Electrical Variable Optical Attenuator EVOA Series Features * Wide Range * Low Excess Loss * High Repeatability * High Resolution Applications * EDFA Channel Equalization * Laboratory R&D ELECTRICAL VARIABLE OPTICAL ATTENUATOR Oplink's EVOA utilizes thin film filter technology and features high resolution and a wide dynamic range. It has low temperature-dependent loss, low insertion loss, low wavelength dependent loss, low polarization dependent loss and low insertion loss ripple. Its compact size allows mounting on printed circuit boards. The attenuator features latching operation and potentiometer feedback to control attenuator settings. It is excellent for power equalization in multi-channel optically amplified networks, for gain control in optical amplifiers and for power control in receivers.
