| Electronically Variable Optical Attenuators EVOA Series Product Description Oplink's electronically variable optical attenuator (EVOA) is a high performance opto-mechanical device. EVOA operates by moving an obstructing element into the optical beam and the position of the obstructing element can be adjusted by an integrated, electronically controlled step motor, resulting in fine tuning of attenuation. Oplink's EVOA features a large dynamic attenuation range of >30dB and an excellent optical performance over C- or L-band. Its latching operation retains recent attenuation setting upon removal of drive voltage. Applications include pre-emphasis attenuation, detector saturation control, in-line power equalization and amplifier power control applications. Also, it can be used to extend the dynamic range of optical measurement instruments. Oplink's EVOA is designed to withstand the diverse environmental conditions and compliance to the Telcordia standard GR-1221. Oplink can provide customized designs to meet specialized feature applications. Also, Oplink offers modular assemblies that integrate other components to form a full function module or subsystem.
