3 Overview
Communication optical attenuator for optical communications industry research and production is an important instrument, it is used to adjust the optical communications
Optical path optical power values, using a calibrated optical attenuator can be used to expand the range of standard optical power range, straight
Access to communication network services. Normal communication optical attenuator can be divided into fixed and variable optical attenuator optical attenuator are two, variable
Optical attenuator can be divided into a continuously variable type, step type, continuous and step combination.
4 metering performance requirements
a) Optical Attenuator Indication. (0 ~ 65) dB;
b) Optical Attenuator Repeatability. 0.8dB;
c) optical attenuator insertion loss. ≤3dB;
d) optical attenuator port return loss. ≥35dB;
e) optical attenuator input and output. optical fiber connector type is recommended for the FC/PC optical connector.
When the index is higher than this requirement inst
