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.
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.
In a PON FTTx network, which OSP device contains fiber test points that will minimize service disruption to customers?
FDH (Fiber Dist) Hub
What parameter is critical in an OTDR (Optical time domain reflectometer) when testing a PON (Passive optical network) with significant splitters losses?
HDR - High Dynamic Range
What is an ONU/ONT (Optical 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-T G.657 BIF?
It is flexible for installation in small spaces and has a small bend radius of 7.5 mm Millimeters or 10 mm.
What is the purpose of the SDUSingle dwelling unit?
