Description

The AQ6150B Series Optical Wavelength Meter is an ideal instrument for accurately measuring the optical wavelength of optical devices and systems with wavelength ranges from 900 nm to 1700 nm. By employing a Michelson interferometer and a high speed Fast Fourier Transform (FFT) algorithm, the AQ6150 series can measure not only a single wavelength laser signal, but also a multiple wavelength laser signal from a DWDM system and Fabry-Perot laser. Furthermore, this technology enables the measurement of modulated laser signals in addition to the CW signal from an optical transceiver. The optimized optical design and data processing routine significantly reduces the measurement time and improves manufacturing throughput.
High wavelength accuracy of ±0.2 ppm There are two models in this series. The High Accuracy AQ6151B model offers an accuracy of ±0.2 ppm to meet the most demanding precision requirements. The Standard Accuracy AQ6150B offers a ±0.7 ppm accuracy for applications with less demanding requirements, at a more affordable price. The real time correction feature utilizes a highly stable reference signal from the built-in wavelength reference light source in order to provide long-term stability for each and every measurement taken. CW, modulated transceiver and optical filter measurement The optical output of optical transceivers and optical transmission systems is modulated with a transmission frequency including 10 G and 25 Gbps. The built-In Optical Spectrum Analysis capability utilizing an FFT technique is required to measure the spectrum broadened by the modulated signal. In addition to the regular CW light mode, the AQ6150 Series has a modulated light mode. The modulated mode analyzes the optical spectrum and discovers the center wavelength of the modulated light. This mode can also be used for the center wavelength measurement of optical filters such as a band pass filter, AWG and WSS. Simultaneous measurement of up to 1024 wavelengths AQ6150 series can measure up to 1024 wavelengths in a single input signal with a minimum separation of 5 GHz simultaneously, quickly, and accurately. This means it can meet testing needs in the development and production of WDM transmission system today and in the future as well. The multi-wavelength measurement capability contributes to production efficiency and cost reduction in the production of single-wavelength laser devices as well, by combining multiple laser modules or optical transceivers using an optical coupler and measuring all the signals at once. Delivering high performance even with low-power input signals Equipped with an Auto Gain Control (AGC) function, the AQ6150 Series adjusts the gain of the electrical amplifier automatically based on the input signal power. This helps maximize wavelength accuracy and measurement speed even if the input signal power is as low as &minus,40 dBm. Improve Productivity Increase throughput with high speed measurement For the adjustment and characterization of tunable laser sources and tunable optical transceivers requiring hundreds of wavelength measurements per device, high-speed measurement and processing capability are crucial for improving the production throughput. Both models can acquire, analyze and transfer a measurement to a PC in less than 0.2 seconds! This is 2 times faster than our AQ6150 or AQ6151 model, thus vastly improving production throughput. In the Repeat measurement mode, the AQ6150 series can collect 10 measurements per second, making it extremely useful when adjusting a device while monitoring the wavelength in real time.''
