JDSU TB9226+1FP1 TB9 C-Band Tunable Grating Filter with FC/HPC Front Bulkheads

JDSU TB9226+1FP1 TB9 C-Band Tunable Grating Filter with FC/HPC Front Bulkheads

The JDSU TB9226+1FP1 is a programmable diffraction grating filter designed for high-performance laboratory and production testing of single-mode fiber optic components and subsystems. It provides wavelength-selective optical filtering for isolating desired signals while suppressing amplified spontaneous emission, broadband optical noise, and unwanted spectral content from laser sources.

This configuration uses the narrowband TB9226 filter model with the C-band wavelength option, FC/HPC optical connectors, and front-panel bulkheads. Optical performance is optimized from 1530 nm to 1570 nm, while the filter can be controlled across a broader wavelength range from 1460 nm to 1575 nm.

The TB9226+1FP1 provides a nominal -3 dB bandwidth of 0.25 nm, a nominal -20 dB bandwidth of 0.7 nm, and wavelength adjustment with 0.01 nm resolution. The filter can be operated from its front-panel keypad or controlled remotely through IEEE 488 and RS232C interfaces for integration into automated optical measurement systems.

Narrowband Diffraction Grating Filter

The JDSU TB9 Series uses a grating-based optical architecture to select a narrow spectral region while rejecting wavelengths outside the desired passband. The filter design is available in single-pass and double-pass grating configurations to support narrow bandwidth and high rejection.

The TB9226 is the narrowest standard filter model documented for this TB9 Series. It provides a nominal -3 dB bandwidth of 0.25 nm and a nominal -20 dB bandwidth of 0.7 nm. Both bandwidth values have a tolerance of ±15%.

This narrow optical response is useful for isolating individual channels, suppressing broadband noise, and separating a selected laser wavelength from surrounding spontaneous-emission content. Actual performance can also be influenced by wavelength, polarization, temperature, connector condition, source characteristics, and calibration status.

C-Band Optical Performance

The TB9226+1FP1 is configured with wavelength-range code 1, identifying the C-band version optimized from 1530 nm to 1570 nm. Within this range, insertion loss is specified at 6.0 dB and polarization-dependent loss is specified at 0.2 dB.

The filter can be controlled across wavelengths from 1460 nm to 1575 nm, allowing users to position the passband beyond the primary 1530 nm to 1570 nm specification window when required. Optical performance outside the optimized C-band window should be evaluated according to the needs of the particular application.

Wavelength repeatability is specified at 0.05 nm, while wavelength accuracy is specified at 0.2 nm. The 0.01 nm resolution supports fine incremental adjustment of the selected filter wavelength.

Amplified Spontaneous Emission Filtering

The JDSU TB9226+1FP1 can be used for amplified spontaneous emission filtering in erbium-doped fiber amplifier systems. EDFAs can produce broadband ASE in addition to the desired amplified optical signal. This unwanted spectral energy can interfere with accurate optical measurements and component characterization.

The grating filter can be tuned to pass the desired wavelength while rejecting surrounding ASE. This supports amplifier gain measurements, wavelength-dependent testing, source cleanup, and evaluation of components positioned after an optical amplifier.

The narrow 0.25 nm nominal passband is particularly useful where selective filtering and strong rejection are required. The filter insertion loss, input power, polarization dependence, and connector characteristics should be considered when configuring the complete measurement system.

Spontaneous-Emission Suppression for Laser Sources

The JDSU TB9226+1FP1 can also suppress spontaneous emission from distributed feedback lasers and tunable laser sources. Laser output may contain a desired narrow carrier together with lower-level optical energy outside the primary wavelength.

By tuning the grating filter to the laser wavelength, users can reduce unwanted spectral content before the signal reaches a wavelength-selective component, optical detector, receiver, or other device under test.

For tunable-laser-based measurements, the filter wavelength can be coordinated with the source through the IEEE 488 or RS232C interface. This enables automated channel selection and wavelength sweeps across the available operating range.

WDM and DWDM Component Testing

The JDSU TB9226+1FP1 is suitable for wavelength-selective testing of WDM and DWDM components. The filter can help isolate the required optical channel before or after a device under test.

Typical devices may include optical filters, multiplexers, demultiplexers, wavelength-selective switches, couplers, fiber Bragg gratings, arrayed waveguide gratings, optical amplifiers, and other active or passive photonic components.

The filter can be coordinated with a compatible tunable laser, optical power meter, spectrum analyzer, optical switch, or variable attenuator. This supports channel-by-channel measurements, wavelength sweeps, insertion-loss testing, passband evaluation, and spectral-rejection analysis.

FC/HPC Front-Panel Optical Interfaces

The TB9226+1FP1 uses FC/HPC connectors with optical bulkheads mounted on the front panel. Compatible straight-contact FC single-mode patch cords should be used for the filter input and output.

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 connecting the filter to a laser source, device under test, optical amplifier, or power meter.

All optical connector end faces should be inspected and cleaned before mating. Contamination can increase insertion loss, reduce return loss, introduce measurement instability, and affect the measured filter response.

Measurement Preparation

The desired wavelength should be selected through the front-panel keypad or remote interface before beginning the measurement. Users should verify that the selected wavelength and optical source fall within the TB9226+1FP1 tuning and optimized-performance ranges.

The filter should be connected using clean, compatible single-mode patch cords. Fiber movement, connector contamination, polarization changes, and temperature variation can affect insertion loss, wavelength response, and repeatability.

The complete optical setup should be evaluated for source power, connector compatibility, insertion loss, detector sensitivity, and device-under-test limitations before the source is enabled.

Calibration and Testing Before Shipment

When calibration is technically applicable and supported, the JDSU TB9226+1FP1 is calibrated before shipment. The calibration process may include verification of wavelength accuracy, wavelength repeatability, tuning resolution, passband width, insertion loss, polarization-dependent loss, front-panel operation, and remote-interface control.

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 wavelength tuning across the available range, optical transmission checks, filter-response evaluation, connector inspection, keypad operation, display functions, IEEE 488 communication, and RS232C control.

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, test data, 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 TB9226+1FP1 is a configuration-specific tunable grating filter. Buyers should confirm that the C-band optimized range, broader 1460 nm to 1575 nm tuning capability, 0.25 nm nominal passband, FC/HPC connectors, and front-panel bulkheads match the intended optical system.

The TB9226+1FP1 should not be confused with later TB90226 configurations that may use different part-number structures, documented passband values, wavelength-range codes, or optical options. This description applies specifically to the TB9226+1FP1 configuration documented for the earlier TB9 Series.

Buyers should review the optical connector condition, wavelength-tuning operation, filter transmission, front-panel controls, IEEE 488 and RS232C interfaces, calibration status, service history, and included accessories before purchase.
