Class M Laser Product (IEC )
The mTLS-C1 is continuously
tunable high-power laser source
for general purpose applications
across DWDM, optical amplifier
and silicon photonic test
applications. As part of the MAP
family, the tunable laser is ideal
for use in R&D, NPI and volume
manufacturing and is easily
integrated into a diverse set of
applications alongside the over
15 modules currently offered in
the MAP.
Functional Description
The 3-slot module can be housed in the MAP-330 or MAP-380
chassis. In a standalone application, the MAP-330 is ideal and
delivers premium performance in one of the smallest footprints on
the market. In a MAP-380 there are 5 additional application slots for
use with optical switches, power meters, optical spectrum analyzers
and a full host of signal conditioning modules.
The laser can be tuned with picometer resolution across the full
wavelength range from 1520 nm to 1635 nm. Unlike models that
used current tuning to set the output power, precision power control
is achieved using an embedded VOA to ensure maximum stability
(figure 1) and guarantees low ASE (figure 2) performance across all
power and wavelength ranges. 10 dBm output power with PM fiber
coupling makes it ideal for waveguide characterization without the
need for additional polarization controllers.

2 Continuously Tunable Laser Source (TLS-C1)
Housed in an LXI compliant MAP Series chassis, test automation
can be accomplished quickly and efficiently. It is a complimentary
module to the high density mTLG-C1 grid tunable laser and
is differentiated by its ability to tune continuously across the
wavelength range.
An intuitive graphic user interface (GUI) is optimized for use in either
a laboratory or a manufacturing environment. Efficient transition
between summary widgets
(figure 3) allow users to
operate at a system level
or access the full power of
a module (figure 4).
A full SCPI command line
interface is available along
with IVI compliant drivers
if required.

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 mTLS 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 mTLS is compatible with all current MAP-300 chassis.
