The world is becoming digital, the world is becoming connected. At the end of year 2018, 55.1% of the worldwide population is using internet  while 36% is using smart phones , and the number keeps growing. This together with the explosion of hot topics like “Big Data”, “Cloud Computing”, “Artificial Intelligence”, “Internet of things” in the recent years , generating intensive demands on data transmission in terms of speed and coverage. Massive infrastructures, e.g. base stations, data centers have been built and under construction all over the world to adapt this trend. However, building new infrastructures costs time and money, upgrade from existing infrastructures in most cases seems more optimistic way.
MPO solution has been widely used in data centers and large enterprises due to its simple plug-and-play installation nature. For 10G MPO configuration, three methods are introduced in the ANSI/TIA-568 standards, i.e. “Method A”, “Method B” and “Method C”. “Method A” needs both straight and cross patch cords, while “Method B” if without any modification, will give very confusing port correspondence at the near and far ends. Due to simple components management and straight forward port correspondence, “Method C” is chosen predominantly as the preferred 10G MPO configuration method. Nevertheless, it will cause problem if using the same backbone cables to migrate to 40G MPO channel, as “Type C” MPO trunk cables can hardly be used for 40G application. What if you still want to use the existing “Type C” MPO trunk cables to upgrade to 40G?
In this white paper, the methods to migrate from existing 10G “Polarity C” MPO channel to 40G MPO channel will be discussed in three different initial scenarios. For more details, please refer to the white paper below.
