Description

A port identification and positioning system and optical connector and adapter base

technical field

The utility model relates to the technical field of optical fiber communication, in particular to a system and a device for identifying and locating ports through RFID tags. the

Background technique

With the in-depth development of optical fiber communication, a large number of optical fiber cables need to be deployed in the communication network. In the face of large-scale mass optical fiber networks, a wide variety of optical distribution equipment, and frequent and urgent opening and maintenance customer needs, the connection of optical fiber cables Status, connection relationship and intelligent management are becoming more and more important. Therefore, the important unit of connection between optical fiber cables - optical connectors are getting more and more attention. the

At present, there are SC, LC, FC, ST and other optical connectors that are common in optical fiber networks. SC optical connectors have a rectangular shell and are fixed in the form of plug-in and pull-out pins. There is a pilot key on one side of the SC plug shell, the front end of the key is semicircular, and the rear end is square. There is a "convex"-shaped snap-in window on both sides of the pilot key, and the snap-in window is composed of two arc-shaped indented guide rails of the outer shell and a boss of the inner shell. The two ports of the SC-type adapter have symmetrical guide grooves, and there are two clip-on barbs in the adapter, and there is a cylindrical pin socket cavity between the barbs. When the guiding key on the SC plug is inserted into the adapter along the guiding groove of the SC adapter, the locking barb in the adapter will hook with the boss in the locking window of the SC plug, and the SC plug and the adapter are locked; When the guide key on the SC plug pulls out the adapter along the guide groove of the SC adapter, the arc-shaped guide rails on the snap-in windows on both sides of the SC plug slowly prop up the snap-in barbs in the SC adapter, and the snap-in barbs come off The SC plug is snapped into the boss in the window, and the SC plug is separated from the adapter. LC type optical connectors operate a modular jack latch mechanism. The external reinforcement of the FC optical connector adopts a metal sleeve, and the fastening method is a screw buckle. The housing of the ST type optical connector is round, and the fastening method is a screw buckle. the

Since the universal SC, LC, FC, ST and other optical connectors are connected in the same network, the shape, color, and structure of the optical connectors, adapters, and optical cables are basically the same, and the current marking methods are mostly paper or paper. Plastic label, the label is tied to the end of the optical cable or connector by glue or a fixed rope. Due to the connection environment, frequent operation and maintenance, and aging of time, the attached label is easy to fall off, aging, human labeling error, and on-site processing is difficult to make timely remarks management, so this method cannot effectively identify links or ports. Moreover, there is no accurate connection indication between the ports during the opening and maintenance operations, and the plugs are easy to be inserted wrongly. Once the wrong insertion is made, it is very difficult to detect. A new type of anti-mis-insertion connector assembly (Chinese patent CN 10196855) has appeared on the market. However, the structure of this new type of anti-mis-insertion connector assembly is relatively complicated, and it needs to be matched with the universal SC and LC plugs. Moreover, the information storage chip on the connector needs to be connected to the pins of the electrical adapter for information communication, which cannot satisfy plug-and-play. the
