JDS Uniphase TB9223-Z001 C/L-Band 0.6 nm Tunable Optical Grating Filter

JDS Uniphase TB9223-Z001 C/L-Band 0.6 nm Tunable Optical Grating Filter

The JDS Uniphase TB9223-Z001 is a custom tunable optical grating filter designed for wavelength-selective testing across the C-band and L-band. The TB9223 platform supports an extended tuning range from 1525 nm to 1625 nm, allowing one instrument to cover a broad section of the optical spectrum used in telecommunications, amplifier testing, wavelength-division multiplexing, and photonics research.

This unit is identified with a 0.6 nm optical bandwidth. The relatively narrow passband allows the filter to isolate a selected portion of a broadband optical signal while rejecting wavelengths outside the active passband. This makes the TB9223-Z001 useful for wavelength selection, broadband source filtering, optical component characterization, channel isolation, spectral testing, and controlled optical experiments.

The Z001 suffix identifies a custom configuration. The supplied source material confirms that model 223 supports the extended 1525 nm to 1625 nm tuning range, but the custom suffix does not disclose every installed feature. The precise connector type, port arrangement, input-power rating, insertion loss, passband shape, out-of-band rejection, tuning resolution, polarization performance, and other unit-specific characteristics should be verified from the instrument label, calibration records, or functional test results.

1525 nm to 1625 nm C/L-Band Tuning

The TB9223 platform supports a tuning range from 1525 nm to 1625 nm. This extended wavelength span covers the C-band and L-band regions used in optical communications, wavelength-division multiplexing, optical amplification, and component testing.

The broad tuning range allows the filter to be adjusted across approximately 100 nm without replacing the optical filter or rebuilding the measurement path. This is useful when a device must be evaluated at several wavelengths or when a broadband source must be converted into a wavelength-selective test signal.

The selected wavelength must remain compatible with the connected source, detector, patch cords, adapters, and device under test. The complete optical system should be evaluated at the wavelengths required by the application.

0.6 nm Optical Bandwidth

The TB9223-Z001 is identified with a 0.6 nm optical bandwidth. This bandwidth describes the wavelength interval passed by the filter around its selected center wavelength.

A 0.6 nm passband can isolate a comparatively narrow portion of a broadband optical spectrum. The filtered signal can then be applied to a wavelength-sensitive component, amplifier, detector, receiver, or experimental system.

The precise definition of the stated 0.6 nm bandwidth, including the measurement level used to specify the passband, is not provided in the available source material. The bandwidth should therefore be verified with an optical spectrum analyzer when formal spectral characterization is required.

Actual transmitted bandwidth and passband shape can depend on wavelength, tuning position, source spectrum, polarization, optical power, connector condition, and the individual custom configuration.

Tunable Optical Grating Filter Technology

The TB9 Series uses an optical grating filter to select a wavelength region from an incident optical signal. The grating-based design provides wavelength-selective transmission that can be adjusted across the supported tuning range.

Unlike a fixed filter, the tunable design allows one instrument to address multiple wavelengths. This can simplify laboratory setups involving broadband sources, optical spectrum analyzers, amplifiers, detectors, and wavelength-dependent devices.

The TB9223-Z001 is a passive optical filtering instrument. It does not generate optical power, amplify the input signal, or independently measure the transmitted wavelength or optical power. A compatible source and measurement instrument are required to create a complete test system.

Broadband Source Filtering

The TB9223-Z001 can be connected to a compatible broadband optical source to create a wavelength-selective output. The filter transmits the selected spectral region while reducing optical power outside the active passband.

Compatible broadband sources may include amplified spontaneous emission sources and other optical sources that cover the wavelength region of interest. The source must provide sufficient spectral power density at the selected wavelength after accounting for filter loss and other components in the optical path.

A compatible optical spectrum analyzer can be used to observe the filtered spectrum, confirm the center wavelength, measure the transmitted bandwidth, and evaluate unwanted out-of-band signals.

C-Band Component Characterization

The lower portion of the 1525 nm to 1625 nm tuning range covers the C-band region used by many dense wavelength-division multiplexing systems and erbium-doped fiber amplifiers.

The filter can support characterization of C-band couplers, splitters, isolators, circulators, optical switches, attenuators, filters, multiplexers, demultiplexers, detectors, and other wavelength-dependent components.

Testing can be performed by tuning the filter to selected wavelengths and measuring the optical response of the device under test. The measurement procedure should include an appropriate reference spectrum so the filter, source, and external path are separated from the response of the device.

