Fiber U Color Codes Quiz



Multiple Response
Identify one or more choices that best complete the statement or answer the question.
 

 1. 

Color codes are used in fiber optics to identify ________. (Check all that are correct.)
 a.
Fibers
 b.
Premises cables
 c.
OSP Cable buffer tubes
 d.
Connectors
 

True/False
Indicate whether the statement is true or false.
 

 2. 

Singlemode cables which have blue connectors should not be mated to singlemode cables with green connectors.
 

 3. 

Above 12 fibers, the fibers will be bundled with color coded binder tape.
 

 4. 

Loose tube cables will have tubes following the color codes up to 12, then stripes on colored buffer tubes will indicate tubes 13-24, 25-36, etc.
 

 5. 

In addition to color codes, cables should have printing on the cable jacket to indicate fiber types and other relevant information like UL safety testing.
 

 6. 

When splicing two identical cables, fibers are spliced to the same colored fibers for consistency.
