When high-speed optical power changes, how to quickly capture the light power value accurately, the performance of the optical power meter is put forward very stringent requirements, the traditional optical power meter to measure the accuracy of the numerical and the demand of large dynamic range, on the power value of integral and switch range takes up a lot of time, so can't quickly and accurately the output optical power value effectively. Therefore, it cannot meet the application requirements of high-speed automatic test system and high-speed monitoring system, so high-speed optical power meter arises at the historical moment.
High speed optical power measurement scheme
High-speed optical power meter module, on the principle of design and component selection which is to ensure that the high speed power output and satisfy high speed under the large dynamic range (+ 10 DBM ~ - 70 DBM) requirements, highest can provide 10 KHZ high-speed continuous acquisition (full range), equipped with 10 million measuring depth of the storage of data (per channel), support for user input and analog output can be configured to trigger, cooperate with tunable light source, for passive components (such as DWDM, AWG, WSS) quick scan test provides a kind of high efficiency, high performance testing solutions.
Continuous power refreshes frequency up to 10 KHz (full range)
High-speed optical power meter can realize the rapid acquisition and measurement of instantaneous fluctuation of optical signal and noise, restore the fluctuation details of signal, and characterize the continuous change of optical signal.
Automatic gear shift acquisition and measurement in high speed mode
It is very important for accurate acquisition and measurement of power changes in large dynamic range to provide fast automatic gear shifting acquisition in high speed mode.
Easy to integrate automatic control instructions + exclusive DEMO software
Omega, a universal optical test platform, is equipped with Ethernet interface, RS232 interface and USB communication interface. Users can easily achieve secondary software development by equipped with universal communication protocol instruction set. At the same time, it also has its own DEMO software to facilitate customer evaluation and display.
Typical applications
In the fast scan test of passive devices (DWDM, AWG, WSS, etc.), spectrum isolation is a key link to measure the multiplexing wavelength of the device. It will determine the cross-talk of the signal in different wavelengths, evaluate the insertion loss of the specified wavelength and the suppression of other wavelengths to isolate or route the wavelength to other locations.
