The AQ6370B uses a newly developed high performance monochromator to achieve high wavelength resolution (0.02 nm) and wide close-in dynamic range (70 dB). With the sharper spectral characteristics of the new monochromator, OSNR measurement of 50 GHz spacing DWDM transmission systems and EDFA evaluation with multiple wavelength sources can successfully be performed. The AQ6370B can measure optical power as high as +20 dBm, which enables direct measurement of high power sources such as optical amplifiers and pump lasers for Raman amplifiers. Measurement sensitivity can be chosen from seven categories according to test applications and measurement speed requirements. The AQ6370B uses a free space input structure that can handle up to GI 62.5/125 multimode fiber. Multimode fiber is commonly used in high speed Ethernet network, such as GE-PON.
The free space input is also beneficial for measurement repeatability as insertion loss variation at the input connector is smaller than the other input type which has an optical fiber inside the monochromator. The AQ6370B can catch the peak power of a pulsed signal using PEAK HOLD or using an externally provided trigger to synchronize with the measured signal. It can be applied to the transmission loop testing of telecommunication systems, and also to the low power measurement at the early stage of laser chip development since it works in the high sensitivity modes. The AQ6370B is equipped with GP-IB, RS-232C, and Ethernet (10/100BASE) interfaces to be connected with an external PC for remote access and building an automated test system. It is compatible with a standardized programming language and supports AQ6317 commands for easy programming. Macro Program is a useful built-in function for making a simple auto test program.
