FTTx Basic

What is the purpose of a fiber demarcation box?

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

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 best approach to repairing an aerial fiber-optic drop cable for FTTx applications?

Replace the entire section of fiber drop cable.

What is the purpose of the ground block?

To protect fragile electronics like TVs and STB Set-top boxes from damaging lightning strikes and power surges.

What is the difference between the FTTN Fiber-to-the-node and FTTC Fiber-to-the-curb topologies?

An FTTC is allowed a smaller number of RF Radio frequency amplifiers between the optical fiber and the customer premises.

What is the proper way to handle fiber once it is spliced?

At the heat-shrink protective sleeve that has a steel bar inside it.

In a PON FTTx network, which OSP device contains fiber test points that will minimize service disruption to customers?

FDH Fiber distribution hub

What parameter is critical in an OTDROptical time domain reflectometer when testing a PONPassive optical network with significant splitters losses?

High dynamic range.

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

Home-run

What is an ONU/ONTOptical network unit/optical network terminal?

It is a device that converts light from fiber to RF Radio frequency for coaxial distribution into the home.

What is true about using a premade fiber-optic pigtail for splicing to patch panels or terminal equipment?

It is faster and more reliable than installing connectors in the field.

What are the characteristics of ITU-TInternational Telecommunication Union G.657 BIFBend-insensitive fiber?

It is flexible for installation in small spaces and has a small bend radius of 7.5 mm Millimeters or 10 mm.

What are the advantages of loose buffer tube fiber?

It offers the best protection for the fibers under high pulling tension and moisture with its fiber-coated gel.

What is the purpose of the SDUSingle dwelling unit?

It provides surge protection, a test jack, circuit protection, wiring management, and fiber termination.

Which PON Passive optical network element uses patch panels?

ODN Optical distribution network

What is the one main function of the 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.

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.
