JDSU TB9226+1SP1 TB9 Tunable Grating Filter, 1460–1575 nm, 0.25 nm Bandwidth, ST/PC Front Bulkheads

The JDSU TB9226+1SP1 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 a desired signal while suppressing amplified spontaneous emission, broadband optical noise, and unwanted spectral content from laser sources.

The TB9226 filter can be controlled across wavelengths from 1460 nm to 1575 nm. Its documented optical performance is optimized within the 1530 nm to 1570 nm C-band window. The optimized specification window should not be confused with the full wavelength range over which the filter can be tuned.

The TB9226+1SP1 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. This configuration uses ST/PC optical connectors with bulkheads mounted on the front panel. The instrument can be operated locally from its front-panel keypad or controlled remotely through IEEE 488 and RS232C interfaces.

Full Wavelength Range and Optimized Performance Window

The JDSU TB9226+1SP1 has a controllable wavelength range from 1460 nm to 1575 nm. This represents the overall wavelength-tuning capability of the instrument.

The documented range from 1530 nm to 1570 nm identifies the C-band window in which the listed insertion-loss, polarization-dependent-loss, and passband specifications are optimized. It does not represent the complete wavelength range over which the filter can be controlled.

When operating between 1460 nm and 1530 nm or between 1570 nm and 1575 nm, the filter remains wavelength adjustable. Users should evaluate the optical response at the intended wavelength to confirm that the available performance meets the requirements of the application.

Narrowband Diffraction Grating Filtering

The JDSU TB9 Series uses a grating-based optical architecture to select a narrow spectral region while rejecting wavelengths outside the desired passband. The design provides stronger wavelength-isolation roll-off than conventional Fabry-Perot etalons or interference filters.

The TB9226 is the narrowest standard model documented for this generation of the 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 response is useful for isolating selected laser wavelengths, reducing broadband optical noise, suppressing spontaneous emission, and improving the spectral definition of a source used for optical component testing.

Amplified Spontaneous Emission Filtering

The JDSU TB9226+1SP1 can be used for amplified spontaneous emission filtering in erbium-doped fiber amplifier applications. EDFAs can produce broadband ASE in addition to the desired amplified signal, potentially increasing measurement noise and affecting wavelength-selective tests.

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

The narrow 0.25 nm nominal passband is useful where strong wavelength selectivity is required. Filter insertion loss, source power, polarization-dependent loss, connector condition, and the sensitivity of the receiving equipment should be considered when configuring the complete test system.

Spontaneous-Emission Suppression for Laser Sources

The TB9226+1SP1 can suppress spontaneous emission from distributed feedback lasers and tunable laser sources. A laser may produce the desired narrow optical carrier together with lower-level spectral content outside the primary wavelength.

By tuning the filter to the laser wavelength, users can reduce unwanted optical 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 wavelength sweeps and channel-based measurements across the filter’s 1460 nm to 1575 nm controllable range.

WDM and DWDM Component Testing

The JDSU TB9226+1SP1 is suitable for wavelength-selective testing of WDM and DWDM components. The filter can isolate the required optical channel before or after the 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, optical spectrum analyzer, optical switch, or variable optical attenuator. This supports wavelength sweeps, channel-by-channel measurements, insertion-loss testing, passband evaluation, and spectral-rejection analysis.

ST/PC Front-Panel Optical Interfaces

The TB9226+1SP1 uses ST/PC optical connectors with bulkheads mounted on the front panel. Compatible ST/PC single-mode patch cords should be used for the filter input and output.

All ST/PC 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.

Patch cords should be routed with appropriate bend-radius control and strain relief. Excessive bending or pulling can affect optical power and measurement repeatability.

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+1SP1 controllable range.

The filter should be connected using clean, compatible single-mode ST/PC 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 limits before the optical source is enabled.

Calibration and Testing Before Shipment

When calibration is technically applicable and supported, the JDSU TB9226+1SP1 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 1460 nm to 1575 nm 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+1SP1 is a configuration-specific tunable grating filter. Buyers should confirm that the 1460 nm to 1575 nm controllable range, 1530 nm to 1570 nm optimized performance window, 0.25 nm nominal passband, ST/PC connectors, and front-panel bulkheads match the intended optical system.

The full wavelength-tuning range and optimized specification window should not be treated as the same value. The filter is controllable from 1460 nm to 1575 nm, while the documented insertion-loss, polarization-dependent-loss, and passband specifications are optimized from 1530 nm to 1570 nm.

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.
