Data center in the end how many optical modules needed

1) Data centers have a variety of architectures, the balance of cost and performance is the core of the cabling choice, copper still has more space in the access layer, optical modules are mainly used in long distance or high speed (10G or more) scenarios;

2) The number of optical modules under the traditional three-tier architecture is about 8.8 times the number of cabinets (8 40G, 0.8 100G);

3) The improved The number of optical modules under the three-tier architecture is about 9.2 times the number of cabinets (8 40G, 1.2 100G);
