Answers To Chapter Questions


Chapter 7 Quiz - Termination and Splicing

TRUE/FALSE

    1.    ANS:    T
Terminatingsinglemode is difficult in field conditions so they are generally made by fusion splicing factory made pigtails onto the fibers.

    2.    ANS:    T
SC has a 2.5 mm ferrule and the LC a 1.25 mm ferrule, making alignment impossible.

MULTIPLE CHOICE

    3.    ANS:    B
The first connector standardized by TIA-568 was the SC but now any connector with a FOCIS document is allowed.

    4.    ANS:    D
The first connector standardized by TIA-568 was the SC but now any connector with a FOCIS document is allowed.

    5.    ANS:    A
Most factory-made terminations are epoxy-polish type as they are the most reliable and least expensive.

    6.    ANS:    B
The splice in the prepolished connector must be well made and that requires a good cleave on the fiber.

    7.    ANS:    B
Connectors allow disconnecting and connecting multiple times while splices are permanent.

    8.    ANS:    D
Splices are permanent, so one looks for long term reliability instead.

    9.    ANS:    B
Singlemode systems are generally sensitive to reflectance.

    10.    ANS:    B
Cleaving the fiber properly is the key to good splices.

    11.    ANS:    C
The PC finish reduces both loss and reflectance.
