Problems solved by technology

On the one hand, this requires strengthening the inspection of PCBA objects to prevent mixing materials, which will lead to an increase in management costs; on the other hand, different application requirements and different chip installations require manual soldering by production employees. The possibility of causing product quality problems will lead to an increase in production costs

Embodiment Construction

[0042] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0043] Any feature disclosed in this specification, including any appended claims, abstract and drawings, may, unless expressly stated otherwise, be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0045] Such as figure 1 Shown is a schematic diagram of a circuit structure of a typical limiting amplifier chip in an optical module. The optical module converts the optical signal into a current signal through a photodiode, and then converts the current signal into a voltage signal through a transimpedance amplifier. The...

Abstract

The invention discloses a device and method for processing warning signals and enabling signals of a limiting amplifier chip. The warning signals and the enabling signals according with external application requirements are obtained by adding a programmable logic device unit beside the limiting amplifier chip and using the programmable logic device unit to process the warning signals which are not processed step by step, and then unification and fixation on hardware are realized to ensure that complex and disordered situations of raw material purchase and material management of optical model manufacturers are reduced, the management cost is greatly saved; and meanwhile, the flow of manually welding a chip external circuit is eliminated, the production cost is saved, the product quality problems caused by unskilled new employees are solved, and the product quality is improved.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to a device and method for processing alarm and enable signals of a limiting amplifier chip used in an optical module. Background technique [0002] The transmission lines used in the traditional communication field are all copper core cables, which have low transmission efficiency and poor anti-electromagnetic interference ability. Due to the characteristics of high transmission efficiency and strong anti-electromagnetic interference ability of optical fiber, with the improvement of communication transmission rate and the improvement of modern manufacturing process, the cost of optical fiber manufacturing has been reduced, and more and more modern communication fields use optical fiber for communication. Transmission of Information. The optical communication network is connected to the access network of the user terminal, and can be divided into AON (Active Optical Network, a...
