Specifications

Standard Stabilized Light Source
The OTDR port also functions as a stabilized light source
providing continuous wave, 270Hz, 1kHz and 2kHz modula-
tions for easy fiber identification. This is standard equip-
ment on all models - a chargeable option on most other
OTDRs.
Standard Integrated Power Meter
In the base unit, the OTDR port also functions as an inte-
grated power meter for verification of optical power levels.
Additional power meter options are available for higher
power transmissions and loop-back testing.
Visual Laser Source for easy fault location and
fiber identification
A Visible Light Source is useful for tracking down bad con-
nections, splices and fiber management issues such as
macrobends. The optional Visible Light Source is factory
installed in the MT9083A and features up to 5 km (3 miles)
of operation.
An OTDR, Optical Power Meter, Visible Light Source, and IP tester are built into Anritsu’s compact, light-weight MT9083A
supporting tasks ranging from searching for faults in optical fibers to QoS evaluation to FTTx troubleshooting with just one
unit.
A True all-in-one Tester
Optical Power Meter Options - up to +30 dBm
In place of the standard power meter, the MT9083A offers
four optional optical power meters; one supports both SM
and MM fibers (MT9083A-003,006) while the others feature
higher measurement range for SM only applications (-004,
-005). When measurement of high optical powers, typically
more than +20 dBm (like those used by CATV companies)
is required, power meter (Option 005) using an optical
integrator sphere can be used to make long-term measure-
ments with high stability at levels above +30 dBm.
Data Table for Saved Results
Loss test set measurements for multiple wavelengths can
be saved into a results table for easy comparison and
archiving. The table can also be saved as a text file and
exported to a PC spreadsheet program for further manipula-
tion or integration into a standard company template.
Faults that cause drops in FTTx service speed are handled differently according to whether the cause is outside or inside
the building. In addition, business users are starting to think about guaranteed bandwidth services and higher-speed gigabit
services. The MT9083A has a built-in IP Network Connection Check function that can be used for both optical fibers and
optical access QoS evaluation.
Connection and Ping Tests
The first step in testing a service is to verify continuity. The
built-in IP Connection Test Function supports both PPPOE
and DHCP services.
FTTx Download Speed Evaluation
FTTx service performance is easily evaluated from the
download throughput. Previous evaluation systems were
always limited by the PC performance (CPU speed, memory
size, OS, load) and never provided accurate measurements.
Using the MT9083A Download Throughput Measurement
function frees the results from the impact of PC perform-
ance and provides accurate results. This allows the causes
of drops in FTTx service speeds to be pinpointed to the net-
work side or the user’s PC side.
Throughput Measurement and Frame Counter
The MT9083A has a two-way throughput measurement
function for efficient evaluation of guaranteed bandwidth
services. When an MT9083A is connected to each end of
the service, both the upload and download speeds can be
evaluated. And since the built-in frame counter functions
can be used to measure received frame types and to count
error frames, network usage efficiency can be measured
easily too.
Gigabit Ethernet Support
The MT9083A has an optional built-in 1000Base-T electrical
interface for evaluating Gigabit Ethernet throughput (up to
full line rate) for verifying performance on increasing com-
mon Gigabit Ethernet service
Faults Identified
When issues are present, possible causes are displayed
on-screen to help isolate the source of the problem.
