Loose Tube Fiber Color Code

If fiber 13 24 are used in a loose tube design the color sequence is repeated for fiber 13 24 but fibers are ring marked.

Loose tube fiber color code. In loose tube cables this color code is used for tubes fibers within the tubes and subgroups from tia eia 598 a. Rose 11 th and aqua 12 th. Look up cable count reverse cable count custom start fiber straight sheath count or search by inverse color code with an expanding chart of fibers from a single screen. Fiber optic color code is a searchable expanding chart that translates the color code of loose tube and ribbon fiber optic cables including ribbon in loose tube cable types.

Fiber color codes inside the cable or inside each tube in a loose tube cable individual fibers will be color coded for identification. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed. Since most loose tube cables have 12 fibers per tube colors are specified for fibers 1 12 then tubes are color coded in the same manner up to 144 fiber cables. Fiber strands and cables are manufactured with a standard color coding.

Fibers follow the convention created for telephone wires except fibers are identified individually not in pairs. This allows for easy effective management and identification of strands. A fiber optic cable also known as an optical fiber cable is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. Fiber 20 is clear uncolored since ring marking will not be visible on black colored fibers.

Within each buffer tube would be 12 fiber strands using the same color. In ribbon cables each ribbon is color coded in this format then ribbons are stacked. Fiber optic color code is a searchable expanding chart that translates the color code of loose tube and ribbon fiber optic cables including ribbon in loose tube cable types. A loose buffer tube cable with 144 strands would have 12 tubes colored as indicated in the image below.
