The color coding of fiber optic cables is typically determined based on the standards set by the International Telecommunication Union (ITU-T) or the Electronic Industries Alliance/Telecommunications Industry Association (EIA/TIA). Below are the common fiber optic color codes:
The color sequence of optical fibers in loose tubes (Chinese National Standard fiber order)
The color sequence for 12-fiber optic cables is: blue, orange, green, brown, gray, white, red, black, yellow, violet, pink, aqua.
The color sequence for 24-fiber optic cables is: composed of 4 tubes, each containing 6 fibers with the colors blue, orange, green, brown, gray, and white.
The color sequence for 48-fiber optic cables is typically divided into four bundles, each bundle containing 12 fibers with the colors blue, orange, green, brown, gray, white, red, black, yellow, violet, pink, and aqua.
The color sequence for 144-fiber optic cables typically consists of 12 bundles, with each bundle arranged in the color sequence of blue, orange, green, brown, gray, white, red, black, yellow, violet, pink, and aqua per 12 fibers.
This color coding method ensures that each fiber optic cable has a unique identification within multi-fiber cables.

Common fiber optic cables include 4-fiber, 12-fiber, 48-fiber, 96-fiber, and 144-fiber cables.
The color sequence for 4-fiber optic cables is: blue, orange, green, brown.
The color sequence for 24-fiber optic cables is: composed of 4 tubes, each containing 6 fibers with the colors blue, orange, green, brown, gray, and white.
The color sequence for 48-fiber optic cables is typically divided into four bundles, each bundle containing 12 fibers with the colors blue, orange, green, brown, gray, white, red, black, yellow, violet, pink, and aqua.
The color sequence for 96-fiber optic cables has two configurations:
12 tubes, each containing 8 fibers with the colors blue, orange, green, brown, gray, white, red, and black.
8 tubes, each containing 12 fibers with the colors blue, orange, green, brown, gray, white, red, black, yellow, violet, pink, and aqua.
The color sequence for 144-fiber optic cables typically consists of 12 bundles, with each bundle arranged in the color sequence of blue, orange, green, brown, gray, white, red, black, yellow, violet, pink, and aqua per 12 fibers.
This color coding method ensures that each fiber optic cable has a unique identification within multi-fiber cables.
