とおりである。 The light emitted from the standard light source 11 is transmitted between the optical connector attached to the optical fiber cable 3 and the standard light source 1.
The light emitted from the standard light source 11 is connected to the optical adapter attached to the optical fiber cable 1 at the optical connector connection part 12, and the light emitted from the standard light source 11 is transmitted to the optical detector via the optical fiber cable 3, the splice part 13, and the fiber cable to be measured 14. The light is received at the optical power meter 15 and the optical power is displayed on the optical power meter main body 16. For example, when performing a temperature resistance characteristic test on the optical fiber cable 14 to be measured, the optical fiber cable 14 to be measured is
By housing the standard light source 1 in a constant temperature bath 17 and periodically changing the internal temperature of the constant temperature bath
When the light emitted from the optical power meter main body 1 passes through the thermostatic chamber 17, the optical loss increases and decreases.
6. The formula for calculating the optical loss fluctuation is as follows.

誤差を防止したものである。 Optical loss (dB) = Optical loss (dB) at a certain temperature setting
-The optical loss (dB) at the reference temperature, the time required for the temperature resistance characteristic test is sometimes continuously carried out for nearly 10 hours, and during this time it is normally strictly prohibited to touch the measuring equipment, optical fiber cables, etc. It is said that This is because if an external force is applied unnecessarily to the optical fiber cable, etc. that constitutes the optical transmission loss measurement system, some external force will act and the optical power meter main body 16 will fluctuate, which is completely different from the fluctuations due to temperature changes caused by the thermostatic oven 17. Since the power is displayed, a protective structure is attached to the optical connector connecting portion 12 to prevent the fluctuation error.
