Abstract
An optically-switched fiber optic communication system, such as a Radio-over-Fiber (RoF) based optical fiber link system, may be used to increase the range of peer-to-peer communications. The optically-switched fiber optic communication system may include a head-end unit (HEU) having an optical switch bank. Fiber optic cables comprising optical fibers optically couple the HEU to one or more remote access points in different coverage areas. The optical switch bank in the HEU provides a link between the remote access points in the different coverage areas such that devices in the different cellular coverage areas can communicate with each other over the optical fibers through the HEU. By using the optically-switched fiber optic communication system, the range and coverage of communication between devices may be extended such that devices in different coverage areas and devices using different communication protocols can communicate.
