A True all-in-one Tester

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.

Complete Loss Test Set Features

Standard Stabilized Light Source

The OTDR port also functions as a stabilized light source

providing continuous wave, 270Hz, 1kHz and 2kHz

modulations for easy fiber identification. This is standard

equipment 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

integrated 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

connections, 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.

Optical Power Meter Options - up to +30 dBm

In place of the standard power meter, the MT9083A offers

three optional optical power meters; one supports both SM

and MM fibers (MT9083A-003) 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

measurements 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 manipulation or

integration into a standard company template.

Optical Access Network QoS Evaluation Using IP Test

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

performance and provides accurate results. This allows the causes of

drops in FTTx service speeds to be pinpointed to the network 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 common Gigabit Ethernet services.

Faults Identified

When issues are present, possible causes are displayed on-screen to

help isolate the source of the problem.
