The application discloses a kind of based on FPGA's multi-protocol routing cross device and method, belong to communication technical field, the device includes: adaptive input identification locking unit respectively receives the data of different protocol type, data is adapted to frequency by dynamic switching state machine, pass through protocol locking mark identification to identify specific frame and distribute data type code;High-speed clock domain transition unit writes data and data type code in FIFO, when reaching half full, data is read using high-speed clock and adds valid mark;Cross configuration unit according to configuration information, data and valid mark and data type code are crossed;Adaptive output unit carries out output end SERDES frequency configuration, the phase of SERDES output clock is adjusted based on digital phase-locked loop using valid mark and high-speed clock, constructs sending clock, and data is output on sending clock from high-speed clock transition.The application realizes the routing cross function of multi-protocol with less FPGA logic resource and more optimal timing.

Embodiments of the present application provide an optical cross module, an optical cross device and a data center, aiming to realize optical path switching between an input fiber array and an output fiber array. The optical cross module provided by the present application comprises an optical switching array, the optical switching array comprises a plurality of switching layers arranged in a stack, each switching layer comprises a plurality of optical switches, the optical switch comprises a polarization conversion component and a liquid crystal prism; the liquid crystal prism comprises a first liquid crystal layer with gradually decreasing thickness, after being selected by the polarization conversion component, the light beam with the first polarization direction or the second polarization direction enters the first liquid crystal layer; the first liquid crystal layer refracts the two light beams with different polarization directions at different angles, so that the light beam after the polarization conversion component has the first polarization direction or the second polarization direction can be controlled to control the light beam to be shot from the first optical path to the port or from the second optical path to another port, thereby realizing the optical path switching between the input fiber array and the output fiber array by the optical cross module.

To provide a swap cross device. [Solution] A device that, upon receiving instructions for a swap contract, publicly announces the potential cross of the swap contract to all multiple market participants in the trading venue, inputs first information indicating the passage of time in a first period into the user interface, disables the function on the user interface for sending a request for a cross during the first period, inputs second information indicating the passage of time in a second period after the first period into the user interface, enables the function on the user interface for sending a request for a cross during the second period, determines that for either of the two parties, there is no price in the market better than the price of the request for a cross, determines that there is a price in the market equal to the price of one of the two parties which has a higher temporal priority than the request for a cross, and facilitates the execution of a cross between the two parties.
