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
EXFO FTB-7212B-C-EI
Today’s telecom market imposes test challenges that stem from a
never-beforeseen variety of fiber-optic networks. Ultra-long-haul,
high-fiber-count 10 Gb/s and high-speed DWDM networks. CWDM and 2.5 Gb/s
metropolitan networks. Passive optical networks (PONs) and other types of access
networks. All of these create increasingly specific and demanding testing
requirements, making OTDRs more essential than ever for installing, maintaining
and troubleshooting networks.
EXFO’s OTDRs deliver the right tools for accurately detecting and
characterizing splices, connectors, splitters, breaks and other events along a
fiber link. The FTB-7000B provides a wide choice of configurations to
conveniently test all types of networks. The FTB-7000D and FTB-70000C enables
multiple-wavelength testing by combining triple-wavelength capability in a
single module. Plus, the FTB-7000D offers extremely short dead zones—perfect for
short-distance applications—and faster-than-ever acquisitions.
EXFO’s OTDR modules meet all your testing needs with numerous singlemode and
multimode configurations available at several wavelengths. Most important, they
are field-interchangeable and compatible with both of EXFO's rugged, portable
test platforms, the powerful FTB-400 Universal Test System and the compact
FTB-100B Mini-OTDR.

Short Dead Zones
EXFO's FTB-7200D and FTB-7300D OTDRs help 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.
Multimode and Singlemode Flexibility
The FTB-7200D model combines singlemode and multimode functionalities, 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.
Optimizing Passive Optical Network (PON) Testing
Designed to meet the testing requirements brought by FTTH networks in
general, and PONs in particular, the FTB-7300D enables testing at 1310, 1490 and
1550 nm. What's more, EXFO's next-generation OTDR software lets you test through
high-port-count splitters—even 1x32 splitters—with loss levels of up to18
dB.
Delivering Higher Accuracy for Event Location
The FTB-7200D and FTB-7300D OTDRs locate 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
