32-channel telephone + 1/2/4-channel 1000M Ethernet over Fiber Optic Multiplexer (RJ11 interface) is a product developed by Beijing Fibridge Co., Ltd.
32-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 1U chassis design, high integration, compact size, low power consumption, reliable operation, and convenient installation and use.
1. Provides 1 channel optical port(speed rate 1.25G)
2. Provides 32 channel telephone(Optional from Magneto and hotline)
3. Provides 1/2/4 channel 10/100/1000M Ethernet ports
4.Built-in power adapter(220V or DC48V)
5. Single or dua fibers for options. Default is single fiber.
6. Optical transmission distance is SM20km, up to 120km
7. 1U chassis device.
