This unit
The JDS Uniphase VA5503-FAS is a precision variable attenuator for single-mode optical networks requiring accurate control of optical signal levels. Handheld and portable, this instrument delivers manual attenuation adjustment with 0.1 dB resolution and maintains settings across power cycles. Its large-format LCD display provides real-time readout of attenuation values, making it essential for network testing, laboratory measurements, receiver characterization, and field system troubleshooting.

JDS Uniphase VA5503-FAS — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the JDS Uniphase VA5503-FAS. 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 VA5503-FAS 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.

JDS Uniphase VA5503-FAS calibration cost
NIST-traceable calibration for the JDS Uniphase VA5503-FAS is $450 (standard — pass/fail certificate and calibration sticker) or $650 (full measured data at every test point, reference standards documented, traceability chain included). Calibration for this instrument 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. Turnaround is 1 to 3 business days after receipt. See full calibration details →
