Abstract

The invention discloses a centralized gigabit Ethernet optical transceiver, and the optical transceiver comprises a main control unit, an E1 unit, an Ethernet unit, a telephone unit and an optical module interface device. The main control unit comprises a main control chip, a clock signal jitter attenuation chip, a power-on reset device, a clock attenuation signal configuration module and a dial switch module. The main control chip is respectively connected to the E1 unit, the Ethernet unit, the telephone unit, the optical module interface device, the clock signal jitter attenuation chip and the dial switch module. The clock signal jitter attenuation chip is connected to the clock attenuation signal configuration module and the power-on reset device. The clock attenuation signal configuration module comprises a plurality of anode resistors and cathode resistors, and each signal pin of the clock signal jitter attenuation chip is connected to the VCC power supply end through one anode resistor and is grounded through one cathode resistor. The optical transceiver is high in integration level, and the modular design is adopted to achieve the effects of easy capacity expansion and easy upgrading.

Description

technical field [0001] The invention relates to an optical transceiver, more specifically, it relates to a centralized Gigabit Ethernet optical transceiver. Background technique [0002] The optical transceiver is a physically isolated Ethernet optical fiber transmission device developed for systems such as high-definition network cameras and network access control. Apply 1.5G / 2.5G / 3.125G transmission rate and CWDM (Coarse Wavelength Division Multiplexer, Dense Wavelength Division Multiplexing) technology to realize the hybrid of Gigabit / 100M line-speed Ethernet data channel, video, and asynchronous data RS485 / 422 / 232 multiplexing and transmission. It can meet the needs of operators' key customers and private network users for different levels of bandwidth and multi-service access. The current optical transceivers have problems such as unreasonable circuit design, low integration and large space occupation. Contents of the invention [0003] Aiming at the shortcomings o...
