FTTx Self Study Program, Lesson 5



True/False
Indicate whether the statement is true or false.
 

 1. 

As with any fiber optic network, testing is greatly simplified when one has proper documentation for the system.
 

 2. 

The loss of the link between the CO and the home (called insertion loss) is measured with an optical loss test set (light source and power meter) and should be measured at all wavelengths used in the system.
 

 3. 

Reflectance is important because of the short links in FTTx, especially in systems using analog video.
 

 4. 

ONTs usually have loopback testing for self-diagnosis.
 

Multiple Choice
Identify the choice that best completes the statement or answers the question.
 

 5.

A.
Optical Time Domain Reflectometer (OTDR)
B.
Optical Loss Test Set (OLTS)
C.
Visual fault locator (VFL)
D.
Optical Power Meter (OPM)
 

 6. 

This OTDR trace is taken in the direction ________.

A.
Downstream from the CO to the subscriber
B.

Multiple Response
Identify one or more choices that best complete the statement or answer the question.
 

 7.

 A.
PON splitter
