Provided is a few-mode optical fiber. The optical fiber includes: a core and a cladding enclosing the core. The cladding includes: a first inner cladding surrounding the core; a first high-refractive-index mode filter layer surrounding the first inner cladding; a second inner cladding surrounding the first high-refractive-index mode filter layer; a second high-refractive-index mode filter layer surrounding the second inner cladding; and an outer cladding surrounding the second high-refractive-index mode filter layer.

Few-mode optical fiber

Embodiments of the present invention provide a method and an apparatus for data quality management and control. The method includes: receiving application information transmitted by a service sub-system; resolving datasheet operation trigger information to obtain datasheet flow information; receiving user information transmitted by the service sub-system and a target datasheet transmitted by the service sub-system; if a name of the target datasheet is different from a plurality of datasheet names corresponding to the service sub-system identifier, then instructing the service sub-system to store the target datasheet into a data center; if the datasheet operation information is updating a datasheet, instructing the data center to replace datasheet contents corresponding to the datasheet name with contents of the target datasheet.

Method and apparatus for data quality management and control

A highly available server system based on cloud computing comprises a central control management server, a cloud host server, a storage server and at least one application server; the central control management server is connected with at least one application server, and configured to respectively monitor at least one application server, if detecting that there exists an application server in the fault state among the at least one applications server, then the central control management server sends a first instruction message; the cloud host server is connected with the central control management server, and configured to receive the first instruction message, and call the target virtual machine image file from the storage server according to instructions of the first instruction message, and run the target virtual machine image file; the storage server is configured to store the corresponding virtual machine image file of at least one application server.
