Abstract

The invention provides an automatic debugging method for an optical eye diagram of an optical module. In the method, threshold current of a laser is obtained firstly and bias current of the optical module is set as the sum of the threshold current and a balance coefficient by a computer, so that the optical eye diagram is debugged automatically without artificial debugging; and Compared with the prior art, the method can prevent the influence of subjective factors of human on quality, realize debugging without using expensive data analyzers and reduce production cost simultaneously.

Description

technical field [0001] The invention relates to a debugging method, in particular to an automatic debugging method for an optical eye diagram of an optical module. Background technique [0002] The traditional method of debugging the optical eye diagram of the laser in the optical module is to use the mechanical or digital potentiometer inside the optical module to manually adjust the working point of the laser, so that the technical indicators of the optical eye diagram: extinction ratio (EXTRATIO) and cross point (CROSSING) fulfil requirements. [0003] When using the manual adjustment method, while the operator manually adjusts the value of the potentiometer, his eyes should also be fixed on the changes of the two data of the extinction ratio and the intersection point analyzed by the data communication. Because even the same batch of lasers may have different operating points. Therefore, the value of the potentiometer is also different. Sometimes it is necessary to ad...
