March Quiz With Correct Answers and Explanations

Proper tools and test equipment are essential for the fiber optic installer. In my recent series on fiber optic installation, I discussed which tools and test equipment you need, so let’s see what you learned. Correct answers and explanations are in red.

1. Choosing the proper installation and test equipment is important, as it will affect the installation time and quality or even determine the profitability of the job.



Proper tools and test equipment will speed up installation and improve the quality of the work.

2. The tester that every installation tech should carry is a ________.

A. Optical time domain reflectometer (OTDR)

B. Optical power meter

C. Light source and power meter

D. Visual tracer or fault locator

A Visual tracer or fault locator will check for continuity or polarity (proper transmitter to receiver connections) and the visual fault locator can locate breaks or bending loss.

3. All fiber optic cable plants require testing with a ________.

A. Optical power meter

B. Light source and power meter or OLTS


D. All of the above

Every international standard requires testing with a light source and power meter or OLTS. Power meters test power at the receiver and OTDRs are troubleshooting tools.

4. Long outside plant cables generally require the installer to use a ________ for ________.

A. Fusion splicer, splicing long cables

B. OTDR, testing fusion splices and long cable runs

C. Visual fault locator, troubleshooting fibers too close for an OTDR

D. All of the above

All these are going to be needed to test and troubleshoot long OSP cables with intermediate spices.

5. When terminating adhesive/polish connectors, you can use the same oven for heat-cured epoxy and Hot Melt connectors.



Hot melt connectors use a much higher temperature than heat-cured epoxy that will ruin epoxies.

6. A ________ is necessary to get low losses with prepolished/splice connectors.

A. No-Nik stripper

B. Carbide scribe

C. Diamond scribe

D. High quality cleaver

The loss of a prepolished connector depends on the quality of the cleave on the fiber being terminated.

7. Reference patch cables for testing should be ________.

A. 1–2 meters long

B. Tested to have low loss

C. Checked for dirt and damage regularly

D. All of the above

All of these factors are important to get consistent, accurate test results.

8. To ensure proper use, light sources and power meters, OTDRs and fusion splicers all require ________.

A. Alternating current power

B. Charged batteries

C. Clean working conditions

D. Trained operators

None of these instruments will give good test results unless the operator is trained in the use of the instrument and interpretation of the test results.

9. Every tool and piece of equipment the installer will use on the job should be ________.

A. Checked before carrying it to the job site to ensure proper operation

B. Purchased from the manufacturer to match the components being used

C. Brand new

D. Bought at the cheapest price

No tool or test equipment should ever be taken to an installation until it’s operation has been checked and proper operation verified.

10. Along with tools and test equipment, every installer needs to wear ________.

A. Black clothing to help find fiber scraps

B. Safety glasses

C. A plastic apron

D. Gloves

Every fiber tech needs to wear safety glasses to protect their eyes from flying scraps, especially scraps of optical fiber.
