1. A storage area network extension, comprising:
- a storage terminal coupled to a remote node, the remote node being connected to a passive optical network (PON) for transferring data signals in the PON and storage signals to/from the storage terminal by employing subcarrier channels in the PON to enable concurrent bidirectional transfer of the data and the storage signals; and
a storage area network coupled to the storage terminal and configured to store and retrieve the storage signals for transfer over the PON.

Abstract
A storage area network extension, network and method include a storage terminal coupled to a remote node. The remote node is connected to a passive optical network (PON) for transferring data signals in the PON and storage signals to/from the storage terminal by employing subcarrier channels in the PON to enable concurrent bidirectional transfer of the data and the storage signals. A storage area network is coupled to the storage terminal and configured to store and retrieve the storage signals for transfer over the PON.
