Noyes OFL280-10x FlexTester Family
Multifunction OTDR and Loss Test Set
The NOYES OFL280 FlexTester family 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 three-wavelength 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 PON 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, hand-held and light weight (0.8 kg / 1.8 lb)
• 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 .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 learn and use
