existing fiber networks tenfold without adding any more fiber.
How are optical splitters used in the forward path? - Answer As passive branching devices that divide
an optical signal across multiple output fibers.
What is the purpose of a fiber demarcation box? - Answer It provides a safe place to splice, split,
distribute, store, and cross-connect fiber optics.
What is the purpose of the MST? - Answer It provides access to connect fiber-optic cable drops from
the customer premises to the network.

What le true about using a premade fiber-optic pigtail for
splicing to patch panels or terminal equipment? - Answer It is faster and more rellable than installing
eonnectors in the
field.
What is the proper way to handle fiber once it is spliced? - Answer At the heat-shrink protective sleeve
that has a steel bar inside it.
What is the purpose of the ground block? - Answer To protect fragile electronics like TV's and STBs
from damaging lightning strikes and power surges.
