The method includes: performing forward error correction FEC encoding processing on at least one to-be-sent bit data stream, to obtain M first encoded data streams, where M is an integer greater than 1; and performing first data processing on the M first encoded data streams, to obtain W first dual-polarization symbol data streams, where W is an integer greater than 1; each of the W first dual-polarization symbol data streams is located in two orthogonal polarization directions; the first data processing includes symbol mapping processing; in one polarization direction, P consecutive symbols in the first dual-polarization symbol data stream are obtained by performing symbol mapping processing on q×P bits, and the q×P bits are from at least two of the M first encoded data streams, where P is an integer greater than 1, and q is a positive integer.

Abstract: In an example method, probabilistic constellation shaping (PCS) processing is performed on a first bit set in k bits, to obtain a second bit set. Forward error correction (FEC) encoding is performed on the second bit set and a third bit set in the k bits excluding the first bit set, to obtain a fourth bit set. The fourth bit set includes m0 first bit subsets, and each of the first bit subsets includes F0 bits. First interleaving processing is performed on the fourth bit set to obtain a fifth bit set. The fifth bit set includes m0 second bit subsets, each of the second bit subsets includes F0 bits, F0/2 bits in each of the second bit subsets are from the second bit set, and the other F0/2 bits in each of the second bit subsets are from the third bit set and/or parity bits of the FEC encoding.

Abstract: Distributed system resources may be managed by applying user created policies to the resources. To ensure that valid policies are applied, remote validation for the policies may be implemented. A validation event for a policy may be detected. A remote validation agent may be identified for the policy and a validation request sent to the remote validation agent that includes information for validating the policy. The remote validation agent may return a validation result for the policy. If valid, a policy action that triggered the remote validation event for the policy may be allowed. If invalid, the policy action that triggered the remote validation event for the policy may be denied.

Abstract: Multiple edits to a hierarchical data structure may be atomically applied. A request to perform modifications with respect to a portion or the entire hierarchical data structure may be received. A copy of the requested portion of the hierarchical data structure may be created separate from the hierarchical data structure. The portion of the hierarchical data structure may remain available for read access. Modifications may be applied to the copy of the portion of the hierarchical data structure. In response to a request to commit the modifications to the portion of the hierarchical data structure, the copy of the portion of the hierarchical data structure may atomically replace the portion of the hierarchical data structure.

Abstract: Resource data objects describing resources in a system may be maintained in multiple different hierarchies for applying policies to manage the resources. Lookup requests may access the different hierarchies to determine which policies are applicable to a given resource based on the policies identified in each of the hierarchies. Modifications to hierarchies may be performed in isolation so that the application of policies in other hierarchies is unchanged by modifications to a different hierarchy. Access restrictions may be enforced with respect to hierarchies so that different users may be permitted access to different hierarchies for system resource management.

Abstract: A connector assembly includes a connector and a fixing device. The connector has a housing, a ferrule mounted in the housing, and a rear body inserted into a rear end of the housing. The fixing device is connected to the rear body of the connector. The fixing device has a fixture formed in a single integrated piece. The fixture includes a connection part located at a front end of the fixture and configured to be connected to the rear body of the connector and a flexible protection part disposed adjacent to the connection part and configured to protect a cable passing therethrough.

Abstract: This application provides a mode division multiplexer, which includes a metasurface of an electromagnetic resonance unit that has a plurality of sub-wavelengths disposed in an array. The electromagnetic resonance unit is configured to perform phase modulation on a beam transmitted to the electromagnetic resonance unit, to convert a spatial mode order of the beam. Because a size of the electromagnetic resonance unit is a sub-wavelength, and a pixel size of the electromagnetic resonance unit is smaller than a pixel size of a spatial light modulator in the prior art, crosstalk between different spatial modes after phase modulation performed by the mode division multiplexer is comparatively low. In this way, the crosstalk is comparatively small when beams in different spatial modes are multiplexed into a few-mode/multi-mode fiber. The mode division multiplexer in this application can implement polarization-independent phase modulation.

The second sleeve is threaded onto the first thread portion at a second end of the second sleeve. The clamp mechanism clamps the cable in response to an engagement of the second end of the second sleeve to the first thread portion to prevent the cable from moving in the first sleeve and the second sleeve.

Abstract: A near-eye display (NED) has an orientation detection device and a display block. The orientation detection device collects orientation data that describe an orientation of the NED. The display block has a display assembly, a focusing assembly, and a controller. The controller determines an orientation vector of the NED based in part on the orientation data and computes an angular difference between the orientation vector of the NED and a gravity vector. After comparing the angular difference to a threshold value, the controller generates multifocal instructions that adjusts the optical element to display an augmented scene at the selected image plane corresponding to the multifocal instructions.
