Optical fibers transmit high power levels, provided that the fiber end facets are of high quality. The smoother the surface, the more power can be coupled. Therefore, all connectors should be tested after assembly. The attenuation (i.e., the ratio between the power going into the fiber vs. the power exiting the fiber is) is measured as well. The smaller the attenuation, the higher the performance of the fiber assembly is and the longer the transmission range.
Comfortable measurement. You do not have to be an engineer to perform reliable attenuation measurements. The measurement kits by Greenlee support you in your work. The kit consists of
- An optical source
- An optical power meter
- A reference cable
- A reference coupling
The tolerances of the kit components are particularly tight, which enables a high precision. The measurement results are hence reliable. Not using reference components would lead to high inaccuracies and incorrect measurement results in the parts being tested.
Note: During attenuation measurements, you only need to make sure that the fiber type and numerical aperture of both the reference cable and the cable being tested are the same. For example, if a GI50/125 fiber is being measured, the reference cable also has to consist of a GI50/125 fiber.
