Abstract:
Fronthaul monitoring systems and methods include a Radio Frequency (RF) analysis module configured to receive an optical RF signal for RF testing thereof; a fiber monitoring module configured to perform fiber monitoring testing; an optical switch configured to switch a port connected to the RF analysis module and the fiber monitoring module between one or more Remote Radio Heads (RRH); and a test coordinator software module configured to coordinate the RF testing and the fiber monitoring testing. The optical RF signal is at different wavelengths than a fiber test signal for the fiber monitoring testing, such that the RF testing and the fiber monitoring testing can be performed concurrently.
