Medium Power DAS Remotes Units


DDR Series, Remote Units are high performing, wideband amplifiers. An industry leader in DAS solutions, the Bird fiber optic system allows controlling a mixture of remote families (DDR and DDH) from a single Master Unit to reduce the head end footprint and maximize usage of the fiber backbone infrastructure. Multiple frequency bands and amplifiers can be contained in a single chassis.
