With the high speed development of the Networks, optical modules have a more and more important functions in the data center.
But what the challenges will the data center bring for the modules?
How do the optical transceivers modules change to face all?
Today, let us discuss about it.
Challenges may bring for the modules:
1. Higher Cost of the Optical Modules:
Because of the very higher and large cost for the data center,
Higher requirements of the optical modules for the data center demand that the cost must be controlled.
So Lower cost modules is very important now.
At present, though for different customers or different rates of modules, the market price of modules is still five or ten times higher than the ideal "low price".
If just do the changes for the design or production methods, it is very difficult to reduce the cost.
New standard agreements need to be made for the Network market to fit the requirements of the lower cost not only the suppliers but also the users.
2. Transition from 40G to 100G optical modules for the data center:
Now most large data centers usually use 10G access ports to access 40G switching networks.
However, 25G access ports and 100G switching networks will be rapidly advancing in the next few years.
In the data center, the shape specification is an important factor that determines the application of optical modules.
SFP+ modules are widely used in 10G access ports for the reasons of its high performance and cost savings.
But SFP+ will be not so long, because when the access speed increases to 25G, 10G, the access port will transition to SFP28.
QSFP28 transceiver is a new trend of 100G applications.
3. Considering Factors of Over-100G for the data center:
Now, all the optical field are discussing for the over-100G modules,
The next-generation of 40G and 100G will be 4X series, such as 200G/400G for the data center.
Optical modules also need to grow to over-100G to meet these needs.
One of the most important values for measuring data center switches is the front panel bandwidth.
That is, all optical modules need to adapt to the aggregation bandwidth of a wide 19 ", high 1RU switching device.
Development of the optical modules:
As a key factor for the data center, optical modules have a very bright and longer.
Solutions for 40G to connect the 100G is a trend, and at that time, the standard of over-100G must be made urgently.
New optical modules must be necessary for all.
We all believe that there will be more new type or new connector optical modules program in the development of future.
Also optical modules will be more and more suitable for the data center in the future.
