Quiz9-Passive Optical Network

"Active Optical Network (AON) needs active splitters by means of aggregation switches, which need power to boost and distribute the signal. The switch will route the correct signal to the intended recipient."

• True

• False

"For optical splitters, the more the light is split, the lesser the attenuation (optical power loss)."

• True

• False

"Passive Optical Network (PON) sends same signals to all end users, lower band width expected at peak usage."

• True

• False

"Which of the following is a method of connecting two fibers, whereby two fibers are precisely cleaved and fused by an electric arc."

• Splitting

• Dicing

• Splicing

• Slicing

"The purpose of an OTDR is to detect, find, and measure events at any location on a fiber link. An OTDR can detect (multiple answers)"

• Fiber misalignment

• Fiber mismatch

• Fiber breaks

• Macrobend

"Downlink data flow uses Wavelength Division Multiplexing (WDM) technology, which multiplexes a number of optical carrier signals onto a single optical fibre, by using different wavelengths (i.e., colours) of laser light."

• True

• False

The main benefits of PON are (multiple answers)

• Lower installation (CapEx) costs

• Easier to hack

• Network maintenance is easier

• Completely avoid electromagnetic interference

A fiber distribution hub (FDH) is an enclosure that provides the connection between fiber optic cables and passive optical splitters in the outside plant segment of the network.

• True

• False

Optical network terminal (ONT) provides the interface between the customers networks and the PON. Its function is to ONT converts fiber-optic light signals to copper/electric signals.

• True

• False

"Fiber loss can be also called fiber optic attenuation or attenuation loss, which measures the amount of light loss between input and output. It is also proportional to the length of cable."

• True

• False
