This unit
The Santac OTF-920 is a programmable optical tunable bandpass filter that delivers precise wavelength selection and signal filtering across the C-band telecommunications window. Built on multilayer dielectric interference filters and Santec's patented linear sliding tuning method, it maintains stable bandwidth, insertion loss, and polarization dependent loss across its entire tuning range. The dual-slider configuration enables independent control of two optical channels, supporting continuous 80 nm tuning, split-band operation, or combined wavelength and power management through integrated variable attenuators.

Santac OTF-920 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Santac OTF-920. 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 Santac OTF-920 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.
