Modular Manufacturing Test System

A modular test platform with a wide selection of modules allows optimal configuration of test solutions for optical component and network systems manufacturing.

We offer a wide lineup of modules including variable optical attenuators with or without built-in power meters, high power & multi channel power meters, high-stability laser sources and switches in a variety of channel counts.

We have developed the AQ2200-136 compact tunable laser source module with a wide wavelength range of 200 nm (1440 to 1640 nm) and a maximum output power of +7 dBm or greater, as a plug-in module for the AQ2200 multi-application test system (MATS). When combined with the AQ2200 series of optical sensors or the AQ6317B/C/AQ6319 optical spectrum analyzer, the AQ2200-136 enables users to measure the wavelength-dependent loss (WDL) of an optical device without any personal computers. In this paper, we describe the features and structure of the AQ2200-136.


With improvements in the speed and bandwidth of communication networks in recent years, 10-Gbit/s high-speed optical communications systems are becoming increasingly widespread in core networks, as well as access networks and LANs. Accordingly, devices and modules for use in 10-Gbit/s transmission are being actively developed, causing increasingly fierce price competition. Under these circumstances, the bit error rate testers (BERT) necessary to test these devices and modules are also facing a demand for lower prices. We have explored essential functionality and performance and examined product specifications, with a focus on application to the production of optical transceivers. Consequently, we have developed two compact and economical 10-Gbit/s BERTs, a plug-in module model and a portable model, featuring variable amplitudes, cross-points and voltage offsets for the data output and a built-in clock and data recovery (CDR) function.


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, is by using multiple 2x2 switch modules. Please refer to the attached file. ​
The analog output of the AQ2200-211 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.
