The 588RL return loss test set is a completely self-contained instrument designed to measure back-reflections caused by fiber optic connectors and other single-mode devices. The 588RL employs the Optical Continuous Wave Reflectometry (OCWR) method to measure return loss from 0 to 70dB in the 1310nm and 1550nm wavelength regions.
After the 588RL 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 588RL 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.
A built-in serial port allows the 588RL to be controlled remotely from a computer, enabling the automation of complex or repetitive measurements. LabView and LabWindows drivers for the instrument are available from Tempo.
The 588RL can also be connected to a 570L Series benchtop optical power meter using the built-in I2C interface for efficient insertion loss and return loss testing in manufacturing or laboratory settings.
In addition, the 588RL features a BNC analog output interface for convenient external monitoring.
