JDSU MAP 200 mTLG C1C40 Four Channel C Band Tunable Laser Source for DWDM

JDSU MAP-200 mTLG-C1C40 Four Channel C Band Tunable Laser Source for DWDM: Verified 50 GHz Tunable DFB Sources on the ITU Grid

The JDSU MAP-200 mTLG-C1C40 Four Channel C Band Tunable Laser Source for DWDM is a four-laser tunable source module for the JDSU MAP-200 platform, providing four independent 50 GHz DFB lasers tunable across the C-band. It is designed for DWDM testing where wavelength must be changed on demand across the ITU grid, and it supports applications including system load test, insertion loss measurement, test station calibration, and continuity testing.

Key Features and Benefits of the JDSU MAP-200 mTLG-C1C40 Four Channel C Band Tunable Laser Source for DWDM

• Four independent tunable DFB lasers — The C1C40 configuration provides four tunable 50 GHz DFB lasers in one module for dense multi-channel DWDM test setups.
• Full C-band tuning range — Each laser tunes from 191.0 to 196.25 THz (1527.60 to 1569.59 nm), covering the standard ITU C-band grid.
• 50 GHz channel spacing — Native ITU-grid support at 50 GHz for direct DWDM channel selection.
• Narrow linewidth =5 MHz — Suitable for coherent system testing and high-resolution component characterization.
• Output power up to 13 dBm — Setting range of 7 to 13 dBm per channel supports link-loss testing and amplifier loading without external boost.
• 40 dB minimum SMSR — Strong side-mode suppression ratio delivers clean spectral output for accurate DWDM measurements.
• ITLA-based architecture — Built around JDSU TOSA-based Integrable Tunable Laser Assemblies with integrated wavelength locker in a hermetically sealed package.
• SCPI programmable — Full SCPI command set accessible via TCP/IP, GPIB (through the MAP-200 CMR), or LXI for automated test integration.
• Hot-swappable MAP-200 module — Plug-and-play installation into any MAP-200 chassis slot without powering down.

Advanced Capabilities

Each laser channel is built on an ITLA that combines a Sampled Grating Distributed Bragg Reflector (SG-DBR), a Semiconductor Optical Amplifier (SOA), and an integral wavelength locker inside a hermetically sealed TOSA package. This integrated architecture is what delivers the module's wavelength accuracy of ±2 GHz (±0.016 nm) and long-term stability of ±0.01 nm typical over 24 hours — performance that is difficult to achieve with discrete DFB sources.

The module also supports coherence control, activated per channel via the :SOURce:COHerence SCPI command, which is useful for applications where the natural laser linewidth needs to be broadened or managed. Combined with programmable per-channel power offset (:SOURce:OFFSet:POWer), engineers can compensate for external path losses and hold precise output levels at the device under test without external attenuators.

Calibration and Quality Assurance

Every JDSU MAP-200 mTLG-C1C40 is calibrated prior to shipping to OEM specifications. The order includes a Calibration Certificate, Calibration Label, and full Calibration Data. This means the module arrives traceable, audit-ready, and ready to use straight out of the box — no need to schedule a calibration cycle before putting it into service. Standard shipped accessories from JDSU also include a Calibration Certificate and Calibration Report on USB flash drive.
