Datasheet

Overview

The VIAVI Multiple Application Platform (MAP Series) Tunable Distributed Bragg Reflector (DBR) Laser (mTLG-C3) is a tunable laser module for DWDM testing that requires changing the wavelength on demand over the C- and L-band with 50 GHz channel spacing.

The mTLG-C3 is based on a Sampled Grating Distributed Bragg Reflector (SG-DBR) laser with an integral wavelength locker. The module integrates up to four VIAVI TOSA-based Integrable Tunable Laser Assemblies (ITLA), each combining the laser, a Semiconductor Optical Amplifier (SOA) and the wavelength locker in a hermetically sealed package. The integrated wavelocker and automatic power control loop provide stable operation.

Configurations

The module is offered with C- or L-band tunability and with 1, 2 or 4 sources per module. The C-band version is available in standard power (15 dBm) and high power (16.5 dBm) versions, and a combined single C-band and L-band configuration is also available.

Platform and control

The mTLG belongs to the LightDirect module family of the MAP Series, a modular rack-mountable or benchtop optical test platform that is LXI compliant and supports SCPI-based automation drivers. Wavelength and output power are set through the MAP local interface or automation interfaces, and the graphical user interface offers summary and detailed views. The module is compatible with current MAP-300 and MAP-220 chassis.
