Noyes OFL280 Handheld FTTx Single-mode OTDR

NEW: This model was replaced by OFL280 FlexTester

The Noyes OFL 280 from AFL Telecommunications is a single-mode OTDR (Optical Time Domain Reflectometer) offered in two FTTx-optimized models. The 'installation and repair' model can operate at three wavelengths (1310/1550/1625 nm) on dark fibers but automatically switches to a filtered, 1625 nm only mode if a live fiber is detected. In addition, the test port is equipped with a PON power meter, which allows the OFL280 to detect live FTTx fibers, measure FTTx network power levels, and fault-locate live FTTx fibers with a single OTDR to network connection and a single automated test. A conventional three-wavelength (1310/1490/1550 nm) 'construction' model is also available to certify or fault-locate dark fibers in FTTx or other networks.

Both OFL280 models can operate in Full Auto, Real-Time, or Expert (manual) modes, and offer precision event analysis, an optical power meter, laser source, 12-hour battery life, internal data storage, and USB connectivity. OTDR and OPM test ports are equipped with tool-free adapters, which can be changed in seconds.

Results are saved as industry standard .SOR files, which can be transferred to a PC for viewing, printing, and analyzing with supplied Windows® compatible software.

Applications:
• Test dark fibers at up to three wavelengths
• Test live FTTx fibers at 1625 nm
• Measure splice, connection, and end-to-end loss
• Measure connection reflectance
• Measure FTTx downstream power levels at 1490 and 1550 nm
• Troubleshoot splice trays, terminals, and patch panels using the VFL
• Locate fiber 'macro' bends
• Trace fibers up to 5 km using the VFL
• Measure end-to-end loss using the OLS and OPM.
