Design And Development Of ODN Fiber Conductor

In recent years,optical fiber communication has been favored by communication researchers and practitioners because of its long transmission distance,large capacities and other characteristics.For a long time to come,optical fiber communication will still be the mainstream technology of the communications industry.However,wiring management problems in an optical fiber distribution room makes people cannot fully enjoy the convenience,and leads to many dead fibers and low operation efficiency.In particular,wiring management problems in some older wiring room are extremely serious,and prone to accidents,so the line port paring of wiring room is urgent,and completing wiring management work at a faster speed with a lower cost is really meaningful.In this paper,based on the analysis of the shortcomings of current optical fiber management solutions,a multi-line paring scheme for optical fibers is designed,and its hardware and software solutions are given.The hardware design of the multi-port routing device is mainly divided into two parts,first one is the PC subsystem which runs the routing software,second one is the multi-port routing subsystem based on the switch.The PC subsystem runs the routing software,sets the optical fiber port(set)to be paired and realizes the pairing of optical fiber port through the routing subsystem and the counterpart PC.Finally,The PC saves it in the database and displays the list and legend;Multi-port line subsystems uses switch to realize connection to the PC and the fiber optical port,port and the PC signal to send and receive,so as to realize more port pair of parallel search on both ends of the fiber,and through the wavelength division multiplexer to transmit signals and business reuse into rows of optical fiber,the ribbon cable transmission business at the same time,the transmission line work without disruption to business.The multi port line spreader uses IEEE 802.1Q and UDP/IP/Ethernet protocol stack to communicate,and it is realized by Visual C# calling the Scapy library in Python.The essay sets the corresponding relationship between rack,frame,disk,port number and VLAN port number,and uses Visual C# and Scapy to implement the routing process,then the pairing results of local and remote optical fiber ports are displayed in a list and stored in the database.A multi-line paring device is design and implemented,which can solve the problems like wiring chaos and low utilization efficiency of optical fibers.Flexible software design makes maintenance convenient,operators can implement fiber ports pairing work without knowing its internal mechanism,multi-line ports pairing design can greatly reduce the pairting time and plug-in plug-out times of optical fibers.
