Abstract

Unified optical fiber-based distributed antenna systems (DASs) for supporting small cell communications deployment from multiple small cell service providers are disclosed. The unified optical fiber-based DASs disclosed herein are configured to receive multiple small cell communications from different small cell service providers to be deployed over optical fiber to small cells in the DAS. In this manner, the same DAS architecture can be employed to distribute different small cell communications from different small cell service providers to small cells. Use of optical fiber for delivering small cell communications can reduce the risk of having to deploy new cabling if bandwidth needs for future small cell communication services exceeds conductive wiring capabilities. Optical fiber cabling can also allow for higher distance cable runs to the small cells due to the lower loss of optical fiber, which can provide for enhanced centralization services.
