| Optical power meter, the stabilization of the light source is in the field of optical fiber communication most widely used both instruments. In almost all in the measurement of optical fiber communication purposes. Optical power meter is used to measure the optical power of a meter in size, the stabilization of the light source can provide stability of wavelength, narrow and stable spectral width, and under certain conditions, a stable power output. Its wide range of generally can be divided into two categories: from the overall dimensions and size can be divided into desktop and laptop. The former is usually used in laboratories, in the engine room, which can be used in indoor use. Can be used at the construction site: from function can also be divided into two categories: ordinary and intelligent. The difference is the intelligent optical power meter has a computer system, data storage, data processing, wavelength, average display and automatic diaodang and features such as zero, and the measurement accuracy is higher. We considered a wide range of portable applications, taking into account also the intelligent type high performance. A both portable and intelligent-advantages of optical power meter. This article discusses in detail the design and implementation of optical power meter. In the design of optical power meter, the application software ORCAD PSPICE Family Release 9.2 module Optimze optimization design optical detector amplifier and its main element for use of the software Release 9.2 ORCAD Family Pspice A/D module in the Worst Case for MonteCarlo or 5% of the tolerance analysis. Power circuit DC/DC XC6368A application power conversion IC for the entire optical power meter power supply for power saving management further frugal electrical energy, more suitable for portable use. This article has designed a LCD display circuit, circuit E2PROM stores. At the same time also the optical power meter software capabilities described and software flowchart.
