OPTICAL TEST CALIBRATORS
Oct 2002dBm Optics Inc.Request Info
Optical test system calibrators from dBm Optics Inc. are available in rack- mount (model OTC-4200) and benchtop (model OTC-4202) versions and can be purchased as individual devices. They provide certified calibration standards for polarization-dependent loss (PDL), optical return loss (ORL) and wavelength. Wavelengths range from 1255 to 1638 nm, with accuracies better than 0.3 pm. PDL and ORL values, which can be calibrated over the entire C- and L-bands, range from 0.05 and 0.75 dB with drift <0.005 dB per year, and from 0 to 100% return, respectively. The calibrators validate specifications of test systems for optical components and subsystems.
