Abstract

The present invention discloses an device for cross protection, including: a service unit source end, configured to map optical data unit (ODUk) signals into the same time slots of n line similar optical transport network (OTN) frame format (OTUxG) data buses, and obtain m+n line OTUxG data through protective coding and then send to a combination cross unit; the combination cross unit, configured to split and recombine the m+n line OTUxG data in the time slot, and then send to a service unit destination end; the service unit destination end, configured to protectively decode the m+n line OTUxG data, recover n line OTUxG data, and extract corresponding ODUk signals from the same time slots of n line OTUxG data. The present invention also discloses a method for cross protection. The present invention implements the cross scheduling of ODUk (k=0, 1, 3) levels, improves the processing efficiency, saves the resources, and also makes the use more flexible and convenient.
