A high speed split receiver interface system for sensing a series of external signals, the system including: a series of remote radio head units for receiving a sensed signal in an analog electric form, each of the remote radio head units converting their sensed signal to a corresponding digital electrical form and then to a corresponding optical data form for dispatch over an optical data interconnection; at least one optical interconnect interconnecting each remote radio head unit with a baseband unit; a first baseband unit interconnecting the series of remote head units corresponding optical interconnects, and including a converter for conversion of the received optical signals to corresponding electrical digital form and down sampling the optical signals to corresponding down sampled signals, a memory store for storing the down sampled signals, and an external network interface for transmission of the saved signals to an external device.
