100G optoelectronic PCB is a packaging substrate for a new generation of high computing, which integrates light with electricity, transmits signals with light and operates with electricity. It adds a layer of light guide to the traditional printed circuit board, which is very mature at present.
The pace of the 400g network is getting closer and closer. The domestic Internet giants Alibaba and Tencent plan to start upgrading the 400g network in 2019. The 400G optical module PCB, as the hardware of the 400G network upgrade, has attracted the attention of all parties.
TU-943R PCB - when wiring the multi-layer printed circuit board, as there are not many lines left in the signal line layer, adding more layers will cause waste, increase certain workload and increase the cost. To solve this contradiction, we can consider wiring on the electrical (ground) layer. First of all, the power layer should be considered, followed by the formation. Because it is better to preserve the integrity of the formation.
High-speed PCB digital circuit has high frequency and strong sensitivity of analog circuit. For signal line, high frequency signal line should be far away from sensitive analog circuit device as far as possible. For ground wire, the whole PCB has only one node to the outside world. Therefore, it is necessary to deal with the problem of common ground of digital and analog in PCB, while in the board, digital ground and analog ground are actually separated, and they are not mutually related Connection is only at the interface between PCB and the outside world (such as plug, etc.). There is a little short circuit between digital ground and analog ground, please note that there is only one connection point. Some of them are not grounded on the PCB, which is decided by the system design.
The main function of 40G optical module PCB is to realize photoelectric and electro-optic transformation, including optical power control, modulation and transmission, signal detection, IV conversion and limiting amplification judgment regeneration. In addition, there are anti-counterfeiting information query, TX disable and other functions. The common functions are: SFF, SFF, GBP +, GBIC, XFP, 1x9, etc.
Electronic design is constantly improving the performance of the whole machine, but also trying to reduce its size. From mobile phones to smart weapons, "small" is the eternal pursuit. High density integration (HDI) technology can make terminal product design more miniaturized, while meeting higher standards of electronic performance and efficiency.
