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.

Abstract: Fronthaul monitoring systems and methods include a performing protocol testing, via a protocol layer acquisition module, of a protocol layer signal for analysis thereof to identify issues; performing optical physical layer monitoring via an optical physical layer acquisition module to identify optical physical layer issues; and configuring an optical switch to switch an input port connected to the protocol layer acquisition module and the optical physical layer acquisition module over different links of the plurality of links wherein a test coordinator software module is configured to manage the optical switch to coordinate the optical protocol layer analysis of a link and the optical physical layer testing of the link.
