The Optical Multimeter combines the functions of a Laser Source and a Power Meter
into a single simple to use instrument used to test fibre optic cables and equipment.
Laser Source and Power Meter in one single test set
By transmitting light at a known power level at one end of a fibre with the built-in laser source, or an independent Optical Light Source, and measuring the power at the other end with the built-in power meter, the Attenuation (loss) of the cable can be calculated. The power meter can also be used to measure the output power from optical equipment. The power meter is calibrated at a large number of wavelengths to enable power measurements to be made on a wide range of Single Mode and Multimode fibre optic cable systems. The light output from the source can be modulated and the modulation frequency can be detected by the meter, enabling errors of fibre identification to be eliminated. Output power quoted is typical, and depends on the arrangement of the connectors and patch cords used. For accurate loss measurement the instrument can be used in relative mode, eliminating errors due to the output power uncertainty and the patch cords. Settings are made using simple menus with navigation push buttons on the front panel of the tester.
Trend’s Optical Multimeter is a tester capable of characterizing the loss of optical fibre links and rings. The outstanding features of this tool include a large memory to store results, and external PC software for results analysis. The tester is supplied as standard with two sets of adaptors enabling it to be connected directly to FC, SC or ST terminated cables. An optional adaptor for LC cables is available. Power supply is from internally rechargeable batteries or from the mains. |
