Mini Mechanical Variable Optical

Attenuator Through Type (MVOA-T)

MVOA-T Series

Oplink’s Mini Manual Variable Optical Attenuator (MVOA-T) uses a neutral den-

sity filter to attenuate light. It features high resolution, a wide dynamic range, and

convenient manual adjustment. It has low insertion loss, low wavelength depen-

dent loss, and low polarization dependent loss. It is designed for pre-emphasis

attenuation, detector saturation control, in-line power equalization and amplifier

power control.

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.
