Overview
The VIAVI MSRC-C26000DF-M100-MFA is a single-output Distributed Feedback (DFB) laser module in the Multiple Application Platform (MAP) General Purpose Light Source (mSRC-C2) family. It provides a stabilized, fixed 1625 nm wavelength on single-mode fiber with an FC/APC connector. VIAVI positions this wavelength as an OTDR sensing channel.
DFB lasers are narrow-linewidth lasers. A grating defines the output wavelength precisely. They offer good side-band suppression, are inherently mode-hop free, and are typically used where wavelength and power stability matter most. The module is TEC stabilized and has internal optical isolators that remove stability effects caused by back reflection from dirty or open connectors.
Platform
The mSRC belongs to the LightDirect module family of the VIAVI MAP, a modular rack-mount or benchtop optical test platform. MAP chassis hold 2, 3 or 8 application modules. The platform is LXI compliant and comes with SCPI-based automation drivers and PC-based management tools. A graphical user interface switches between summary and detailed views. The mSRC-C2 is compatible with all current MAP-300 and MAP-200 chassis.
