1. A communication station, where the communication station is a first station and comprises:
a first reconfigurable optical add-drop multiplexing (ROADM) device which includes a first port being capable of connecting a cable in a first direction of a network;
a second ROADM device connected to the first ROADM device, which includes a second port being capable of connecting a cable in a second direction of the network, wherein the second direction is different from the first direction; and
an optical protection device;
wherein the optical protection device is respectively connected to the first ROADM device and the second ROADM device, and configured to control the first station to perform communication of a corresponding service with a second station in the first direction corresponding to the first ROADM device, or to perform communication of the corresponding service with the second station in the second direction corresponding to the second ROADM device, and
wherein when a communication abnormality is detected to occur when the communication with the second station for the corresponding service is transmitted in the first direction corresponding to the first ROADM device, the optical protection device is configured to switch the communication in the first direction corresponding to the first ROADM device to the second direction corresponding to the second ROADM device to transmit communication with the second station corresponding to the service.
