Fiber is used in long-distance phone networks because it is much cheaper than copper wire.
True or False?
True
Long distances mean fiber cable are spliced together, mostly by ?, because cables are not manufactured in lengths longer than about four to five kilometers.

A.) dust caps
B.) mating adapters
C.) sticky tape
D.) strain relief boots
A.) dust caps
