The FTB-100 Mini-OTDR is a dedicated optical time domain reflectometer that
characterizes a fiber-optic span, usually optical fiber sections joined by
splices and connectors. The optical time domain reflectometer (OTDR) provides an
inside view of the fiber, and can calculate fiber length, attenuation, breaks,
total return loss, and splice, connector and total losses.
The FTB-100 Mini-OTDR supports EXFO’s extensive line of OTDR test modules,
which offers all the features required by both intensive and occasional OTDR
users.
The Mini-OTDR:
- offers impressive dynamic range with short dead zones.
- performs quick acquisitions with low noise levels to ensure accuracy.
Low-Loss Splice Location:
- acquire OTDR traces made of up to 128 000 points that provide a sampling
resolution as fine as 4 cm.
- include a light source and can also include an (OPTIONAL) visual fault
locator.
The Mini-OTDR:
- can include an (OPTIONAL) power meter for more test possibilities.
- is available with a color or monochrome touchscreen.
- is splashproof and rugged for outside plant testing.
Trace Acquisition Modes:
- (The OTDR application provides the following trace acquisition modes:)
Auto:
- Automatically calculates fiber length, sets acquisition parameters,
acquires traces, and displays event tables and acquiredtraces.
Advanced:
- Offers all the tools needed to perform integral OTDR tests and
measurements and gives you control over all test parameters.
Create Ref./Template:
- Tests fibers and compares the results to a reference trace that was
previously acquired and analyzed. This allows you to save time when testing a
large number of fibers. Reference trace documentation is also automatically
copied to new acquisitions

Short Dead Zones:
EXFO’s FTB-7200D helps you boost test productivity for inside-plant
applications. Their exceptional 1 m event dead zone enables you to easily locate
and characterize all events between the transmitter and the central office’s
fiber distribution panel. This feature also comes in handy in metro, access and
FTTH network applications, where events are usually closely spaced.
The FTB-7200D model is ideal for private/premises/enterprise network
testing. It offers the industry’s shortest dead zones, as well as
lightning-fast acquisitions. Test multimode fiber within premises, or
singlemode fiber between premises—all with a single OTDR unit—and maximize
your return on investment.
Delivering Higher Accuracy for Event Location:
The FTB-7200D locates events with pinpoint accuracy:
- Up to 128 000 sampling points for higher trace resolution
- Sampling resolution down to 4 cm, for ultra-accurate fault location
- Better linearity—down to ±0.03 dB/dB—for more accurate event
characterization
