When accuracy matters in 400G/800G transceiver validation, coherent DWDM system testing, or OSNR measurements, the EXFO OSA20 Optical Spectrum Analyzer is a critical tool in the lab. If your OSA20 starts producing unstable traces, wavelength shifts, or software errors, Aumictech is here to restore it with certified repair and NIST-traceable calibration.
We provide complete support for EXFO’s latest-generation OSA20, trusted across global networks and photonics R&D labs for its speed, spectral fidelity, and wide measurement range.
About the EXFO OSA20 Optical Spectrum Analyzer
The EXFO OSA20 is a modern, field-ready yet lab-capable spectrum analyzer that blends performance with portability — making it ideal for network equipment vendors, transceiver manufacturers, and carrier-grade testing.
Key features include:
- Wavelength range: 1250 – 1650 nm
- Support for 400G and 800G transceivers (NRZ/PAM4)
- Built-in OSNR testing without modulation shutdown
- Up to 90 dB dynamic range
- 50 GHz, 100 GHz, and flexible resolution bandwidth
- Real-time coherent signal analysis
- High-speed sweep and low noise floor
It’s used in next-gen telecom, data center interconnect, and high-speed optical module validation, making it one of the most in-demand OSAs in 400G/800G and beyond.
What Can Go Wrong – EXFO OSA20 Issues We Fix
Despite being modern and robust, the OSA20 is a sensitive precision instrument. Common problems that affect performance include:
🔧 Wavelength Inaccuracy or Drift
- Caused by environmental fluctuations, internal aging components, or reference calibration drift
- We restore wavelength accuracy using NIST-traceable laser standards
🔧 No Signal Detected or Low Dynamic Range
- Can result from faulty detectors, dirty optical inputs, or degraded internal optics
- We test photodetectors, replace front-end modules, and recalibrate power levels
🔧 Firmware or GUI Freezes
- May be related to storage faults, firmware corruption, or system software bugs
- We update firmware, reset internal memory, and verify all software modules
🔧 OSNR Measurement Errors
- If built-in OSNR values seem unstable or inaccurate
- We perform full validation of the built-in EDFA simulation and resolution bandwidth functions
🔧 Power Supply or Thermal Issues
- Overheating or unstable power sources can affect baseline noise and accuracy
- We replace cooling fans, test regulators, and stabilize internal electronics
After any repair, Aumictech performs a complete sweep validation across multiple channels and fiber types to ensure consistent, repeatable results.
Full Calibration Service – NIST-Traceable and Industry Compliant
At Aumictech, we perform comprehensive calibration for EXFO OSA20 units using precision optical references, tunable lasers, and traceable test standards. Calibration includes:
- ✔️ Wavelength accuracy (calibrated with gas cells and narrow-line lasers)
- ✔️ Power level linearity verification across 1250–1650 nm
- ✔️ Resolution bandwidth accuracy (50/100 GHz + custom settings)
- ✔️ Noise floor and SNR validation
- ✔️ OSNR algorithm consistency across modulation types
- ✔️ Sweep speed testing and stability checks
- ✔️ Test port performance and reflection loss
- ✔️ Polarization effect testing (if enabled)
Each unit is returned with a detailed digital certificate that includes:
- Pre- and post-calibration data
- Test conditions and equipment used
- Traceability documentation to NIST standards
- Calibration date and recommended due date
