Fast Optical Power Meter Probe Computer Controlled 850 ~ 1700nm

summarize:

The sampling period of the U8721 high-speed optical power meter module of Guangzhou Youxi can reach the uS level, and the data can be acquired and processed more quickly. The power meter module adopts USB communication interface, which can communicate with PC directly, display data and set parameters through configuration software.

The U8721 high speed optical power meter module can be used in high precision WDM components, optical waveguide grating array AWG components, planar optical waveguide PLC components, WSS, OPM, DPSK, optical amplifier EDFA and other general optical fiber optical measurement applications. Compared with other models of Guangzhou Youxi power meter, U8721 has the characteristics of high-speed sampling, and small shape, especially suitable for assembly into multi-channel optical power meter sampling system.

Other users will ask the following questions:

1.What fiber link is needed for light source and power meter execution?

A light source and a power meter are required to perform the most important measurement of a fibre optic link, the total insertion loss of that link. Basically, you compare the amount of light going into one end of the fibre with the amount of light coming out of the other end of the fibre.

.

2.What is good dBm for fiber?

Positive dBm means power greater than 1mw and negative means less than 1mw. A good laser source for a singlemode link will have a power output of ~ +3 to +6 dBm - 2-4mw - coupled into the fiber. A VCSEL for multimode links should have a power around 0dBm - 1mw.
