Return loss
Expressed by the ratio of the total reflected optical power (Pr) from optical system or
optical fiber to the incident optical power (Pi), and calculated by the following formula.
RL=−10log (Pr/Pi) [dB]
S/N
Signal to noise ratio. “Low S/N” means that the trace contains a lot of noise.
Sampling count
Quantity of data acquired for each trace. The sampling count must be determined by the
user.
For the method of selecting a sampling count, refer to page 3-28.
