Abstract
A communications system connects one or more BTS hotels with several remote access nodes on a transmission ring. Each operator has one or more separate optical wavelengths. Signal flow around the ring can either be uni-directional or bi-directional. Each optical wavelength (or wavelength pair) contains the wireless signal traffic for all remote nodes in the ring for the operator using that particular wavelength in digital form. At each node, the incoming signals are electrically demultiplexed and appropriate signals for that node are extracted for conversion to RF. These signals are copied rather than cut so that they are also available at following remote antenna nodes, thereby enabling simulcast operation.
