Loose tube cables with 36 fibers or less are composed of up to 6 color-coded fibers in individual color-coded tubes. Higher fiber
counts are composed of up to 12 fibers in individual color-coded buffer tubes. For cables containing more than 144 fibers, a black stripe
is added to duplicate color-coded tubes to make recognizable groups.
For example: A 24 fiber loose tube cable will have 6 fibers in each of 4 tubes. The tube colors will be blue, orange, green and brown.
Fiber colors will be blue, orange, green, brown, slate, and white. Fibers are identified by tube color/fiber color. Blue/White is the white
fiber in the blue tube.
Tight buffered distribution cables with 12 fibers or less will be colored according to the chart under a single jacket. Higher fiber
counts will be grouped in subunits of 6 or 12 color-coded fibers each. Tight buffered breakout cables contain a single fiber in each subunit
with the buffer color varying for each 12 subunit set. Subunit jackets can be color-coded or numbered for identification.
In cables of mixed fiber types (hybrids), the multimode fibers will begin the color sequence.
Outer jacket standard colors:
Premise cables with multimode fibers are ORANGE.
Premise cables with singlemode fibers are YELLOW.
Premise cables with mixed (hybrid) fibers are BLACK.
Indoor/Outdoor cables with any/all fibers are BLACK. |
