摘要： A flexible grid optical network in which a first network terminal is connected to a second network terminal using a main optical fibre connection and a protection optical fibre connection, wherein the protection optical fibre connection is longer than the main optical fibre connection. A first optical signal is sent over the main optical fibre connection and comprises one or more flexible grid sub-channels. In the event of a failure of the main optical fibre connection, a second optical signal is sent over the protection optical fibre connection. If the length of the protection optical fibre connection is greater than the reach of the flexible grid sub-channels that comprise the first optical signal then the second optical signal will comprise a greater number of flexible grid sub-channels: these sub-channels will have lower data rates but a longer reach and will provide the necessary capacity over the protection optical fibre connection.
