USB Microscope
A USB microscope can be connected to the device for plug connector inspection. The device
supports DI-1000 type USB microscopes from Lightel Technologies.
Contamination in optical plug connections can impair the signal quality. Typical types of
contamination include dust particles, hand lotion, skin and alcohol residues.
Figure 16-4 typical contamination on the optical fibers
Contamination on the optical fibers can cause the following problems:
•
the signal path can be disrupted in the core region
•
good physical contact can be prevented in the plug connector
•
cause scratches and associated damage
The following figure shows a typical example of a poor physical contact in a plug connector. Here, a
dust particle prevents the two optical fibers from creating a flush contact with one another.
