POI(16 IN 4 OUT, Multiband Connector)
In telecommunications a point of interface (POI) is used to show the physical interface between two different carriers, such as a local exchange carrier (LEC) and a wireless carrier, or an LEC and an IntereXchange Carrier (IXC). As the core equipment of multi-network convergence indoor coverage, uses multi-frequency point low-loss combining technology to effectively combine and split the uplink and downlink RF signals of various operators, which can ensure that the system is combined without distortion. The uplink and downlink signals are transmitted, and the signals of each network will not interfere with each other. Multiple systems share an indoor distributed system.
