JDSU BBS1590+1FP L-Band Broadband Optical Source, 1565–1605 nm, FC/HPC

JDSU BBS1590+1FP L-Band Broadband Optical Source, 1565–1605 nm, FC/HPC

The JDSU BBS1590+1FP is a high-power broadband optical source designed for wavelength-dependent testing of single-mode fiber optic components, subsystems, and communication equipment. This BBS1590 configuration operates across the L-band from 1565 nm to 1605 nm and provides a gain-flattened optical spectrum for laboratory, research, development, engineering, and production applications.

The broadband source delivers more than 10 dBm of total fiber-coupled optical power. Typical spectral density is greater than -5 dBm/nm, while typical spectral uniformity is maintained within ±1 dB. This combination provides broad optical coverage for testing devices whose performance varies with wavelength.

The BBS1590+1FP uses an FC/HPC optical output and is housed in a compact half-rack benchtop enclosure. Its broad L-band spectrum can be used with compatible optical spectrum analyzers, power meters, wavelength-selective measurement systems, switches, attenuators, and devices under test.

L-Band Broadband Optical Output

The JDSU BBS1590 is designed for optical testing across the 1565 nm to 1605 nm L-band wavelength range. Unlike a fixed-wavelength laser, the broadband source emits optical energy across a continuous spectrum, allowing compatible receiving equipment to evaluate the wavelength-dependent response of an optical component.

This broadband approach can reduce the need to step a narrow-linewidth source through many individual wavelengths. A compatible optical spectrum analyzer or wavelength-resolved measurement system can observe the response of the device under test across the available spectrum.

The BBS1590 uses a gain-flattened output to maintain more consistent spectral power across the L-band. Typical spectral uniformity is less than ±1 dB, helping support comparative measurements across the documented wavelength range.

High Optical Power and Spectral Density

The BBS1590+1FP provides total optical power greater than 10 dBm. This corresponds to more than 10 mW of total fiber-coupled output distributed across the broadband spectrum.

Typical spectral density is greater than -5 dBm/nm. Spectral density is important when selecting a compatible detector or analyzer because broadband optical power is distributed across wavelength rather than concentrated at one narrow optical frequency.

The optical power reaching the device under test depends on the source output, patch-cord loss, connector condition, splitting ratio, external attenuation, filter loss, and wavelength response of the complete optical path.

Optical Component Spectral Testing

The JDSU BBS1590+1FP can provide broadband illumination for characterizing passive and active optical components. The source is connected to the device under test, while compatible measurement equipment observes the transmitted, reflected, or distributed optical spectrum.

This configuration can support wavelength-dependent evaluation of filters, splitters, couplers, gratings, multiplexers, demultiplexers, optical amplifiers, and other components intended for L-band systems.

The broadband source generates the optical spectrum but does not independently analyze the resulting signal. A compatible optical spectrum analyzer, detector system, or wavelength-resolved measurement instrument is required to obtain spectral measurement results.

Typical Applications

The JDSU BBS1590+1FP Broadband Source is suitable for professional applications such as:

• L-band optical component spectral testing
• WDM and DWDM component characterization
• Optical filter evaluation
• MUX and DEMUX testing
• Fiber Bragg grating characterization
• Optical coupler and splitter analysis
• Wavelength-dependent insertion-loss testing

FC/HPC Optical Output

The JDSU BBS1590+1FP uses an FC/HPC optical output. Compatible straight-contact FC single-mode patch cords should be used when connecting the source to a device under test or optical measurement system.

FC/HPC and FC/APC connectors use different end-face geometries and should not be mated directly. The connector polish and key configuration should be verified before connection.

All fiber connector end faces should be inspected and cleaned before mating. Contamination can reduce transmitted optical power, increase backreflection, affect spectral uniformity, and transfer debris to the source output interface.

Measurement Preparation

The broadband source should be allowed to stabilize before precision spectral measurements. The optical output should remain protected or connected to a compatible optical path whenever the source is enabled.

Receiving equipment should support the 1565 nm to 1605 nm operating range and the available optical power. External attenuation or optical splitting may be required to protect sensitive detectors or distribute the source across multiple measurement paths.

Patch cords should remain stationary during reference and measurement procedures. Fiber movement, connector contamination, temperature changes, and optical backreflection can affect measured power and spectral response.

Calibration and Testing Before Shipment

When calibration is technically applicable and supported, the JDSU BBS1590+1FP is calibrated before shipment. The calibration process may include verification of operating wavelength range, total optical output power, spectral density, spectral uniformity, output stability, isolation, and FC/HPC optical interface performance.

Following successful calibration, the instrument may include a calibration label, calibration certificate, and related calibration data, depending on the equipment configuration and calibration service.

If formal calibration is unavailable or not applicable to the specific instrument, the unit receives comprehensive functional and performance testing. This process may include broadband optical output verification, spectral-response evaluation, output-stability testing, connector inspection, power-control checks, indicator operation, and basic electrical testing.

This testing helps verify that the equipment operates correctly and that its available functions have been evaluated before it is released for shipment. The exact calibration scope, documentation, spectral data, test results, and service records should be confirmed before purchase when these items are required for laboratory, production, regulatory, or quality-management applications.

Buyer Considerations

The JDSU BBS1590+1FP is specifically an L-band broadband source. Buyers should confirm that the 1565 nm to 1605 nm operating range, greater than 10 dBm total optical output, FC/HPC interface, spectral density, and typical spectral uniformity match the intended measurement requirements.

The BBS1590 should not be confused with the BBS1550 C-band source, the BBS1560 C+L-band source, or later BBS1590 configurations documented with different wavelength limits and output-power specifications. This description applies specifically to the configuration and documentation associated with the BBS1590+1FP model.

Buyers should review the physical condition, FC/HPC output interface, optical output, spectral performance, cooling, indicators, calibration status, and included accessories before purchase. Only items specifically identified in the listing should be considered included.
