This unit
The JDS Uniphase HA027+20ASU1 is a programmable optical attenuator that delivers precise, stable reduction of optical signal power across telecommunications and test wavelengths. It combines a wide 100 dB attenuation range with 0.01 dB resolution and ±0.1 dB accuracy, making it suitable for power meter calibration, BER testing, system characterization, and laboratory measurements where signal level control must be both accurate and repeatable.
Technical Specifications
- Attenuation Range: Up to 100 dB
- Resolution: 0.01 dB nominal
- Accuracy: ±0.1 dB
- Repeatability: 0.01 dB
- Wavelength Range: 1200–1700 nm (standard); optional 750–1700 nm available (60 dB range)
- Wavelength Dependence: 60 dB
- Insertion Loss: ~1.53 dB at 1550 nm (0 dB attenuation setting, including connector loss)
- Fiber Type: Single-mode 9/125 µm
- Connectors: SC/APC
Key Features
- SCPI/HP8156A-compatible command set for instrument integration
- Dual remote control interfaces: GPIB (IEEE 488.2) and RS232
- Front-panel keypad control
- Built-in beam block for rapid infinite attenuation (>90 dB)
- Minimal cavity effects and discrete internal reflections <60 dB
- Class 1 instrument with CE, UL3101-1, and CAN/CSA-C22.2 No. 1010.1 compliance
Typical Applications
- Optical power meter linearity verification
- Bit error rate (BER) characterization
- Loss simulation in fiber-optic links
- EDFA output power assessment
- Amplifier and DWDM system testing
- Analog transmission and multichannel AM evaluation
- High bit-rate PCM and CATV AM systems
Compatibility & Integration Optional couplers (2/98, 10/90, 30/70, 50/50) and 1:2 switches can be integrated. When a switch is installed, the 5V output may not be externally available.

JDS Uniphase/JDSU HA027+20ASU1 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the JDS Uniphase/JDSU HA027+20ASU1. 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 JDS Uniphase/JDSU HA027+20ASU1 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.
