Abstract: Provided are a forced protection switching method and a forced protection switching clearing method in an Ethernet ring network. When an operator desires to block a port of a specific node for maintenance and repair, the operator gives a forced switching (FS) command to the specific node in order to block the port. When the operator desires to clear FS, the operator gives a clear command to the specific node in order to clear the blocked port. As a result, operation flexibility of the Ethernet ring network is provided.

Abstract: In a wireless optical communication system in which communication is performed based on a free space and a plurality of the communication apparatuses are arranged in a ring form around a central office terminal (COT), the communication apparatus monitors optical signals received in a first direction or in a second direction opposite to the first direction, and selects a first path through which the optical signals in the first direction are received and a second path through which the optical signals in the second direction are received. The communication apparatus converts an optical signal having a predetermined unique wavelength from among the optical signals received through the selected path into a signal of a frequency domain having a plurality of subcarriers, and obtains packet data mapped to each of the subcarriers.
