OFL280 FlexTester
Multifunction OTDR and Loss Test Set
The Noyes OFL280 FlexTester offers an unmatched combination
of fiber optic test functions, ease-of-use, portability, and value.
All OFL280 FlexTester models include an integrated single-mode
1310/1550 nm OTDR with PON-optimized and standard test
modes, optical power meter, 1310/1550 nm laser source, and
visual fault locator.
For many users the two-wavelength OFL280-100 will provide
the best balance of functionality and value. Testing at 1310 and
1550 nm is normally sufficient to certify point-to-point or FTTx
PON fibers and allows the detection of macro bends. The threewavelength OFL280-101 and OFL280-102 models add 1625 nm
or 1490 nm respectively. Testing at 1625 nm allows testing of the
L band. Testing at 1490 nm is required by some network operators
to certify FTTx PONs. The filtered, three-wavelength OFL280-103
can certify dark fibers at 1310/1550 nm, fault-locate live FTTx
fibers at 1625 nm, and measure FTTx power levels at 1490 and
1550 nm, all from a single test port.
The OFL280 FlexTester user interface provides operating modes
suitable for a wide range of users and features a top-down menu
structure that is both easy to learn and a pleasure to use.
OTDR test results may be saved as industry standard SOR files,
which can be transferred to a PC for viewing, printing, and analysis
using supplied Windows® compatible software.
Features
•• Rugged, handheld and light weight
•• Standard OTDR, PON OTDR, live fiber OTDR, and FTTx PON meter
all from the same test port
•• 0.8 m event dead zone, 3.5 m attenuation dead zone
•• 34 dB dynamic range
•• Fast Real Time OTDR mode
•• Internal storage (>1000 OTDR traces in standard .SOR format)
•• High-contrast display is clear and bright in any lighting condition,
including direct sunlight
•• Transfer test results to a PC via USB
•• 10-hour operation, fast charge, Li-Ion battery
•• Short power-on time (< 5 sec)
•• Easy to use and learn
Applications
•• PON OTDR - FTTx PON construction certification
•• Live Fiber OTDR - FTTx service turn-up and troubleshooting
•• Full Auto OTDR - Normal (point-to point) fiber cable
construction testing and fault location
•• Expert OTDR - Full function OTDR for experienced users
•• Real Time OTDR - Fault location, splice verification, first
connector checker
•• End Locator - Quickly locate breaks or measure fiber length
•• Optical Power Meter - Measure optical power or fiber loss
•• Laser Source - Measure end-to-end loss or trace fibers using
the tone feature and a Noyes OFI
•• Visual Fault Locator - Red laser for fiber bend/break location
and tracing
