Boston Applied Technologies'
EclipseTM Multimode Variable Optical Attenuators (MM-VOAs) maintain a
constant output optical power in the multimode fiber transmission line,
regardless of the wavelength and the level of attenuation. Based on the
revolutionary OptoCeramicTM electro-optic technology, the MM-VOAs
achieve very high speeds (with a typical transition time of less than
a few microseconds) in a compact solid-state device. The MM-VOAs with
integrated input tap or output tap (photo detector) are also available
to eliminate the need of an external optical power detection component,
substantially reducing the cost and space requirements.
