ABSTRACT:
A system and method for linking optical wavelength division multiplexed (OWDM) networks by using wireless communications. Each optical channel in a OWDM network is coupled to a wireless wavelength division multiplexing (WWDM) channel by a WWDM transceiver, which transmits and receives data between OWDM networks. The WWDM transceiver may transmit and receive data in RF bands, where the assignment of different OWDM channels to different frequencies within the RF bands may depend upon the data rate or service supported by the OWDM channel. WWDM systems may also support communications between OWDM networks and individual users, such as those in a local multipoint distribution service.
