Abstract:
1. A stabilizing method for a signal transmission from a transmission optical cross-connect (OXC) to a receiving OXC in an optical network, in which a plurality of OXCs each having a plurality of optical receivers and optical transmitters are connected to each other through optical lines, the method comprising the steps of: determining by an OXC of a transmission rate that corresponds to a transmission speed of an inputted signal; stabilizing a predetermined optical receiver, that converts the inputted signal into an electric signal and a predetermined optical transmitter that converts the electric signal into an optical signal, through use of the determined transmission rate; transmitting the determined transmission rate into an adjacent OXC by the transmission OXC, wherein an adjacent OXC is one of said plurality of OXCs that is directly connected to another of said plurality of OXCs through an optical line; receiving the transmission rate provided from the transmission OXC by the receiving OXC and a relay OXC aligned in a route, through which the signal is transmitted to the receiving OXC from the transmitting OXC; and determining the received transmission rate as a transmission rate for stabilizing the predetermined optical receiver and the predetermined optical transmitter by the receiving OXC and the relay OXC aligned in the route.
