This unit

The Exfo FVA-80-B50-C22-IE is a dual-channel variable optical attenuator integrating singlemode and multimode functionality within a single portable unit. Each channel operates independently with dedicated optical interfaces, enabling precise attenuation control across multiple wavelengths and fiber types. The instrument delivers up to 65 dB maximum attenuation with 0.01 dB optical resolution and insertion loss below 3.0 dB, making it suitable for R&D, production testing, and field deployment.

Exfo FVA-80-B50-C22-IE — Repair & Calibration Service

Aumictech offers NIST-traceable calibration and repair for the Exfo FVA-80-B50-C22-IE. 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-80-B50-C22-IE 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-80-B50-C22-IE calibration cost

NIST-traceable calibration for the Exfo FVA-80-B50-C22-IE 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 →
