Data Center Solutions

The data center interconnection infrastructure is mainly composed of switches and servers, and also uses optical cables and optical transceivers, or active optical cables and direct cables for connection. In the data center, the explosive growth of traffic is promoting the upgrade and acceleration of the data rate of optical modules. It may only take 10 years to go from 10G to 400G, especially the rising internal and export traffic of AI, VR/AR, UHD video, etc. The flat data center architecture makes the 100G optical module market continue to grow at a high speed.

 


 

The direction of the main data flow of traditional 3-tier data center is from top to bottom or from south to north, while the direction of the main data flow of flat spine-leaf data center is from east to west.

Here is a data center optical interconnect application case of optical transceivers and AOC. The network architecture of a Cloud Data Center is pided into Spine Core, Edge Core, and ToR (Top of Rack). The 10G SFP+ AOC is used for the interconnection between the ToR access switches and the server NICs. The 40G QSFP+ SR4 optical transceivers and MTP/MPO cables are used for the interconnection between the ToR access switches and the Edge Core switches. The 100G QSFP28 CWDM4 optical transceivers and duplex LC cables are used for the interconnection between the Edge Core switches and the Spine Core switches.


 

According to the difference in the rate of increase in flow, network architecture, reliability requirements and the environment of the machine room compared to telecommunication networks, the demand for optical transceivers of cloud data centers has the following characteristics: shorter iteration period, higher speed, higher density, lower power consumption and use by mass.


KEY FEATURES:

Shorter iteration period

The rapid growth of data center traffic is driving the upgrading of optical transceivers in acceleration. The iteration period of data center hardware devices including optical transceivers is about 3 years, while the iterative period of telecommunication optical transceivers is usually over 6-7 years.
 

Higher speed

Because of the explosive growth of data center traffic, the technology iteration of optical transceivers can not catch up with the demand, and almost all the most advanced technologies are applied to data centers. For higher speed optical transceivers, there is always a demand for data centers, and the key question is whether the technology is mature or not.
 

Higher density

The high density core is to improve the transmission capacity of the switches and the single boards of the servers, in essence, to meet the demand of high speed increasing flow. At the same time, the higher the density is, the less switches are needed be deployed, and the resources of the machine room can be saved.
 

Lower power consumption

The power consumption of the data center is very large. Lower power consumption is to save energy and ensure better heat dissipation. Because there are full of optical transceivers on the backboards of the data centers, if the heat dissipation problem can not be properly solved, the performance and density of the optical transceivers will be affected.
