic cabling components, the data centers which are full of a dense mass of server racks and cabinets will get into a mess. But if we make the fiber optic cabling components coding as we wished, it will cause many issues for the systems. Thus, the industry provides some standard to solve the issues.
Identify Type of Fiber by Color
The jacket color of fiber optic cable is typically defined by the fiber type, and will almost always follow the color definitions below. Both multimode and single-mode cables designed for outdoor use will typically have a black jacket to protect the cable from damage due to solar exposure and UV light.
Connectors and Adapters Identification
TIA-568-C.3 standard specifies the color codings for fiber connectors and adapters. Unless the color coding is used for some other purpose, the connector strain relief and adapter housing should be identifiable by the following colors:
As introduced above, the color coding of fiber optic cabling components are not just for looking pretty but for better management. In practical applications, we will need different color jackets of cable, connectors or adapters for individual management. But most of the times, we should obey the standards for our fiber optic cabling. And we can manage our cabling with different color ties and markers.
