Problems solved by technology

However, in burst mode applications, the laser only emits light in a relatively short period of time, and the length of each burst time is different. Therefore, it is necessary to quickly respond to the relative comparison between the output optical power indication and the power level in burst mode. difficulty

Abstract

The invention discloses a 10G single-fiber bidirectional optical module, which comprises a burst laser driver, a burst light power indicator, a microcontroller, a single-fiber bidirectional optical device, an avalanche photoelectric diode bias control circuit, a limiting amplifier, a receiving end light power monitor and an SFP+ connector, wherein the microcontroller is mainly used for controlling the burst laser driver and the limiting amplifier; the single-fiber bidirectional optical device is connected between the burst laser driver and the limiting amplifier to realize conversion between electrical signals and light signals; and the avalanche photoelectric diode bias control circuit supplies a high bias voltage to a receiving end avalanche photoelectric diode and performs voltage compensation on the receiving end avalanche photoelectric diode according to the temperature property. The 10G single-fiber bidirectional optical module has the advantages of low design cost, simple circuit design and capability of meeting the requirement of a 10G EPON ONU symmetrical scheme.

Description

technical field [0001] The invention relates to 10G Ethernet passive optical network (10GEPON) technology, in particular to a high-speed single-fiber bidirectional SFP+ 10G EPON ONU optical module. Background technique [0002] With the promotion and popularization of FTTx (fiber-to-the-user terminal) technology, high-speed broadband services are gradually changing people's life and work styles. SOHO will be very easy to implement, and family high-definition interactive film and television programs, telemedicine, and distance education will not be far away . People's demand for bandwidth continues to increase, making the bandwidth provided by the current 1G EPON technology gradually unable to meet the needs of broadband services. Therefore, the 10G EPON technology that can provide higher bandwidth has become a very attractive solution, and the 10G EPON ONU optical module is an important part of the system. [0003] In optical module applications, the function of detecting ...
