Yokogawa AQ2200-111 1310 nm 10 mW DFB Laser Source Module with FC/APC Output and External Modulation

Yokogawa AQ2200-111 1310 nm 10 mW DFB Laser Source Module

The Yokogawa AQ2200-111 is a distributed feedback laser source module designed for installation in a compatible AQ2200 Series Multi Application Test System frame controller. This configuration provides a nominal 1310 nm optical output, a 10 mW output-power option, single-mode fiber, an FC angled physical-contact connector, and external modulation capability.

The AQ2200-111 is designed as a stable reference light source for optical device measurements and fiber optic transmission testing. Its DFB laser architecture provides narrow spectral output with controlled wavelength performance and a side-mode suppression ratio of at least 30 dB for the documented 1310 nm configuration.

The module includes internal optical attenuation over a 10 dB range with 0.01 dB setting steps. This allows the optical level to be adjusted without requiring an external variable attenuator for every measurement configuration.

The AQ2200-111 is a modular source and does not operate as a standalone instrument. A compatible Yokogawa AQ2201 or AQ2202 frame controller is required to provide power, front-panel control, display functions, system communication, and access to the module’s wavelength, output, attenuation, and modulation settings.

1310 nm Distributed Feedback Laser

The AQ2200-111 uses a distributed feedback laser diode to provide narrow spectral output near 1310 nm. This wavelength is widely used for single-mode telecommunications, fiber optic component characterization, receiver testing, transmission experiments, and optical network development.

DFB laser technology provides better longitudinal-mode control than a conventional Fabry-Perot source. The AQ2200-111 specifies a side-mode suppression ratio of at least 30 dB for the 1310 nm configuration, supporting applications requiring a well-defined optical carrier.

The module’s wavelength accuracy is documented within ±0.05 nm at 1310 nm. Wavelength setting resolution is 0.001 nm, allowing fine control through the compatible AQ2200 frame controller.

10 mW Optical Output

The P10 option identifies a 10 mW optical output configuration. An optical power of 10 mW corresponds to approximately +10 dBm.

This output level provides useful optical power for testing passive fiber components, receivers, switches, filters, couplers, splitters, patch cords, and other compatible single-mode devices.

The actual power delivered to a device under test depends on the module setting, internal attenuation, connector condition, patch-cord loss, external optical components, and the measurement reference plane. A calibrated optical power meter should be used when the exact delivered level must be documented.

Internal Optical Attenuation

The AQ2200-111 provides an internal optical attenuation range of 10 dB. Attenuation can be adjusted in 0.01 dB steps through the compatible AQ2200 frame controller.

Internal attenuation allows source power to be reduced without repeatedly changing external optical components. This is useful for receiver sensitivity testing, component characterization, comparative measurements, and procedures requiring several controlled optical levels.

The attenuator setting should be verified together with the measured output power when traceable optical levels are required. External patch cords, adapters, and devices can introduce additional loss beyond the module’s internal attenuation setting.

External Modulation Capability

This AQ2200-111 configuration includes external modulation capability. External modulation allows a compatible electrical control signal to vary or switch the optical output for supported measurement applications.

Yokogawa offered sine-wave and chopped external modulation configurations within the AQ2200-111 ordering structure. The exact installed external modulation option should be confirmed from the complete module option code or physical identification label.

The external modulation input should only be driven with a signal that meets the electrical and frequency requirements of the installed modulation option. Unsupported waveform type, voltage, offset, or frequency can cause incorrect operation or damage.

Single-Mode Fiber Configuration

The SMF option identifies a single-mode fiber configuration. The module is intended for use with compatible single-mode patch cords and optical devices.

Maintaining single-mode fiber throughout the optical path helps preserve the intended launch condition and measurement repeatability. Multimode patch cords should not be substituted when precision single-mode measurements are required.

Fiber patch cords should be protected from tight bends, pulling, twisting, crushing, and repeated movement. Mechanical changes in the fiber path can affect optical power and measurement stability.

FC/APC Optical Output

The FCA configuration identifies an FC angled physical-contact optical connector. The angled ferrule helps reduce reflected light at a properly mated connection.

Compatible FC/APC single-mode patch cords should be used with the module. FC/PC and FC/APC connectors must not be directly intermated because their ferrule geometries are incompatible.

The module output and mating patch cord should be inspected and cleaned before connection. Contamination can increase insertion loss, reduce return loss, destabilize the source, and damage both connector end faces.

AQ2200 Series Frame Compatibility

The AQ2200-111 requires a compatible AQ2200 Series frame controller. Supported frame platforms include the AQ2201 three-slot frame controller and the AQ2202 nine-slot frame controller.

The frame supplies operating power and provides the color display, local controls, module recognition, storage functions, system software, and remote interfaces required to operate the source.

The modular platform allows the DFB source to be combined with optical power sensors, attenuators, switches, tunable sources, modulators, and other compatible AQ2200 modules according to the measurement application.

Automated Optical Testing

A compatible AQ2200 frame can support remote control through Ethernet and GPIB. This allows the AQ2200-111 to be incorporated into automated laboratory, production, and qualification systems.

Automated systems can coordinate the source with compatible optical power meters, attenuators, switches, spectrum analyzers, receivers, and devices under test. Source wavelength, attenuation, output state, and supported modulation settings can be controlled as part of an automated procedure.

Communication cables, computer interfaces, drivers, software, and automation programs should be considered included only when specifically identified in the product listing.

Installation and Operation

The AQ2200-111 should be installed securely in an available slot of a compatible AQ2201 or AQ2202 frame controller. The frame should recognize the module and provide access to its source controls after installation.

A clean FC/APC single-mode patch cord should be connected to the optical output. The source wavelength, output state, attenuation, and external modulation settings can then be configured through the frame controller.

The optical output should begin at a reduced level when a new device under test is connected. Power can then be increased gradually while the receiving equipment and device limits are monitored.

The module should complete the required warm-up period before wavelength accuracy, power stability, or other precision measurements are recorded.

Laser and Connector Safety

The AQ2200-111 emits infrared optical radiation near 1310 nm. This light is not visible to the human eye, and the absence of visible light does not indicate that the output is disabled.

Users should not look into the optical port, patch cord, adapter, or exposed fiber end. The output should be disabled before connectors are inspected, cleaned, attached, or removed.

Only compatible FC/APC interfaces should be connected to the module. FC/PC connectors must not be directly intermated with the angled optical output.

Comprehensive Functional and Performance Testing

The Yokogawa AQ2200-111 receives comprehensive functional and performance testing before shipment. Evaluation may include installation in a compatible AQ2200 frame, module recognition, startup, output enable and disable operation, wavelength setting, optical attenuation control, and external modulation response.

Optical testing may include verification of output near 1310 nm, optical power near the configured 10 mW maximum, wavelength accuracy, side-mode suppression, attenuation range, attenuation step operation, and short-term output stability when appropriate calibrated equipment is available.

The FC/APC output, modulation input, front-panel controls, module connector, enclosure, labels, alignment hardware, and installed option markings may be inspected for contamination, damage, corrosion, or excessive wear.

The exact testing scope depends on the available AQ2200 frame, wavelength meter, optical spectrum analyzer, optical power meter, FC/APC reference cable, modulation source, and requested operating points.
