JDS Uniphase HA9108-SPL2

The JDS Uniphase HA9108-SPL2 is a programmable optical attenuator for precise control of optical signal power in multimode fiber networks. It delivers attenuation across 750–1700 nm with variable range depending on wavelength band, ±0.15 dB accuracy, and remote control via GPIB or RS232. Designed for telecommunications and data center applications where signal integrity and repeatable attenuation are critical.

## Technical Specifications

• SCPI/HP8156A compatible command set enables seamless integration with existing test platforms
• Low insertion loss (40 dB) ensures minimal reflections back to the source
• Wavelength-dependent attenuation supports broadband optical testing from near-IR through C-band and into L-band

## Typical Applications

• Optical power level control in telecommunications test benches
• Data center optical link characterization and validation
• Multimode fiber network attenuation simulation
• Equipment performance testing under controlled signal conditions

## Compatibility & Integration

The HA9108-SPL2 integrates into automated test systems via GPIB or serial control. Its SCPI command syntax aligns with HP8156A instruments, reducing setup time in multi-vendor environments. Front panel control supports standalone operation for manual adjustments during development and troubleshooting.
