The Kingfisher traceable optical calibration laboratory is IEC / ISO17025 accredited and can calibrate optical power, loss, return loss and wavelength EXFO calibration services ensure your test instruments deliver precise, reliable results. With calibration experts, advanced facilities, and. FIS Calibration and Verification services ensure your fiber optic test equipment remains accurate. It is recommended practice to keep fiber optic test equipment calibrated in measurement to ensure fast troubleshooting when locating network failures or when providing optical attenuation or optical. Work in Bahamas Role and Pay Precision-instrument makers and repairers Precision-instrument makers and repairers Precision-instrument makers and repairers make, calibrate, repair, maintain, adjust and install mechanical watches, clocks, nautical, meteorological, optical, orthopaedic and other. An optical power meter is the most common type of test equipment used to support fiber optic system. NIST developed a testing system to provide absolute power calibrations for optical power meters. Fiber optic equipment can be affected by various factors, such as temperature, humidity, dust, connectors, and cables, that can degrade its performance over time.
