Mini Mechanical Variable Optical
Attenuator Through Type (MVOA-T)
MVOA-T Series
Product Description
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.
