The special nature of optical transport networks demands extremely high reliability of lines and equipment. A 1+1 optical line protection (OLP) system monitors primary and backup fibers in real time, effectively avoiding simultaneous failure of both routes. Through the backup fiber link, the system automatically switches to the backup route quickly upon failure.
