JDS Fitel / JDS Uniphase / JDSU VA4 Series Manual Variable Optical Attenuator Calibration and Repair Services

Simbol Test Systems provides professional in-lab JDS Fitel / JDS Uniphase / JDSU VA4 Series manual variable optical attenuator calibration and repair services to help maintain accurate, stable performance for your fiber optic test and measurement equipment. The JDS Fitel / JDS Uniphase / JDSU VA4 Series is a family of handheld manual variable optical attenuators designed for field fiber testing, laboratory development, and optical network troubleshooting.

The JDS Fitel / JDS Uniphase / JDSU VA4 Series includes multiple configurations used for controlled optical signal reduction in single-mode fiber applications. Common variants include the VA4503 Series for standard 1300 nm / 1550 nm testing, as well as VA47G and VA47K versions used in applications requiring stable attenuation and strong return loss performance. Select models may also include a Universal Connector Adapter (UCA) option for interchangeable SC, ST, and FC connector tips.

If your unit shows attenuation accuracy issues, control instability, connector wear, excessive loss, or other operating problems, we can review the failure condition and provide service recommendations based on the exact model and connector configuration.

Following calibration, your equipment may be returned with a calibration label, calibration certificate, and related calibration data. If the unit does not successfully complete calibration, we can evaluate the repair requirements and provide a repair quotation for approval before proceeding.

Traceability: Instrumentation used during this calibration is traceable to N.I.S.T. (National Institute of Standards and Technology) or C.N.R.C. (Canadian National Research Council), where applicable.
