Embodiment Construction
[0016] A method for protecting the port of an optical terminal from being damaged by lightning and surge pulses. It is to connect an optical cable protector between the port of the optical terminal and the reinforcing rib of the optical cable, and the optical cable protector is provided with a surge double-circuit on-off control part to control The path and disconnection of the surge circuit in the working state of the optical cable protector.
[0017] When there is no surge, the two side electrodes and one center electrode of the optical cable protector are in an open circuit state, and they do not interfere with each other.
[0018] When there is a surge, the corresponding side electrode and the center electrode from which the surge comes from present a short circuit state. At this time, the surge pulse is led to the ground through the center electrode. After the surge pulse passes, the two electrodes quickly return to an open state. , waiting for the surge pulse to come aga...

The invention provides a method and a device for protecting an optical transceiver from destruction of thunder and surge pulse. In the method, an optical cable protector is connected between the port of the optical transceiver and an optical cable reinforcing rib, and is provided with a surge two-circuit on-off control part to control connection and disconnection of a surge circuit in working state of the optical cable protector. The optical cable protector comprises a cylindrical shell, and edge electrodes and a center electrode, wherein the edge electrodes and the center electrode are arranged on the shell; an end cover is arranged at the opening end of the shell; the end cover and the shell are in threaded connection; one edge electrode is arranged in the center of the end cover; in the inner cavity of the shell, the distance between the semispherical cambered surface of each edge electrode and the spherical cambered surface of the center electrode is between 0.2 and 1.5mm; and two flat washers, a spring washer and a nut are arranged on each edge electrode and the center electrode.
Description
technical field [0001] The invention relates to the technical field of lightning protection equipment, in particular to a method and a device for protecting the port of an optical transceiver from being damaged by lightning and surge pulses. Background technique [0002] With the rapid development of economy and technology, the number of optical transceivers used in communication data transmission has also increased sharply. However, in the thunderstorm season every year, many optical transceiver interfaces are damaged. After the optical transceiver interface is damaged, the communication room ( Station) data transmission fails, leading to communication paralysis, the loss caused by such a situation is self-evident, especially in high mountains and remote areas, the communication room (station) cannot be eliminated in time after the failure occurs, this is in While bringing economic losses, it also led to public resentment. From the current understanding, the main reason fo...
