Answers To Chapter Questions
Chapter 6 Quiz - Cables
MATCHING
TRUE/FALSE
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.
MULTIPLE CHOICE
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.
