Passive Utility Module (mUTL-C1)
Simplified Component Test Management for MAP Series
The Multiple Application Platform (MAP series) Passive Utility Module,
mUTL-C, is designed to simplify the mechanical integration of passive
optical components into large automated test systems and removes
the “stray” optical components that are loose and often damaged
during operation or transport. It is optimized for the industry-leading
VIAVI Solutions MAP series platform
Features and Benefits
y Mechanically robust integration of fiber
optic couplers, splitters and mux/demux
components into larger integrated test
environments
y Compact design with  bulkhead
connectors enables packaging of up to
four -port couplers
y Bulkhead only versions available for
mounting user supplied components
y Single-mode or multimode component
options.
y Multimode components are modally
transparent
y Ideal for individual lane testing of WDM
signals for next generation Ethernet
formats such as //GE
Applications
y In-line tapping of signals for power and
spectrum measurements
y Power reference branches for passive
component test
y Splitting signals for parallel test
applications
y Bit error rate test (BER)
y Passive component test
y Optical amplifier test
Safety Information
y Complies with CE, CSA/UL/IEC-
, plus LXI class C requirements when
installed in a MAP chassis
The mUTL-C1 cassettes simplifies the mechanical
integration of passive optical components
for test sets. They are highly configurable,
contain passive optical devices such as splitters
and taps. They support angle or flat polished
connectors as well as single-mode and multi-
mode fibers. Each module has user definable
data fields that can be accessed by the MAP
series chassis to assist in module identification
and displayed or recalled remotely.
Options and Configurations
A wide range of standard components are
available:
y A range of single-mode and multimode optical couplers
enabling power reference paths or tapping signals for in-
line test. They are orderable with any of six types of optical
connectors.
y G and G Ethernet standards have adopted WDM
technology for single fiber interfaces. The mUTL-C provides
Mux/Demux modules complying with the IEEE standards and
are the ideal solution to isolate individual lanes for test access.
y LAN-WDM multiplexers to multiplex and de-multiplex  LAN-
WDM channels as according to GBASE LR/ FR supporting
IEEE .bs standard.

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 mUTL is part of the LightDirect module family. Alongside the many other modules, such as light sources,
polarization scramblers, power meters, and spectrum analyzers, the MAP series is the ideal, modular platform for
photonic system and module testing.
The mUTL is compatible with all current MAP-300 and MAP-200 chassis and can also be used without a
MAP platform.
y A quad wavelength filter for shaping ASE spectrum or reducing ASE in the standard  /  /  / 
nm test windows.
y A bulkhead-adapters only module is also available for mechanical mounting of user supplied components. These
cassettes are supplied with mounting hardware and twelve bulkhead adapters for ease of integration of up to
four -port devices
