Home run.

What is the purpose of the MST? (Multiport Service Terminal)

It provides access to connect fiber-optic cable drops from the customer premises to the network.

What is the main benefit of deploying WDM? (Wavelength division multiplexing technology)

What are the three categories of the fiber-optic cable used to identify the location of the fiber in the network?

Trunk, branch and drop.

How are optical splitters used in the forward path?

As passive branching devices that divide an optical signal across multiple output fibers.

What is the difference between the fiber-to-the-node (FTTN) and fiber-to-the-curb (FTTC) topologies?

An FTTC is allowed a smaller number of RF amplifiers between the optical fiber and the customer premise

What is the purpose of a fiber demarcation box?

It provides a safe place to splice, split, distribute, store, and cross-connect fiber optics.

Which PON element uses patch panels?

ODN

What is the one main function of FDH? (Fiber Distribution Hub)
