  • How is the fiber optic cable connected to BBU

    How is the fiber optic cable connected to BBU

    A CPRI link connects the baseband processing side of a mobile base station to the radio side. In traditional deployments, this means a fiber connection runs from a BBU - often housed in an equipment room or shelter - to one or more RRUs mounted on a tower, rooftop, or pole. On the other hand, the RRU focuses on the radio frequency (RF) equipment, including the transceiver and RF devices. Via optical fiber The RRU connects to the BBU, forming a new. Connection to Antenna: The RRU connects to the antenna via jumper cables (coaxial cables), which are responsible for transmitting RF signals. The Battery Backup Unit (BBU) provides power so that you will be able to make any calls from your home phone. This type is a BBU at the Optical Network Terminal (ONT).
