OPLINK EVOA160000032H Electronically variable optical attenuator Datasheet

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.
