Embodiment
[0027] Such as figure 1 , figure 2 As shown, a matrix optical switch of the present invention includes n input lines 1, n output lines 2 and n 2n is a natural number greater than 1; each input line is connected in parallel with n optical switch units, and each optical switch unit is connected to an independent drive unit; the first optical switch unit connected in parallel to each input line are connected to the first output line, the second optical switch unit connected in parallel to each input line is connected to the second output line, and the nth optical switch unit connected in parallel to each input line is connected to the nth line output lines; the input lines are arranged horizontally. During implementation, the optical switch unit is a reflective optical switch. Generally, the state of the optical switch unit hardly changes, so how to ensure the state of the driving current is very important. A hold function can be added to the drive circuit instead of relying ...

The invention discloses a matrix optical switch and a design method of an intelligent fiber skipping system. By constructing a matrix-type off switch, each optical switch unit has a separate driving circuit for driving and turning on, so the matrix-type control signals of the driving unit are conveniently given to control different optical switch units. After the control signal is encoded, it is connected to MCU and the Ethernet module is added to the integrated data network and the communication Ethernet respectively, so that the controllability of the intelligent optical matrix in the central computer room can be ensured maximally. A fiber hopping server with two network cards is arranged in the central computer room, which is connected to the integrated data network and the communication Ethernet respectively. In this way, any intranet computer can log in to the fiber hopping server to control all the controlled optical matrices in the jurisdiction; this greatly reduces the cost offiber optic cable maintenance and shortens the service interruption time.
Description
technical field [0001] The invention relates to a woodworking tool, in particular to a matrix optical switch and an intelligent fiber jumper system. Background technique [0002] Optical cable is the core channel of power communication at present, carrying services such as information, communication, dispatching data network, protection (important), security control, etc., and communication services often provide channels 101 and 104 for dispatching automation. Communication optical cables are vulnerable to threats such as construction, shotguns, small animals, electrical corrosion, and intentional damage. Summarizing and analyzing the cable failure experience of a power supply company, it is found that the faulty cable is usually not completely interrupted, usually because some fiber cores are damaged or the attenuation is too large, but there are still a large number of fiber cores that are well connected; because there are usually a large number of idle fiber cores in pow...
