Dual-channel Desktop MEMS Adjustable Optical Attenuator
The dual-channel 0-60dB adjustable optical attenuator is a passive
optical device integrating dual independent optical path control,
which achieves dynamic attenuation of optical power through precise
mechanical or electro-optic effects. Its core functions include:
Dual-channel independent regulation
Supports synchronous or asynchronous attenuation of two optical
signals, with an attenuation range of 0-60dB, suitable for power
balancing in multi-wavelength systems (such as DWDM).
High precision and low loss
Wide wavelength coverage
