Background
Fiber optic connectors are devices used for the removable connection of optical fibers to one another. In some usage scenarios, multiple fiber optic connectors need to be connected to the same panel to transmit a large amount of data.
As technology continues to evolve, it is often desirable to deploy higher density panels, i.e., to connect more fiber optic connectors on smaller area panels. In the related art, the density of the arrangement of optical fibers on a panel can be increased by reducing the size of the optical fiber connectors or reducing the spacing between adjacent connectors on the panel.
The capacity and the speed of an optical transport switching network are developed at a high speed, and the number of switching nodes such as a core switching network, a data center and the like is more and more. The popularity and application of high-speed transmission modules has made the need for high-density, miniaturized fiber optic connections urgent.
At present, the plugging and unlocking actions of the optical fiber connector and the corresponding adapter are complex, the size is large under the condition of the same core number, and the operation can be implemented only by needing larger operation space, so that great difficulty is brought to the wiring of the current high-density data center.
The fiber transceiver module commonly used in the market at present may include two optical fiber connectors that are plugged (one for receiving and one for transmitting). With the great increase of transmission rate, dense transmission of multiple ports at the same time can be a trend of applications. With the wide use of WSS and related supporting devices, the application of supporting OXC adapter boxes is increasing, and the use of more connection ports in a smaller-sized space has more and more urgent needs for high-density, subminiature connectors and adapters.
In view of the above application environments, manufacturers are continuously researching smaller fiber optic connector and adapter structures. To accommodate the increasing demand for high-rate, high-bandwidth communications. Under the data center computer lab that satisfies high density walks the fine environment of line cloth, need guarantee the security and the convenience that easy operation nature, stability and reliability after the adaptation, unblock break away from of optical fiber connection.
In high density data center rooms or high density fiber optic adapter panels where a fiber optic connector or adapter is forced to lock or unlock it, adjacent connectors, adapters, cable assemblies, etc. may interfere with individual access to the location where the force is required (conventional LC, FC, SC, etc. connector types). There is a great risk of touching other components, which may potentially risk other connector ribbons being pulled off, over-tensioned, core insert misplaced, cracked, etc., damaging the port or resulting in reduced reliability. More serious may result in some port signal interruptions and once these occur, it will cause great difficulty for the service personnel, who cannot detect the potential risk by reliable means. Assuming that the operator uses a tool to assist with the plug-in connection, the operator may be out of sight of the operator and using the tool to operate will increase the operational time to put in and take out the tool, increasing labor costs, tool design costs, time costs.
