Problems solved by technology
Although the use of intelligent ODN technology can greatly reduce the error rate of manual management and reduce the workload, but due to the complexity of the construction environment and the large number of optical fibers, this technology will also bring adverse effects, such as: using serial connections to manage optical fibers Ports will make it impossible to operate multiple ports at the same time, and the communication rate limit between the upper computer and the lower computer will also lead to long waiting times, reducing the work efficiency of construction and maintenance personnel and increasing costs

The invention discloses a system and a method for parallel architecture optical fiber management. The method comprises the following steps: 1, transmitting instruction information to intelligent ODN equipment connected with a serial server, and receiving and processing the information of the intelligent ODN equipment connected with the serial server; 2, converting work order information sent by intelligent ODN management terminal software into instruction information which can be received by a single-chip microcomputer in the intelligent ODN equipment; and 3, completing operation according tothe received instruction information, and sending a command to the intelligent ODN management terminal software. The one-to-eight characteristic of a serial port server and the time delay characteristic of serial port communication make the work order information transmitted at the same time; and time delay is adopted in serial port communication, so the problem that work order information receiving and sending are disordered due to a parallel structure can be solved.
Description
technical field [0001] The present invention relates to the technical field of optical communication, in particular to a parallel architecture optical fiber management system and method. Background technique [0002] With the development of technology, in order to ensure the quality and bandwidth speed of the access network, the optical fiber access network (FTTx, Fiberto the x) technology has become the best choice, and the development of the communication industry has ushered in a new round of climax. Since PON (Passive Optical Network, passive optical network) technology is the first choice for FTTx, the core of PON technology is ODN (Optical Distribution Network). Therefore, the quality of the ODN network construction will directly determine the quality and scope of the FTTx network. An urgent problem that operators need to solve now is how to reduce the ODN construction cost. [0003] PON splits an OLT (Optical Line Terminal) to dozens or hundreds of ONUs (Optical Netw...
