Description
Technical Field
The utility model relates to a network communication technology, in particular to a household optical fiber hub.
Background
The optical modem, also called optical modem or single port optical transmitter and receiver, is a three-piece optical fiber transmission equipment developed for special user environment, and the equipment adopts large scale integrated chip, and has simple circuit, low power consumption, high reliability, complete alarm state indication and perfect network management function. The optical modem is composed of transmitting, receiving, controlling, interface and power supply. The data terminal equipment provides the transmitted data in the form of binary serial signal, converts it into internal logic level via interface and sends it to the transmitting part, and modulates it into the signal required by the line via modulation circuit and sends it to the line. The receiving part receives the signal from the line, and the signal is restored into a digital signal after filtering, inverse modulation and level conversion and then is sent to the digital terminal equipment. Similar to the modulation and demodulation of high frequency carriers in electrical communication, optical modems can modulate and demodulate optical signals. An electrical signal with information input to an optical transmitter, whether an analog system or a digital system, is converted into an optical signal by modulation. The optical carrier is transmitted to a receiving end through an optical fiber line, and then the optical signal is converted into an electric signal through demodulation by a receiver.
The Optical modulator is an E/O (Electro-Optical conversion) component consisting of a microwave packaged high-frequency DFB (Distributed Feedback Laser) Laser diode, an APC (automatic power control) circuit and an ATC (automatic temperature control) circuit, directly modulates the ultrahigh-frequency Laser diode by using a radio-frequency microwave signal to generate an intensity modulation Optical signal, then couples the intensity modulation Optical signal into a single-mode Optical fiber, transmits the intensity modulation Optical signal through about 5km of the single-mode Optical fiber, receives the intensity modulation Optical signal by an Optical demodulator to complete O/E (Optical/electrical) conversion, and consists of a PD component of a high-speed trans-impedance amplifier and a broadband low-noise amplifier.
