Abstract
A method and system for bandwidth efficient optical transport in radio access networks using radio-over-fiber optical transport may directly transmit radio access signals over an optical fiber by frequency multiplexing multiple parallel streams of digital wireless signals into a serial stream of optical digital subcarrier signals. A radio-over-fiber transceiver to enable efficient optical transport in radio access networks may be implemented on remote radio head and baseband unit equipment as a plug-in digital coherent optics module or as an on-board internally mounted digital coherent optics module.
