Optical power measurements

Fiber networks require high quality workmanship. During installation and maintenance of the networks, the installer should take into account not only the correct fiber splicing, but also the geometry of the laid cables and individual fibers (bending radii).

Any irregularity may increase the attenuation of the path, resulting even in the failure of the link. For the convenience of work, every installer of optical networks should be equipped with a suitable set of diagnostic tools. The basic devices are an optical power meter and a visual fault locator.

OPTOKON PM-800 is an advanced meter designed to measure optical power loss in fiber networks based on multimode and single-mode fibers. The meter is calibrated to measure optical power at six wavelengths (nm): 850, 1300, 1310, 1490, 1550, and 1625. AWD (Auto Wavelength Detection) function allows the meter to detect the length of the transmitted wave and automatically adjust measuring parameters. It is possible to set 0 dB reference level so as to make the measurements of an optical path easier.

Visual fault locators can detect fiber faults which are not visible to the naked eye. Mechanical defects
often occur at the ends of the fibers and are the result of poor handling of the cable during installation.

The visual fault locator L5933 is designed to help diagnose problems with fiber optic cabling. The device is designed to test single-mode and multimode fiber optic cables. The output power is sufficient to check even 3 km long links. The FM-FOA-FCH locator allows for detection of light leaks in optical transmission systems. The visible red light (650 nm) can be observed at breaks, bad splices or connectors, improper bends etc, providing an overview of the problem.
