Loose Tube Fiber Color Code

In ribbon cables each ribbon is color coded in this format then ribbons are stacked.

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. In loose tube cables this color code is used for tubes fibers within the tubes and subgroups from tia eia 598 a. Fiber strands and cables are manufactured with a standard color coding. 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 color codes inside the cable or inside each tube in a loose tube cable individual fibers will be color coded for identification. Within each buffer tube would be 12 fiber strands using the same color. This allows for easy effective management and identification of strands. 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.

A loose buffer tube cable with 144 strands would have 12 tubes colored as indicated in the image below. 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. Color code guide for fiber optic specifications expresslt cable designs fiber count number of tubes fillers number of tube layers number of tube fillers in each layer fiber position for each layer typical fiber overlength factor 2 to 60 5 1 5 2 to 60 1 018 62 to 72 6 1 6 62 to 72 1 028 74 to 96 8 1 8 74 to 96 1 024 98 to 120 10 1 10 98 to. 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.

Fibers follow the convention created for telephone wires except fibers are identified individually not in pairs. The color code used for fiber optics is similar to copper except for the addition of two colors. Rose 11 th and aqua 12 th. Fiber optic color code.
