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: A rigid composite panel 10 for insulating an installation such as a furnace or cooler (HVAC units). The panel 10 has a thermally insulating core 20, at least two laminate assemblies 30 which are bonded to the core 20 thus forming a sandwich, and an edge band 40 adhesively applied to the edges of the sandwich 50 so as to provide a smooth, continuous, and impermeable seal around said edges. There is also claimed a method for manufacturing a rigid composite panel 10 having an edge band 40, each laminate assembly being pretreated by plasma before the edge band 40 is bonded to the panel 10. Each laminate assembly 30 consists of a thin layer of polymer 38, as well as sheets 36 bonded to the surfaces of the layer 38.
