Maintenance and Operation Technologies for Optical Access Fiber Network Infrastructure

The optical access fiber network is spreading rapidly as a result of the progress made on optical communication technologies and the availability of a wide range of broadband Internet content. If the optical access network is not properly maintained, the service quality will decrease. This paper describes some effective technologies that have been researched and developed to maintain a high quality of service, and to achieve efficient maintenance and operation. key words: maintenance, operation, optical access network, testing and monitor, line switching
