The system includes first and second cable landing stations coupled to a trunk path in an optical cable. At least one hub-node is coupled to the trunk path through an associated hub-node branching unit. In an embodiment, mid-nodes are coupled the hub-nodes through associated mid-node branching units and mid-node paths in the optical cable. Mid-node signals may be communicated between the mid-nodes and the hub-nodes without being provided on the trunk path. Sub-nodes are coupled to at least one of the mid-nodes through associated sub-node branching units and sub-node paths in the optical cable.
