Lesson 1 Exam FTTx Elements - NEW 2023

Which type of fiber topology used in a PON places the PON splitters at the headend while providing one designated fiber for every customer premise?

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)

It will increase the capacity of the existing fiber networks tenfold without adding any more fiber.

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)

The FDH provides effective fiber management by grouping splitters into local serving areas.

What is unique about WDM-PON? (Wavelength division multiplexing-passive optical network)

WDM-PON deployed in a greenfield system allows each subscriber to get their own designated wavelength.
