Improved Short Fiber Analysis
An event dead zone of less than 1m (80 cm typical) and a
sampling resolution of 5 centimeters allow the MT9083A to
evaluate connections and troubleshoot central office, FTTx
and intra-building faults with ease – providing a level of
detail never before seen.

detail allowing users to quickly determine where the problem is-even
when events are closely spaced.
Active fiber check
Not only can OTDR measurements be effected when the
optical fiber is in-service but there is a potential risk of
damage to the transmitter and OTDR receiver. To prevent
these problems, the MT9083A verifies if light is present
before starting measurement and will not transmit if it is. An
on-screen warning and internal OTDR protection are also
part of this useful feature.
Waveform Comparison Function
Compare current and stored trace data to easily assess
changes over time and to locate problems before they effect
service or compare traces at different wavelengths to iden-
tify installation issues such as macrobending.
Integrated Macrobend Detection
With many technicians making the switch from copper
installations to optical fiber, installation issues such as mac-
robends are bound to occur. To help prevent this, Anritsu
has developed a macrobend detection feature for the
MT9083A that will alert technicians when a possible mac-
robend is present. This provides a higher quality of service
for the customer and eliminates costly troubleshooting for
you.
Supports Two Display Types
There are two types of 6.5-inch, TFT, color LCD—the
Standard type (MT9083A), offering easy viewing for working
Extended Range Testing of 100+ km Fibers
In addition to its superb high-resolution performance, the
MT9083A also features up to 38.5dB of dynamic range
allowing it to easily test 100+ km spans making it a very
useful tool for any network type.
indoors, and the Enhanced type (MT9083A1), offering easy
viewing for working both indoors and outdoors
Event Table with User Defined Thresholds
PASS/FAIL thresholds for key acceptance criteria such as
splice loss, connector loss and reflectance can be set in
the MT9083A allowing technicians to easily assess a fiber’s
condition. Failing values are clearly highlighted in the event
table alerting technicians of potential problems.
Multiple Wavelengths and Models
With nine available wavelengths spanning both single mode
and multimode, the ACCESS Master MT9083A is sure to
meet your individual needs. Up to four of these wave-
lengths can be combined into a single optical output provid-
ing full spectrum characterization.
Wavelengths for Today’s Networks
Sometimes you just need more than the traditional 1310
and 1550 nm wavelengths to certify your next genera-
tion networks. The MT9083A offers a host of specialized
wavelengths including1383 nm for water peak verification
of CWDM carrying fibers, 1650 nm (with integrated filter) for
live fiber troubleshooting, 1490 nm for verification of voice,
data and IP based video services and 780 nm for in-service
troubleshooting of FTTx networks - without the need for any
additional filters.
Evaluation of access networks ranging from a few kilometers to metro networks reaching up to 100 km in length is
becoming commonplace, requiring OTDRs to have the performance and functions for evaluating both short and long fib-
ers. Designed with this in mind, the ACCESS Master delivers on both fronts.
