JDSU HA9508-FPL2 HA9W 9/125 Single-Mode Optical Attenuator with FC/PC Front Bulkheads

The JDSU HA9508-FPL2 HA9W Optical Attenuator is a professional HA Series fiber optic attenuator configured for single-mode optical test, telecom, laboratory, production, and photonics applications. This product description applies specifically to the HA9508-FPL2 configuration and uses only the configuration details identified for this exact device.

The HA9508-FPL2 configuration uses 9/125 single-mode fiber, no built-in option, the HA9W wide wavelength range model covering 750 nm to 1700 nm, FC/PC connector configuration, low backreflection, and front-panel bulkheads. These configuration details are important for buyers replacing an existing attenuator or matching a specific optical test setup where fiber type, wavelength range, connector style, port layout, and backreflection option must be correct.

Features and Benefits of the JDSU HA9508-FPL2 HA9W Optical Attenuator

The JDSU HA9508-FPL2 HA9W Optical Attenuator provides practical value for professional users who require a clearly defined single-mode optical attenuation configuration for fiber optic measurement and test workflows.

• HA9W wide wavelength model: Uses the HA9W model configuration, identified for 750 nm to 1700 nm optical attenuation applications.
• 9/125 single-mode fiber: Configured for 9/125 single-mode fiber optic test and measurement environments.
• FC/PC connector configuration: Uses FC/PC connectors for compatible single-mode optical patching and test setups.
• Front-panel bulkheads: Uses the front-panel bulkhead port configuration for convenient direct access to the optical connections.
• No built-in option: This HA9508-FPL2 configuration does not include a built-in splitter, coupler, or 1:2 switch option.
• Low backreflection configuration: Uses the low backreflection option for the configured HA9W attenuator.
• Wide attenuation coverage: Provides controlled attenuation across 750 nm to 1700 nm, with range dependent attenuation performance across the specified wavelength bands.

Advanced Features and Practical Applications

The JDSU HA9508-FPL2 is intended for optical test environments where controlled single-mode attenuation is required across a wide 750 nm to 1700 nm wavelength range. Optical attenuators are commonly used to reduce optical signal power to defined test levels during receiver sensitivity testing, optical link simulation, calibration procedures, system verification, and optical component characterization.

The HA9W model is designed for broad wavelength use and supports 100 dB attenuation from 750 nm to 1500 nm and 60 dB attenuation from 1500 nm to 1700 nm. This makes the HA9508-FPL2 useful for single-mode test applications where both wide wavelength coverage and controlled attenuation are required. The 9/125 fiber configuration supports single-mode optical workflows, while the FC/PC connector configuration provides a defined connection interface for compatible patch cables, optical sources, meters, receivers, and test equipment.

The front-panel bulkhead configuration is practical for bench-top, rack-based, and laboratory optical test systems where direct access to the optical ports is useful. This front-panel layout can help simplify patching, troubleshooting, receiver testing, component characterization, and general optical power adjustment during everyday test workflows.

Because HA Series optical attenuators can be configured in many different ways, this listing should be used only for HA9508-FPL2. Other HA Series model numbers may use different wavelength ranges, fiber types, built-in options, connectors, backreflection settings, or port layouts. Matching the exact configuration is important for maintaining compatibility with existing test procedures and optical setups.

Optical Attenuator Applications

The JDSU HA9508-FPL2 HA9W Optical Attenuator can be used in professional single-mode optical test environments where controlled signal attenuation is required across a wide 750 nm to 1700 nm wavelength range. This type of attenuator is commonly used to set optical power levels, simulate fiber link loss, support receiver sensitivity testing, and help characterize optical components under repeatable test conditions.

With its 9/125 single-mode fiber configuration, 750 nm to 1700 nm wavelength range, FC/PC connector configuration, low backreflection option, and front-panel bulkhead layout, this configuration is intended for users who need the exact HA9508-FPL2 setup. The front bulkhead arrangement can be useful in bench-top or rack-based systems where direct access to the optical ports is preferred.

In a professional optical test bench, the attenuator can be positioned between an optical source and a device under test to reduce signal level to a controlled value. The defined HA9508-FPL2 configuration helps support repeatable single-mode measurement workflows where exact connector, fiber, wavelength range, attenuation range, and port configuration are important.

The FC/PC connector interface should be matched to compatible FC/PC patch cords and mating adapters. Proper connector cleaning and inspection are important before connection because contaminated fiber interfaces can affect attenuation accuracy, insertion loss, backreflection performance, and repeatability in optical measurement systems.

Compatibility and Configuration Notes

The HA9508-FPL2 part number should be reviewed carefully before purchase because each section of the model number identifies a specific configuration. For this unit, the configuration is 9/125 single-mode fiber, no built-in option, 750 nm to 1700 nm model range, FC/PC connector type, low backreflection, and front-panel bulkheads. These attributes should be matched against the buyer’s existing patch cords, optical source, receiver, power meter, and test procedure requirements.

This configuration is intended for single-mode optical test environments. Buyers replacing an existing unit should verify the fiber type, connector polish, port location, wavelength range, and attenuation range requirements to avoid ordering a unit that does not match the existing measurement setup.

Connector compatibility is especially important for optical attenuators. The FC/PC connector type should be used only with compatible FC/PC patch cables and mating interfaces. Users should follow proper fiber cleaning and inspection practices before connection to help protect optical interfaces and maintain repeatable measurement performance.

Buyer Considerations

The JDSU HA9508-FPL2 is a configuration-specific optical attenuator. Buyers should confirm that the HA9W 750 nm to 1700 nm model range, 9/125 single-mode fiber type, FC/PC connector configuration, low backreflection option, and front-panel bulkhead port layout match the intended optical test setup before purchase.

Buyers should also review the product condition, included accessories, connector condition, calibration or service notes, and any installed options before purchase. If the attenuator is being integrated into an existing rack, bench, or automated test station, the port layout and connector style should be confirmed against the current cabling and instrument configuration.

This description applies only to the HA9508-FPL2 configuration. It should not be used for other HA Series attenuators with different model numbers, fiber types, wavelength ranges, connector types, port arrangements, backreflection options, or built-in options.
