AT4X2X
Multi-mode Attenuator
AT4X2X series Multi-mode Attenuators are new class of remote-controlled fiber optic instruments for optical transceiver and network integration test. High setting speed of attenuation and power as well as power measurement capability, combined with USB, and LAN interfaces provides increased throughput and operational efficiency to meet today’s challenges both in R&D and manufacturing.
AT4X2X series attenuators feature both attenuation mode and power control mode. With integrated input and output monitor power-meter, it is the unique tool to combine both attenuator and power-meter in one box.
In attenuation mode, the calibrated value of attenuation in dB can be set. The power control functionality allows you to set the power level at the attenuator output. The instrument uses the feedback signal from a photodiode after a monitor tap, both integrated in the instrument, to set the desired power level at the output of the module.
