1. A system for routing signals in a Distributed Antenna System (DAS), the system comprising:
- one or more local Digital Access Units (DAUs) located at a local location, each of the one or more local DAUs being coupled to each other and operable to route signals between the one or more local DAUs and including an optical port coupled to an upstream unit; and
one or more remote DAUs located at one or more remote locations, wherein the one or more remote DAUs are coupled to the one or more local DAUs via one or more optical cables.

Abstract
A system for routing signals in a Distributed Antenna System (DAS) includes one or more local Digital Access Units (DAUs) located at a local location and one or more remote DAUs located at one or more remote locations. Each of the one or more local DAUs includes an optical port coupled to an upstream unit. The upstream unit includes at least one of a repeater, a baseband unit, a Base Transceiver Station (BTS), or a DAU. The one or more remote DAUs are coupled to the one or more local DAUs via one or more optical cables. A distance between the local location and each of the one or more remote locations is greater than two kilometers.
