The Multiple Application Platform (MAP) Distributed Feedback

(DFB) lasers are stabilized fixed wavelength light sources with

coverage of O-, C- and L-band telemetry wavelengths at ,

, ,  and  nm.

VIAVI offers a range of DFB lasers as part of the

general purpose light source modules (mSRC)

in the MAP portfolio. DFB lasers are offered

at the standard O, C and L-band telemetry

wavelengths, plus the common out-of-band

wavelength and power stability are key.

Functional Description

DFB lasers are similar to Fabry-Perot cavity, but with grating above

active layer. The main advantage of a distributed feedback (DFB) laser

is to sharpen up the output of regular Fabry-Perot lasers.

VIAVI DFB laser modules have excellent output power stability

(±0.025dB), figure 1. Optical isolators eliminate stability effects

caused by back reflection from dirty or open connectors.

An intuitive graphic user interface (GUI) is optimized for use in

either a laboratory or a manufacturing environment. Efficient

transition between summary and detailed views allows users to

operate at a system level or access the full power of a module.

Options and Configurations

The VIAVI DFB sources are offered in multiple individual output cassette or a single output.

modules are characterized by their simple control and single function nature. Individually or together they form

the foundation of a diverse array of optical test applications. The web enabled multiuser interface is simple and

intuitive. LXI compliant with a full suite of SCPI based automation drivers and PC based management tools, the

VIAVI MAP is optimized for both the lab to manufacturing environments.

The mSRC is part of the LightDirect module family. Alongside the many other modules, such as optical

attenuators, polarization scramblers, power meters, and spectrum analyzers, the MAP series is the ideal, modular

platform for photonic system and module testing.

The mSRC-C2 is compatible with all current MAP-300 and MAP-200 chassis.
