Single-mode Return Loss Testing
The 585RL return loss test set is a completely self-contained instrument designed to measure backreflections caused by fiber optic connectors single-mode devices. The 585RL employs the Optical Continuous Wave Reflectometry (OCWR) method to measure return loss from 0 to 70dB 1310nm wavelength region.

After the 585RL is zeroed and referenced, the operator measures return loss by taking the optical fiber immediately after the device under test and wrapping it around a supplied mandrel. The 585RL prints customized labels containing measurement, date, and time information when connected to a parallel or serial printer. Up to seven different label formats can be stored in non-volatile memory for later use.
