The AQ2200-642 reduces the complexity and cost of 10G optical transceiver testing by combining bus and power control features into the same mainframe that performs Signal Generation, BERT and Optical testing.


One of the challenges for engineers involved with the development or maintenance of complex electromechanical systems is to link the behavior in one part of a system to control signals in another. In particular, engineers often need to understand causality: the relationship between an event (the cause) and a second event (the effect) to obtain an insight into an electromechanical system’s overall behaviour and to plan corrective actions accordingly.


After a disastrous 2009, the large publicly held test companies enjoyed booming business in 2010.


No, although the basic shape is the same for both the AQ9335 and AQ9335C, the internal physical deisgn for the AQ9335C has been changed slightly to fit the AQ2200 series sensor modules for optimum accuracy. You will ...


One possible way to create a non-blocking 4x4 switch on the AQ2200 Multi Application Test System is by using multiple 2x2 switch modules. Please refer to the attached file. ​


The analog output of the AQ2200-211 Sensor Module converts digital data to analog data in 100 us interval. It is not a direct output of an analog amplified but it is a D/A output. ​


The following are the specifications for the AQ2200-111 1490nm DFB Module:- Center wavelength: 1490nm+/-10nm- Wavelength accuracy: 0.05nm- SMSR: 30dB or morePlease refer to the datasheet for the AQ2200-111(1310) ...


Please download and refer to the attached document for complete instructions on how to upgrade the firmware for the AQ2201/AQ2202 Frame Controller.


The meaning of "Monitor port: -13 dB" is that -13 dB corresponds to about 5% (10Log(0.05) nearly equals to -13). That is, output power is divided by an optical coupler at a ratio of 95:5, and 5% is for monitor ...


Yes, the AQ2200-141/-142 FP-LD modules have a built-in isolator. The isolation is 35dB.


The Chopped Light mode is used: To increase measurement level sensitivity by cutting the high frequency noise To detect only the light that the LS emitted, effective for free space measurement. In free space ...


If you have products currently in China that require calibration or repair, you may either return them to your local Yokogawa service center or the Yokogawa China Service & Repair Center.   Please be advised that ...


No, unfortunately due to the number of current fiber combinations, we do not stock optical fibers. There are many companies that specialize in optical fiber cords.
