Abstract
Disclosed is apparatus and method for establishing and maintaining optical data transfer between a first optical communications device ( ) and a second optical communications device ( ). The devices have a feedback communications link ( ) therebetween. An optical signal ( ), having a predetermined signal profile ( ), is transmitted from a transmission source ( ) within the first optical communications device to an optical receiver ( ) within the second optical communications device. The predetermined signal profile is transmitted from the first device, via the feedback communications link, to the second device. The signal profile ( ) of the optical signal as received by the optical receiver is determined, and compared with the predetermined signal profile to quantify any misalignment or movement of the optical signal with respect to the optical receiver. The transmission of the optical signal is then adjusted by a directing member ( ) responsive to the results of the compared profiles to align and center the optical signal with respect to the optical receiver. Once properly align, the optical signal may be utilized for high speed, high bandwidth data transmission.
