Abstract: Provided is an optical fiber adapter. The optical fiber adapter includes an adapter body, a shielding gate, a sleeve, and an elastic shield. One side wall of the adapter body is provided with a long groove. The shielding gate is disposed at a lower port of the adapter body. The shielding gate includes one end connected to the lower port of the adapter body and one end facing away from the lower port of the adapter body. The sleeve is sleeved on a periphery of a lower end portion of the adapter body. The elastic shield is disposed in the long groove. The elastic shield is fitted with one end portion of the shielding gate facing toward the elastic shield. The shielding gate, the sleeve, and the elastic shield form an anti-light-leakage cavity on an optical fiber access side of the optical fiber adapter.

Abstract: Systems and methods for role-based access control for a storage system are described. An illustrative method includes an access control system identifying, based on a role of a user requesting access to the storage system, a permission of the role to access a resource type; determining, based on the resource type and on a mapping of resources of different secured endpoints of the storage system to resource types, a set of resources of the storage system that the role has permission to access; identifying a subset of the set of resources of the storage system that the user is authorized to access; and granting the user role-based access to the subset of the set of resources of the storage system.

Abstract: A continuous operation method is employed for the microwave high-temperature pyrolysis of a solid material containing an organic matter. The method includes the steps of mixing a solid material containing an organic matter with a liquid organic medium; transferring the obtained mixture to a microwave field; and in the microwave field, continuously contacting the mixture with a strong wave absorption material in an inert atmosphere or in vacuum. The strong wave absorption material continuously generates a high temperature under a microwave such that the solid material containing an organic matter and the liquid organic medium are continuously pyrolyzed to implement a continuous operation.

Abstract: A grafted polypropylene resin is prepared by a grafting reaction of a polar monomer capable of absorbing microwave so as to raise its temperature in a microwave field to more than 200° C. and a solid polypropylene resin using microwave irradiation without adding an initiator. The polar grafted polypropylene resin that does not contain initiator residues and does not have a significant reduction in molecular mass compared with a resin before grafting is obtained.

Abstract: The invention discloses a multi-plug DC charging pile system, the number of whose charging modules can reach more than 6, while the number of plugs is only half of the number of charging modules. Each charging module can be switched to any plug. At the same time, the economy, practicability and stability of the product are improved. The multi-plug DC charging pile system includes: six DC charging modules, three plugs, a main control board, a switching control board and sixteen DC contactors. The main control board controls the output of six DC charging modules through CAN. The main control board is connected with the switching control board. The main control board is connected with three plugs through CAN. The sixteen DC contactors are connected with one of three plugs respectively. The switching control board controls the on-off of sixteen DC contactors to control the DC charging power obtained by three plugs.

Abstract: An LC adapter provided with a built-in light shielding plate includes a frame. One end of the frame is provided with interfaces for matching with connection members. An upper light shielding plate and a lower light shielding plate in a spliced connection with each other are disposed at a position within the frame close to the interfaces. Both the upper light shielding plate and the lower light shielding plate are hingedly connected to the frame through a return spring. When a connection member is inserted into an interface, the upper light shielding plate and the lower light shielding plate rotate relative to the frame and are separated from each other. When the connection member is unplugged from the interface, the upper light shielding plate and the lower light shielding plate are restored to the state of the spliced connection with each other.

Abstract: An LC adapter provided with a built-in light shielding plate includes a frame (1). One end of the frame (1) is provided with a plurality of interfaces (11) for matching with connection members. An upper light shielding plate (2) and a lower light shielding plate (3) in a spliced connection with each other are disposed at a position within the frame (1) close to the interfaces (11). Both the upper light shielding plate (2) and the lower light shielding plate (3) are hingedly connected to the frame (1) through a return spring (4). When a connection member is inserted into an interface (11), the upper light shielding plate (2) and the lower light shielding plate (3) rotate relative to the frame (1) and are separated from each other under the acting force of the connection member.

Abstract: A LC-typed duplex connector includes a connecting head assembly, a boot assembly and a handle. The handle includes a first elastic structure portion, a second elastic structure portion and a hand shank portion. When the second elastic structure portion is detached from the boot assembly, the first elastic structure portion is detached from the connecting head assembly under the action of the hand shank portion, achieving the detachment and alternate side operation of the LC-typed duplex connector. The detachable handle can efficiently fasten the connecting head assembly with the boot assembly together. The first and second elastic structure portions are easier to detach from the connecting head assembly and the boot assembly respectively under the action of the hand shank portion. Moreover, the hand shank portion is matched with the tail end of the boot assembly, thereby improving efficiently the space utilization of the panel.
