摘要： A linear N×N robotic fiber optic switch is described. Notably, fiber adapters for connecting the input and output fibers are arranged linearly. Moreover, each fiber adaptor is driven by a push-pull mechanism such that it can be positioned to a front, center, or back position, with which the private plane of a fiber port can be separated from the other fiber ports and fiber connection can be configured using a simple linear translation robotic pickup free of interference in a compact space. Furthermore, a large scale fabric switch comprises 3 stages of N linear N×N robotic switches connected using fiber shuffles. Each stage or all three stages can share one robot to reduce cost. Scalability to large port counts may be accomplished proportional to N, the number of ports, rather than N2.

摘要： The present application provides a data phase recovery method, system, device and storage medium for burst code stream. The method includes: in case of detecting that data burst transmission occurs on a target peer device and detecting that a data pause signal is in an invalid state, increasing a data transmission bandwidth within a preset time specified in a transmission protocol, until a clock and data recovery (CDR) completes data locking; reducing the increased data transmission bandwidth after detecting that the CDR completes data locking. In the embodiment of the present application, by combining fast locking and slow tracking, the data transmission bandwidth is only increased within the preset time specified in the protocol, rather than continuously increasing the bandwidth, which will not have a significant impact on the stability of the link.

摘要： A first optical routing device that includes a mounting component and an optical routing component attached to the mounting component. The mounting component includes a rechargeable battery to power operations of the first optical routing device and a processor that communicates over-the-air with a master communication device or one or more service communication devices via RF supervisory links. The processor receives an instruction via the RF supervisory links to control a movement of the mounting component along with the optical routing component such that an angle or a direction of deflection of laser beams from an optical routing component of optical routing device is changed. The processor performs a range measurement to compute a distance between the first optical routing device and an optical node. The optical node is one of a second optical routing device, the master communication device or one of the one or more service communication devices.

摘要： The present disclosure describes a network including two levels of switching: a first level including wavelength selective switching via a first type of switching module, and a second level including fiber level switching via a second type of switching module. The two levels of switching allow for maintaining wavelength selective switching between transmission directions while introducing fiber selective switching between network degrees of the same transmission direction. The first type of switching module is configured to transmit and receive optical signals having a first set of wavelengths at a first network degree at a first direction in a node of a network. The second type of switching module is configured to transmit and receive the optical signals from the first type of switching module and route the optical signals at the first network degree to a second network degree in a second direction.
