Chapter 6 Quiz - Cables



    1.    ANS:    T
Conductive cables must be grounded and bonded for electrical safety per electrical codes.

    2.    ANS:    T
Installation specs will include pulling tension or aerial cable tension while the environment will cover temperature, moisture, etc.


    3.    ANS:    B
Sometimes confused with composite cables which have copper conductors and fiber.

    4.    ANS:    C
Sometimes confused with hybrid cables which have both SM and MM fibers.

    5.    ANS:    A
All indoor cables must be rated for flame retardance for the NEC to pass building inspections.

    6.    ANS:    D
Moisture is a problem in all outdoor cables, while the other choices may apply in certain circumstances.

    7.    ANS:    B
Ribbon cables pack the most fibers into the smallest cable.

    8.    ANS:    A
Loose tube cables allow for the greatest pulling tension.

    9.    ANS:    B
Breakout cable is just a jacketed bundle of simplex cables which are easy to terminate and require no additional hardware for protection.

    10.    ANS:    D
All cables are designed to be pulled with the strength members, usually aramid yarn, not the jacket.

    11.    ANS:    B
The 250 micron buffered fibers are too fragile to work with until sleeved with furcation tubes in a breakout kit.

    12.    ANS:    A
Armor provides protection from rodent penetration.

    13.    ANS:    C
When not under tension, the cable should withstand bending on a radius 10 times the cable diameter. Under tension, it's 20 times.

    14.    ANS:    C
PE resists water and the black color resists sunlight.
