随着光纤接入市场的日趋升温,业内公认以无源光网络技术PON(Passive Optical Network)为代表的新一代光纤接入技术将迎来快速发展时期。无源光网络PON指ODN(Optical Distribution Network:光配线网)不含有任何电子器件及电子电源,而全部由光分路器(Splitter:分支器)等无源器件组成,不需要贵重的有源电子设备。与有源光接入技术相比,PON由于消除了局端与用户端之间的有源设备,使得维护简单、可靠性
With the increasing market access of optical fiber, the industry recognizes that the new generation of optical access technology represented by Passive Optical Network (PON) will usher in a period of rapid development. Passive optical network PON refers to the optical distribution network (ODN) that does not contain any electronic devices and electronic power supplies. All optical components are composed of passive components such as optical splitters. They do not need to be expensive Source electronics. Compared with the active optical access technology, PON eliminates the need for active equipment between the central office and the customer premises for easy maintenance and reliability
