The installation of an OSP fiber optic cable is conventional, underground, direct buried or aerial to the tower and terminated at the base using the hardware for the BBU. This technology is used to enhance the performance of mobile communication networks, particularly in areas where there is high data traffic. In simple terms, Fiber-to-the-Antenna (FTTA) is a broadband network architecture that uses optical fiber to connect the Remote Radio Head (RRH) to the base station instead of coax cables. Important components such as remote radio units (RRUs) are also positioned at the top of the tower instead. The BBU centralizes the “baseband,” “transmission,” “main control,” “clock,” and other functions of the base station. On the other hand, the RRU focuses on the radio frequency (RF) equipment, including the transceiver and RF devices.
