This unit
The JDS Uniphase HA3 is a programmable optical attenuator engineered for precision optical power control across telecommunications and laboratory test environments. It delivers 0 to 60 dB attenuation with 0.0005 dB resolution and ±0.1 dB accuracy, making it essential for power meter calibration, analog transmission characterization, and bit error rate testing. The device minimizes optical reflections and cavity effects to ensure measurement integrity across single-mode fiber systems from 1200 to 1700 nm.

JDS Uniphase HA3 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the JDS Uniphase HA3. 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 HA3 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 HA3 calibration cost
NIST-traceable calibration for the JDS Uniphase HA3 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 →
