The intelligent fiber near-end machine converts the electrical signal into an optical signal and transmits it to the intelligent fiber remote repeater through the optical fiber. The intelligent fiber remote repeater converts the optical signal transmitted by the optical fiber into a radio frequency signal and amplifies it. The equipment takes advantage of the long-distance transmission of light to achieve indoor coverage of the remote area of ​​the wireless intercom system. The optical transmission technology adopts advanced wavelength division multiplexing technology (WDM) and uses the same optical fiber to transmit both upstream and downstream signals. The equipment adopts a comprehensive detection circuit design to realize comprehensive data detection and data upload functions of the equipment, and realizes linkage with the Netcom cloud platform to remotely manage the equipment.
