In the fiber-optic system, much like the electronics multimeter. Optical fiber measurement, Optical Power Meter is a heavy-duty commonly used table. Through the measurement of the absolute power of the transmitting end optical network, a power meter to be able to evaluate the performance of the light end equipment. Connection loss with a power meter and a stable light source used in combination, the ability to measure, test continuity and help evaluate the transmission quality of fiber link.
Units of the optical power is dbm, the specification of the fiber optic transceiver or switch the light emitting and receiving optical power, typically light emitting less than 0dbm minimum optical power that can be received by the receiving end is called sensitivity, is able to receive the maximum optical power less to the sensitivity value of the unit is db, called dynamic range, the light-emitting power subtracting the receiving sensitivity is permissible fiber attenuation values of the test the actual light emitting power by subtracting the actual received optical power value of fiber attenuation (db), the receiver receives the optimum value of the optical power is the maximum optical power that can be received, but generally not so good due to each of the optical transceiver and the optical module the dynamic range is not the same, so the fiber concrete to allow attenuation of the number depends on the actual situation. Generally allowed attenuation is about 15-30dB.
Optical power meter is a essential fiber test instrument used for absolute optical fiber power measurement as well as fiber optic loss related measurement. It is a tool for telecom and CATV network. This hand held type fiber optic power meter features ingenious appearance, wide range of power measurement, high accurate test precision and user automatic self calibration function. FiberStore offers a full range of optical power meters to support FTTx deployments, fiber network testing, certification reporting capabilities and basic power measurements. And power meter bd502 is a example of optical power meter.
BD502A Handheld Optical Power Meter is a self-developed test instrument, with the current international advanced signal processing, microprocessor hardware and software and micro-electronics technology to provide users with high-performance, high reliability, compact, easy to operate the equipment. It was widely used in optical fiber communications, CATV, optical fiber sensing, optical information processing field, It is an important fiber optical testing instrument in scientific research and engineering. And for the BD502A optical power meter, it is specially used in maintenance of Telecom, and we can provide this high quality and trustworthy product at a very large quantity.
The Chinese fiber optic products supplier FiberStore also supplies the very sophisticated instrument, optical time domain reflectometer (OTDR). OTDR is through the analysis of the measuring curve, understanding of the uniformity of the optical fiber, defects, break, and connector coupling certain performance instruments. It is produced according to the rear of the light scattering and Fresnel reverse principle, the use of the backscattered light generated when the light is propagated in the fiber to obtain the attenuation of the information can be used for measuring the optical attenuation, splice loss, fiber fault point location and the understanding loss distribution of the fiber along the length of the optical cable construction, maintenance and monitoring essential tools. OTDR 1310- 1550NM means optical time domain reflectometer with the 1310-1550nm wavelength.
