1-channel telephone + 1/2/4-channel 1000M Ethernet over Fiber Optic Multiplexer (RJ11 interface) is a product developed by Beijing Fibridge Co., Ltd.
1-channel telephone + 1/2/4-channel 1000M Ethernet over Fiber Optic Multiplexer (RJ11 interface) is a product developed by Beijing Fibridge Co., Ltd. using large-scale integrated circuits with independent intellectual property rights. It applies time-division multiplexing technology to mix and encode Ethernet signals and telephone signals for transmission over a single optical fiber. It enables the mixed transmission of 10/100/1000M Ethernet services and voice channel services, with the transmission channel being optical. This device features a desktop design, high integration, compact size, low power consumption, reliable operation, and convenient installation and use.
