308 × 293 × 60
Can calibrate OTDRs with various ranges and errors for measuring distance and attenuation
Can test dead zone values and dynamic ranges for various types of OTDRs (fiber spool required)
Equipped with built-in attenuators
Works in the modes of reproducing time intervals and optical signal amplitudes
Calibrates main OTDR parameters like distance measurement uncertainty and attenuation measurement uncertainty
Pulse amplitudes are set with the help of built-in optical attenuators
Loss created by IIT-xOG is measured by the high-accuracy receiver
Operation is based on forming an optical pulse with specified length, power, and delay relative to the pulse generated by the OTDR
Operating control and data processing are done by the PC
