Claim Text:
1. A method of retrofitting a remote unit of a Distributed Antenna System to an existing passive optical network including end subscribers coupled to a central office via at least a fiber distribution hub and a drop terminal, the method comprising: providing a distribution cable including a plurality of distribution fibers, each distribution fiber having a first end plugged into a termination field at the fiber distribution hub and a second end coupled to a first output port of the drop terminal, at least some of the distribution fibers being coupled to the central office via a first feeder cable; optically coupling at the termination field a first end of a first of the distribution fibers to a second feeder cable that carries optical signals from a base station so that the optical signals from the base station are carried to the first output port of the drop terminal while another output port of the drop terminal remains connected to one of the end subscribers; and optically coupling the remote unit to the first output port of the drop terminal so that the remote unit receives the optical signals carried to the first output port by the second feeder cable, wherein optically coupling the remote unit to the first output port of the drop terminal includes:
