This unit
The Santec OTF-950 is a bench-top tunable optical filter engineered for precision wavelength selection in optical communication and measurement systems. It delivers independent, simultaneous control of wavelength tuning and passband width across the C-band and extended infrared range. The instrument employs free-space optics and precision tuning mechanics to achieve flat-top passband characteristics with excellent optical control.
A 40 nm tuning range and wavelength accuracy of ±0.02 nm enable reliable channel selection and spectral analysis. The OTF-950 interfaces via USB with LabVIEW software support and GPIB for remote operation, accommodating both manual and automated wavelength and bandwidth configuration. Insertion loss of approximately 5 dB with 0.5 dB uniformity, combined with low PDL (≤ 0.25 dB) and PMD (≤ 0.2 ps), ensures minimal signal degradation across polarization states.
Return loss exceeds 45 dB. Though Santec has discontinued manufacturer support, the OTF-950 remains operational for legacy installations and applications requiring flexible optical filtering.

Santec OTF-950 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Santec OTF-950. 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 Santec OTF-950 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.
