Abstract
The application discloses an optical network planning method for asymmetric traffic transmission over a multi-core fiber optical network and a network using the same. The method comprises: acquiring an asymmetric traffic demand over a multi-core fiber optical network to obtain a target service; establishing a corresponding route depending on the target service, and selecting cores in a multi-core fiber and allocating corresponding frequency slots in an interleaving and counter-propagating manner to each link along the route to optimize optical network planning and design. With the method provided by the application, through selecting cores in a multi-core fiber and allocating corresponding frequency slots in an interleaving and counter-propagating manner to each link along the route, the inter-core crosstalk is suppressed and network capacity efficiency is increased, thereby optimizing optical network planning and design for traffic transmission over the multi-core fiber optical network.
