The transmission optical fiber adopts a single-core optical fiber, and the single-core optical fiber adopts a single-mode transmission method, which is suitable for long-distance and high-speed transmission.

[0039] The emergency routing module includes an adjacent station automatic line and an adjacent station digital modulation line. The input ends of the adjacent station automatic line and the adjacent station digital modulation line are both connected to the adjacent station automatic line and the output ends of the adjacent station digital modulation line are both connected to the voice channel interface 2 of the voice channel unit, and are connected to the downlink optical interface of the local telephone and the uplink optical interface of the adjacent station telephone through the voice channel unit; the emergency routing module does not work when the power is on. When the power is off, the adjacent station automatic line and the adjacent station digital modulation line are manually selected. When the adjacent station automatic line is selected to be connected, the emergency routing module sends an emergency signal, and the emergency signal is transmitted through optical fiber to receive and send automatic telephone signals of the adjacent station; when the adjacent station digital modulation line is selected to be connected, the emergency signal is transmitted through optical fiber to receive and send automatic telephone signals of the adjacent station.

[0040] After power failure, when automatic emergency communication with the neighboring station is required, first manually select to connect the automatic line of the neighboring station and the voice circuit interface 2 of the telephone unit, the emergency signal is sent to the voice circuit unit, the voice circuit unit transmits the emergency signal, the voice circuit unit receives the emergency signal and outputs it to the downlink optical interface of the telephone, the emergency signal received by the downlink optical interface is transmitted to the uplink optical interface of the neighboring station telephone through the transmission optical fiber, because the uplink optical interface of the neighboring station telephone is connected to its telephone unit, and the neighboring station telephone is powered on and can work normally at this time, the emergency signal is received by the telephone unit of the neighboring station telephone, and a control signal is output, thereby controlling the voice circuit interface 1 of the voice circuit unit of the neighboring station telephone to connect with the automatic telephone line of the neighboring station telephone, and an emergency automatic call is dialed with the telephone number of the neighboring station telephone.

[0044] When you want to talk with the neighboring station, choose to connect the uplink optical interface or the downlink optical interface based on the relative position of the neighboring station and this phone on the overall optical fiber voice circuit. At this time, the phone needs to be powered on. After the connection is made, the connection between the two voice circuit units between the neighboring stations is realized through optical fiber transmission. Since the two adjacent phones are powered on, the voice circuit interface 1 of the phone voice circuit unit is automatically connected to the telephone transceiver module, and the telephone transceiver modules and microphone components of the two adjacent phones start to coordinate the call.
