DETERMINATION OF TRANSMISSION BLOCKAGE IN AN OPTICAL TELECOMMUNICATION SYSTEM
摘要
An optical communication system (2) is provided that has a network including a transmitter station (4) that conveys data through a wireless pathway (12) to a receiver station (6). An obstruction (18) of the pathway (12) is determined by measuring the attenuation of an optical beam (10) arriving at or intending to arrive at a target receiver station (6) and comparing the value with the attenuation of other optical beam(s) (14) arriving at or intending to arrive at one or more reference receiving stations (8) in the optical communication system (2). The values are interpreted to determine the nature of the blockage (18) and various parameters in the optical data transmission system (2) controlled according to the presence of a local blockage or global blockage.
