The Splitter/Combiner Panel is used to interconnect all RF paths in a Fiber-DAS head-end system. The unit consists of four strips of splitter/combiner ports with one common and 8 isolated ports in each strip. The unit is used to interconnect between the base station interface unit and the fiber optic interface and to split the signal on to several fiber-optic (FOI) interfaces.
