EVOA Market to Reach $7.2 Billion in 2010

SAN MATEO, Calif. August 1 -- According to a new study, conducted by ElectroniCast Corporation, the global consumption value of electronically controlled variable optical attenuators (EVOAs) will grow from $219.7 Million in 2000 to $7.2 Billion in 2010.

"Solid state attenuators are electrically tunable (electronically controlled) with various methods including magneto-optic, acousto-optic and electro-optic," ElectroniCast President Stephen Montgomery said. "The amount of attenuation is dynamically variable as applied voltage is changed over its operating range. Advantages include the fastest tuning speed and uninterrupted, inline adjustment. A high technology design, the electrically variable attenuator disadvantage includes cost and a design that resets to zero attenuation in the event of a power loss to the tuning circuit."
