This unit
The JDS Uniphase VA4503-FPL is a manual variable optical attenuator engineered for precise control of optical signal power in telecommunications, data center, and high-bandwidth testing environments. This handheld instrument delivers attenuation adjustment from 0 to 65 dB with 0.1 dB resolution, enabling accurate signal calibration and system optimization across multiple wavelength bands. Built on JDSU's ultra-linear attenuator prism and microlens technology, the VA4503-FPL combines laboratory-grade performance with field portability.

JDS Uniphase VA4503-FPL — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the JDS Uniphase VA4503-FPL. Calibration covers attenuation accuracy at 5 or more set values across the full range (0 to rated maximum dB), attenuation linearity, wavelength-dependent attenuation at 1310 nm, 1490 nm, and 1550 nm, insertion loss at minimum attenuation (0 dB position), and polarization-dependent loss (PDL) where applicable. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common JDS Uniphase VA4503-FPL faults: motor and gear mechanism wear (attenuation steps or loss of smooth control), optical port contamination, EEPROM calibration data corruption. Most common faults are motor or gear mechanism wear on variable attenuators causing attenuation steps or loss of smooth control, optical port contamination reducing dynamic range, and EEPROM calibration data corruption on digitally controlled models.
