Exfo FVA-60A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Exfo FVA-60A. 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 Exfo FVA-60A 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.

Exfo FVA-60A calibration cost
NIST-traceable calibration for the Exfo FVA-60A 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 →
