Optical Power Meter Block Diagram

A modular optical power meter is provided which comprises a plurality of modules each of which contains a matched compatible set of elements consisting of a terminal connector a source of optical power and a sensor for sensing optical power.

Optical to arduino direct interfacing is possible via optical sfp modules. But a light source and power meter measurement does not indicate if. Optical power meters page 1 optical power measurement solution note 153 1 the basis of fiber optic. The ability of simple arduino to optical interfacing will be advantages in some cable network and noisy environment like factory automation.

Diy optical power meter block diagram. Figure 4 otdr block diagram laser light source. Figure 1 shows a simple block diagram of the front end of an optical receiver. A simple circuit is illustrated in fig.

The dominant noise sources in this section are the linear components that provide the optical to electrical conversion namely. The output power meters is designed to directly measure the output power in an arbitrary load. Otdr block diagram the otdr consists of a laser light source an optical sensor a coupler splitter a display section and a controller section. With the exception of power meter calibration thermal power meters are rarely used in fiber optics.

In addition to power the output meter can be used to measure impedance and frequency response characteristics. The instrument provides a set of resistive loads to be selected for power measurements. Average optical power can be measured easily and reliably with a relatively inexpensive optical power meter. Speed limitation may depend on arduino processing and peripheral throughput.

These elements are configured for compatibility with each other and with the type of fiber optic system for which the particular elements comprising.
