Fiber Optic Solution





In this method, RF signals are converted to optical signals before being transmitted to distribution units via optical fibers. Single-mode and multi-mode fibers can be used but multi-mode fiber requires frequency conversion before RF- to-optic conversion. The fiber optic solution is ideal for wide-area deployments such as in buildings with extensive floor areas and high-rise office buildings. The installation cost can be well contained if the existing optical fiber infrastructure within a building can be re-used. This solution is also useful for expanding on an existing distributed antenna system that is operating on coaxial solutions. Little disruption is imposed on the existing network in this case because only a small signal (tapped out using an imbalance coupler) is necessary to drive the fiber network. Monitoring of the system is achieved through sending back a signal via the BTS to the OMC.
