Optical Power Meter for measuring absolute optical power or optical fiber by a relative loss of power equipment. In the optical measurement, optical power meter is commonly used in heavy duty table. By measuring the optical transmitter unit or absolute power, a choice of OPower Meter
　　Optical Power Meter into barrier model, the accuracy, interface parameters, use should be based on different usage requirements of users select the appropriate optical power meter, the main should refer to:
　　1, determine the type and range of your display resolution and consistent.
　　2, with the direct measurement of the dB insertion loss function.
　　3, choose the best probe type and interface type
　　4, Optical Power Meter and manufacturing evaluation of calibration accuracy calibration procedures, and requirements of your range of fiber and connector match.
