28G SFP packaged optical module

Abstract

The invention relates to a 28G SFP packaged optical module which comprises a 28G laser device, a 28G optical detector, a micro-controller, an electrical interface circuit, a power source management circuit, an emitting clock recovery circuit, a laser driving circuit, a receiving clock recovery circuit and an amplitude limit amplification circuit. The receiving clock recovery circuit, the emitting clock recovery circuit, the amplitude limit amplification circuit and the laser driving circuit are integrated on an MAX24033 chip; an SFI interface is adopted in the electrical interface circuit. The 28G SFP packaged optical module also comprises a fist power source management circuit and a second power source management circuit that are respectively connected with the 28G optical detector and the 28G laser device, 3.3V input voltage of the module is boosted to 4.5-6V via the first power source management circuit, and therefore that the 28G optical detector works at an optimal performance point can be ensured; the 3.3V input voltage of the module is boosted to 3.5-4V via the second power source management circuit, and therefore suitable working voltage is provided for a driver.

Description

technical field [0001] The present invention relates to the field of optical communication, and more specifically relates to a 28G SFP packaged optical module. Background technique [0002] At present, the connection of wireless access to the 4G network is mainly the interconnection between people. The connection between people and things, things and things, thus forming a broader and open world of the Internet of Things. In order to meet the increasing bandwidth requirements and people's lifestyles, higher connection bandwidth requirements have been proposed, but there is no relevant standard in the industry yet. [0003] With the development of the optical communication industry, there is more and more demand for SFP (Small Form-factor Pluggables, small hot-swappable) products. The SFP optical module is a small hot-swappable optical module that conforms to the definition of the MSA protocol. In the optical communication system, the function of bidirectional data transmis...
