per Laser Notice No.
Multiple Application Platform (MAP) broadband light sources featuring
Light Emitting Diode laser (LED) are stabilized, low power, fixed
wavelength modules, with output wavelengths at the two most
commonly used multimode wavelengths nm and nm.
VIAVI offers a multiplexed and individual
output low power LED as part of the
general-purpose light sources (mSRC) in the
MAP portfolio. The LEDs are offered at the
common multimode wavelengths of 850nm
and 1300nm. LED sources emit incoherent
broadband light.
Functional Description
LED sources are used for testing of
broadband multimode components. They
have a slightly broader spectral width and
lower output power than SLEDs and Fabry-
Perot (FP) lasers. The incoherent nature of LED light sources
avoids interference in short fibers with reflection present.
Mode fill is key for accurate measurement of multimode
components and systems. An under or over-filled launch can
give optimistic or pessimistic loss results that don’t reflect the
actual loss of a component or system. VIAVI low power LED
sources have ±0.05 dB power stability and a fixed power level.

Light Emitting Diode (LED) Source Module
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 LED sources are offered in two variants with individual outputs or multiplexed outputs.
LED variant Available Configurations
Individual Output Individual 850/1300 nm output
Mux’d Output Multiplexed 850/1300 nm output
Chassis and Modular Family
The VIAVI Multiple Application Platform (MAP) is a modular, rack mountable or benchtop, optical test and
measurement platform with chassis’ that can host 2, 3 or 8 application modules. The LightDirect family of
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.
