Fiberstore cables: How to identify the color code of Fiber optic cable

Posted on by FS.COM

There are so many types colored fiber optic cables, and these cable color can tell you which type cable you are dealing with. TIA-598C addresses the color code standards which we could adopt and reference:

Non-military Applications

Orange: OM1 62.5-Micron Multimode
Orange: OM2 50-Micron Multimode
Aqua: OM3 Laser-Optimized 50-Micron Multimode
Aqua/Violet*: OM4 Laser-Optimized 50-Micron Multimode. OM4 cable is not specified in the standard. Aqua is used for OM3/OM4 cable (and some higher-grade OM2 cable). Violet is used for OM4 cable in Europe and is becoming more common in North America.
Yellow: OS1/OS2 Single-mode
Blue: Polarization-maintaining (PM)Single-Mode
Black: Outdoor fiber

Military Applications

Slate: 62.5-Micron Multimode
Green: 100/140 Micron Multimode
Orange: OM2 50-Micron Multimode
Yellow: OS1/OS2 Single-mode
* OM3 OM4 & PM singlemode is Undefined.

Inner Cable Organizational Color Coding

Bare fiber are stranded in a loose tube cable. It is simple to recognize the cables and fast to complete the fiber link when you clearly know the color code.

Fiber Position Color and Tracer Sample
1 Blue blue
2 Orange orang
3 Green green
4 Brown Brown
5 Slate salte
6 White write
7 Red white
8 Black Black
9 Yellow yellow
10 Violet Violet
11 Rose Rose
12 Aqua Aqua
13 Blue/Black Brown Black
14 Orange/Black OrangeBlack
15 Green/Black GreenBlack
16 Brown/Black Brown Black
17 Slate/Black SlateBlack
18 White/Black White Black
19 Red/Black Red Black
20 Black/White Black Yellow
21 Yellow/Black YellowBlack
22 Violet/Black Violet Black
23 Rose/Black Rose Black
24 Aqua/Black aque Black

Connectors color code:

The advent of metallic connectors like the FC and ST made connector color coding difficult, so colored strain relief boots were often used. The connector strain relief and adapter housing should be identifiable by some color codes listed in TIA 568-C.3.

Fiber Type Connector Connector/Boot
OM1 62.5-Micron Beige/Black/Aqua Beige
OM2 50-Micron Beige/Black/Aqua Black
OM3 50-Micron Beige/Black/Aqua Aqua
Single-mode Blue Blue
Single-mode APC Green Green

The fiber connector/strain-relief boots are also color coded to indicate the polish style of the fiber endface:

Connector Boot Endface Fiber Type
Blue UPC Single-mode
Green APC Single-mode
Black UPC OM2 50-Micron
Grey/Beige UPC OM1 62.5 Micron
White UPC OM3 50-Micron

The boot colors may vary by manufacturer.
