It’s the Little Things That Count

As they say, the devil is in the details. Knowing the little things that count can help get the job done, and save time and money. Let’s look at some little things that matter for fiber optics.

1. Which of these “little things” is the biggest problem with fiber optic connections?

Correct Answer: Dirt and contamination on connector ferrules

2. Using ______ when testing insertion loss of multimode cable will give you more consistent and lower-loss measurements.

Correct Answer: A mandrel wrap mode conditioner to the launch cable

3. When terminating fiber with cleave and crimp connectors with a mechanical splice in the connector, the results will be more consistent and lower by ______.

Correct Answer: All of the above

4. Mating a dirty fiber optic connector to a clean fiber optic connector can make both connectors and the connection dirty and high-loss.

Correct Answer: True

5. A desire to make smaller fiber optic connectors led to the development of the little ______ connector.

Correct Answer: LC

6. If an optical time-domain reflectometer (OTDR) shows a “gainer” on a splice, measuring from the other direction will show the ______.

Correct Answer: Greater loss than the actual loss
Correct Answer: A gainer also

7. If the OTDR measures the splice loss in both directions, even if there is a gainer in one direction, you can average the readings and get the ______.

Correct Answer: Splice's average loss

8. If you are patching cable connections on an installed cable plant that is 50/125 OM2 fiber but you have only 50/125 OM3 and OM4 patchcords, you ______.

Correct Answer: Can use either OM3 or OM4 patchcords to connect to the OM2 cable plant

9. Before splicing fibers, you must always clean the fiber carefully after cleaving it.

Correct Answer: False

10. Sometimes people say they are stripping the “cladding” when they strip fiber, but ______.

Correct Answer: All of the above