L-Band Component Characterization

The upper portion of the tuning range extends through the L-band to 1625 nm. This supports testing of long-wavelength optical components, extended-band amplifiers, monitoring systems, and telecommunications equipment.

The extended range is particularly useful for devices whose transmission or loss must be evaluated beyond the conventional C-band. One filter can be used for measurements across both bands, reducing the need for separate wavelength-specific instruments.

The optical source and receiving instrument must provide adequate coverage and sensitivity throughout the selected L-band range.

Optical Amplifier Testing

The TB9223-Z001 can be incorporated into compatible optical amplifier test systems. A broadband source can be filtered to produce a selected optical band for evaluating amplifier gain, wavelength response, saturation behavior, and output characteristics.

The 1525 nm to 1625 nm tuning range supports work with compatible C-band and L-band optical amplifiers. Additional optical power meters, spectrum analyzers, attenuators, switches, couplers, and isolators may be required for a complete amplifier measurement setup.

Input and output optical power levels must remain within the supported ratings of the filter, amplifier, and every connected instrument. The custom unit’s input-power rating should be confirmed before high-power optical signals are applied.

WDM and DWDM Testing

The tunable passband can support wavelength-selective testing of WDM and DWDM components. A selected spectral region can be passed through the device under test while a compatible optical instrument measures transmission, loss, isolation, or spectral response.

Typical devices include optical filters, wavelength-selective couplers, multiplexers, demultiplexers, add-drop devices, switches, and monitoring components.

The 0.6 nm bandwidth should be considered in relation to the channel spacing and spectral response of the device under test. A passband wider than the tested channel may include adjacent spectral content, while a narrower device passband may shape the filtered output.

Measurement Setup and Referencing

A compatible broadband optical source should be connected to the filter input, and an optical spectrum analyzer or suitable wavelength-selective detector should be connected to the output. The source must cover the wavelength selected on the filter.

A reference spectrum should be measured through the intended optical path before the device under test is inserted. The reference and measurement should use the same source, analyzer settings, resolution bandwidth, patch cords, connector interfaces, and optical power levels.

The filter should then be tuned to the desired center wavelength. The output spectrum can be used to confirm the selected wavelength, transmitted bandwidth, insertion loss, passband shape, and out-of-band response.

When the filter is used with high optical power, the output should be measured or attenuated before connection to sensitive detectors or analyzers.

Connector Inspection and Cleaning

Every optical connector should be inspected and cleaned before use. Contamination can increase insertion loss, produce unwanted reflections, distort the measured spectrum, and damage the optical interfaces.

The connector type and ferrule polish must match the connected patch cord. APC and non-angled physical-contact connectors should not be directly intermated.

Protective caps should remain installed whenever the ports are not in use. Dust caps should also be kept clean so they do not transfer contamination to the optical interfaces.

Comprehensive Functional and Performance Testing

The JDS Uniphase TB9223-Z001 receives comprehensive functional and performance testing before shipment. Evaluation may include tuning-control operation, mechanical response, wavelength selection, optical continuity, and inspection of the installed connector or pigtail interfaces.

Optical testing may include verification of transmission at representative C-band and L-band wavelengths, center-wavelength tuning across the supported 1525 nm to 1625 nm range, confirmation of the identified 0.6 nm bandwidth, insertion-loss comparison, passband evaluation, and out-of-band response when suitable equipment is available.

The optical ports, connectors, pigtails, controls, enclosure, labels, and mechanical components may be inspected for contamination, damage, wear, or conditions that could affect tuning and optical transmission.

The exact testing scope depends on the installed input-power option, connector configuration, available broadband source, calibrated wavelength meter, optical power meter, optical spectrum analyzer, and requested test points.

Calibration Before Shipment

When technically applicable and selected, the JDS Uniphase TB9223-Z001 can be calibrated or performance-verified before shipment. Evaluation may include center-wavelength accuracy, tuning range, optical bandwidth, insertion loss, spectral shape, and out-of-band response at selected C-band and L-band wavelengths.

Calibration should use compatible traceable wavelength and optical power measurement equipment. Test documentation should identify the filter model and serial number, connector configuration, source, input power, center-wavelength settings, analyzer resolution bandwidth, recorded spectral measurements, and environmental conditions.

Buyers requiring formal calibration should specify the desired C-band and L-band wavelengths, bandwidth measurement method, optical power levels, connector configuration, certificate type, recorded results, and required measurement uncertainty before purchase.
