JDSU mTLG-B1C10 MAP C-Band Single Tunable DBR Laser Module

JDSU mTLG-B1C10 MAP C-Band Single Tunable DBR Laser Module

The JDSU mTLG-B1C10 is a single-channel C-band tunable Distributed Bragg Reflector laser module designed for the JDSU MAP-200 Multiple Application Platform. It provides wavelength-selectable optical output for DWDM transmission testing, optical amplifier evaluation, tunable laser-grid applications, fiber characterization, and transmitter or receiver testing.

The mTLG-B1C10 covers frequencies from 191.0 THz to 196.25 THz, corresponding to wavelengths from 1527.60 nm to 1569.59 nm. Its 50 GHz channel spacing supports controlled wavelength selection across the C-band, while its optical power can be set from 7 dBm to 13 dBm for different component and system test requirements.

The module is based on a Sampled Grating Distributed Bragg Reflector laser with an integrated wavelength locker. Wavelength and output-power settings are controlled through the MAP-200 local interface or compatible automation interfaces. The integrated wavelength locker and automatic power-control loop support stable operation during laboratory, manufacturing, and automated test procedures.

C-Band Tunable Wavelength Operation

The JDSU mTLG-B1C10 provides a C-band wavelength tuning span of approximately 42 nm. Its frequency range extends from 191.0 THz to 196.25 THz, corresponding to wavelengths from 1527.60 nm to 1569.59 nm.

The module supports 50 GHz channel spacing, allowing users to select optical channels for DWDM component and transmission-system testing. This capability is useful when evaluating optical filters, multiplexers, demultiplexers, wavelength-selective components, optical amplifiers, transmitters, receivers, and other wavelength-dependent devices.

Wavelength accuracy is specified at ±2 GHz, equivalent to approximately ±0.016 nm. Typical wavelength stability is ±0.005 nm over 15 minutes and ±0.01 nm over 24 hours under the stated operating conditions.

Adjustable Optical Output Power

The mTLG-B1C10 provides an optical power-setting range from 7 dBm to 13 dBm. At the maximum setting, the C-band output power is greater than 12 dBm. This adjustable range allows the source to support optical component characterization at different launch levels.

Typical power-setting resolution is better than 0.1 dB. Typical output-power stability is ±0.005 dB over 15 minutes and ±0.03 dB over 24 hours under the specified conditions.

The combination of adjustable power and wavelength control can reduce the need for multiple fixed-wavelength sources in tests requiring several C-band channels. An external optical attenuator may be required when a test level below the module’s minimum 7 dBm setting is needed.

SG-DBR Laser Technology

The mTLG-B1C10 uses a Sampled Grating Distributed Bragg Reflector laser. This tunable laser architecture supports electronic wavelength selection across the C-band while maintaining a narrow optical spectrum.

The natural instantaneous linewidth is specified at 5 MHz or less. When measured using self-homodyne methods, the indicated linewidth is typically between 50 MHz and 100 MHz. The measurement method should therefore be considered when comparing linewidth values or integrating the module into a specific optical experiment.

The side-mode suppression ratio is specified at a minimum of 40 dB. Relative intensity noise is typically -140 dB/Hz, with a specified maximum of -135 dB/Hz.

Integrated Wavelength and Power Stabilization

An integrated wavelength locker helps maintain the selected optical channel during operation. This capability is important in DWDM measurements where small wavelength changes can affect insertion loss, channel isolation, passband response, and other device characteristics.

The automatic power-control loop helps maintain the selected output level. Together, the wavelength locker and power-control system support repeatable measurements during channel selection, long-term component evaluation, automated production sequences, and repeated device testing.

The specified wavelength and power stability values apply at full power after a one-hour warm-up and at a constant temperature within 25 °C ±3 °C.

MAP-200 Platform Integration

The JDSU mTLG-B1C10 requires a compatible MAP-200 chassis for power, local operation, wavelength control, output-power adjustment, and automation access. The module does not function as a standalone tunable laser.

The MAP-200 platform supports Ethernet connectivity and interchangeable virtual instrument drivers for integration into automated optical test environments. This allows wavelength and power settings to be controlled locally or through compatible automation software.

The modular architecture allows the laser to be combined with compatible optical power meters, variable optical attenuators, optical switches, and other photonic test instruments. Buyers should verify chassis compatibility, available module capacity, firmware support, automation interfaces, and controller condition before purchase.

Measurement Preparation and Optical Interface Care

The mTLG-B1C10 should complete its one-hour warm-up period before precision wavelength, power, and stability measurements. The required wavelength and power level should be configured before connecting a sensitive device under test.

The FC/APC connector and polarization-maintaining patch cable should be inspected and cleaned before connection. Contaminated or damaged interfaces can increase insertion loss, reduce return loss, create instability, and affect polarization alignment.

The PM patch cable should be compatible with the connector key and slow-axis alignment used by the module. Fiber routing should provide suitable bend-radius control and strain relief to preserve optical performance.

Laser Safety and Compliance

When installed in a compatible MAP chassis, the MAP Tunable DBR Laser meets the requirements of Class 1M under IEC 60825-1. The configured platform also supports the stated CE, CSA, UL, IEC 61010-1, and LXI Class C requirements.

Users should never view the optical output directly or through optical instruments. The output should remain properly capped or connected to a compatible optical path whenever the laser is enabled.

Laser safety, electrical safety, chassis installation, and servicing procedures should follow the applicable MAP-200 operating instructions and laboratory safety requirements.

Calibration and Testing Before Shipment

When calibration is technically applicable and supported, the JDSU mTLG-B1C10 is calibrated before shipment. The calibration process may include verification of wavelength accuracy, wavelength stability, optical output power, power stability, channel selection, spectral performance, wavelength-locker operation, and automatic power-control functions.

Following successful calibration, the module 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 module, the unit receives comprehensive functional and performance testing. This process may include compatible-chassis recognition, wavelength tuning across the C-band range, optical output verification, power adjustment, wavelength-locker operation, output stability, FC/APC connector inspection, and local or automated 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 mTLG-B1C10 is specifically the C-band single-laser configuration. Buyers should confirm that the 1527.60 nm to 1569.59 nm wavelength range, 50 GHz channel spacing, 7 dBm to 13 dBm power-setting range, FC/APC connector, and polarization-maintaining fiber match the intended application.

The mTLG-B1C10 should not be confused with the mTLG-B1C20 dual-density module, mTLG-B1C40 quad-density module, or corresponding L-band configurations. Each product code identifies a specific wavelength band and channel density.

Buyers should review the module condition, optical connector condition, MAP-200 chassis compatibility, calibration status, firmware support, and included accessories. A compatible MAP chassis, PM FC/APC patch cables, automation software, and measurement equipment may be required separately.
