This unit
The 3M/Photodyne 19XT-062T is a portable variable optical attenuator engineered for precise signal attenuation across fiber optic systems. This instrument delivers electronically controlled attenuation with 0.1 dB resolution, supporting both multimode and single mode fiber at multiple wavelengths. Dual control modes - front panel and external voltage - provide operational flexibility for laboratory and field deployment.
Technical Specifications
- Attenuation Range: 0–70 dB at 850 nm and 1300 nm; 0–60 dB at 1550 nm
- Wavelengths: 850 nm, 1300 nm, 1550 nm
- Resolution: 0.1 dB
- Insertion Loss: 3.0 dB (measured)
- Fiber Types: Multimode and Single Mode
- Optical Interface: ST/PC
Key Features
- Digital display with full attenuation and wavelength annunciation
- Front panel manual control or external electrical voltage input (25 dB per volt scale factor)
- Small, lightweight form factor
- AC adapter supplied; internal batteries user-replaceable
Typical Applications
- Shortwave and longwave fiber optic signal testing
- Optical power level characterization across multimode and single mode systems
- Automated test sequences via analog voltage control
- Laboratory and field measurement environments
Compatibility & Integration The 19XT-062T accepts standard ST/PC connectors and operates across common fiber optic wavelengths (850 nm, 1300 nm, 1550 nm), making it compatible with both legacy multimode infrastructure and modern single mode deployments. External control capability enables integration into automated test stations through simple analog voltage signaling.

3M Photodyne 19XT-062T — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the 3M Photodyne 19XT-062T. 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 3M Photodyne 19XT-062T 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.

This 3M Photodyne 19XT-062T is listed at $75. Calibration is available separately from $450. Contact us for volume pricing or if you need multiple units.
3M Photodyne 19XT-062T calibration cost
NIST-traceable calibration for the 3M Photodyne 19XT-062T 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 →
