Designed to work with the AQ2200 series frame controllers, the new modules offer improved performance over the existing AQ2200-221.AQ2200-212 is a single channel sensor, complete with an analogue output portAQ2200-222 is a dual channel sensorBoth offer a power range of +15 to -90dBm (compared to +10 to -70 dBm for the AQ2200-221).


“The modules can also achieve a seamless measurement of approximately 30dB without switching the measurement range,” said the company.


Uncertainty for both is ±2.5%, compared with ±3% for the earlier module. Also, minimum averaging time has been halved to 100µs compared to the AQ2200-221.Other performance figures include: 800 to 1700nm wavelength range and a polarisation dependence of 0.02dB.Use is foreseen amongst manufacturers needing to test lasers, optical transceivers and optical amplifiers, as well as passive component manufacturers producing items such as optical fibres, optical connectors and optical couplers. They can also be used by makers of optical transmission systems.


“One of the main applications of the products is I/L curve [drive current/optical power] measurement of laser diode modules,” said Yokogawa. “Another is stress testing of an optical fibre cable. Multiple AQ2200-212s allow optical inputs from the fibres to be measured following the application of a shock load, with the corresponding data sent to a data recorder via the analogue outputs.
