Does this mean that the future 400G optical modules will be based on QSFP-DD?
The optical modules modulation, there are internal modulation and external modulation.
The current data centers andtelecom operators are self-purchasing optical modules with field installation.
The Gigalight 200G/400G optical modules also have the advantage of low power consumption in the industry.
Master degree or above in optical communication, more than 8 years experience in overall architecture design of high-speed line-side optical modules;
Development of the test platform for optical modules and the entire process from testing to mass production;
At the beginning of this article,we mentioned that some optical transceiver manufacturers have also introduced 400G optical modules with OSFP and CFP8 form-factors.
The development of Gigalight's coherent optical modules is a groundbreaking of the Chinese optical module industry.
Time to enter 2019, when 400G has become a hot topic in the optical communications industry,the world's leading optical transceiver manufacturers have launched their own 400G optical modules.
Therefore, the dominant position of CFP series optical modules in telecommunication applications is at stake.
Moreover, the optical modules with fixed wavelengths and fixed lasers are more economical and reasonable in practical applications.
Currently, silicon optical module products mainly include short-distance data center optical modules andmedium-long-distance telecom coherent optical modules.
However, the coherent optical modules based on DSP processing technology of high-speed digital signal processing technology often encounter large power consumption problems.
However, the application of CWDM4 in the field of HPC is often stretched,because HPC data centers not only need optical modules to meet the requirements of large bandwidth, but also the characteristics of low delay and strict signal transmission….
Since the CFP series optical modules have been positioned for telecommunication applications, and the port density requirements are not as high as in the data center, so the size is acceptable.
Gigalight began to offer 25G/100G optical modules and active optical cables to customers worldwide.
The arguers said that, sending optical modules with different wavelengths to the construction field is more likely to make mistakes than sending a batch of identical optical modules to the construction field at least.
There is no difference between using optical modules with the same label and using optical modules with clear label wavelengths.
The coherent optical modules are used for DCI connection in data centers or telecom metropolitan area backbone network long-distance communication, coherent modulation adds phase modulation in addition to amplitude modulation compared to traditional MZI external modulation.
In addition, the Gigalight 40G QSFP+ ER4 optical modules support customized requirements and are able to respond to and deliver high volume production requirements in a timely manner.
For CFP andCFP2 series optical modules, the CFP to QSFP28 adapter and CFP2 to QSFP28 adapter have been available for a long time, indicating that some users have switched to QSFP28 optical modules. .
However, with the advancement of technology,the QSFP series optical modules are also beginning to be suitable for telecommunication applications, and the power consumption of QSFP series optical modules is much lower than that of CFP series optical modules.
Since the production of high-speed 100G/200G/400G optical modules must rely on high-precision and high-efficiency automation equipments, and the purchase of an automated production line requires huge costs, Gigalight has independently developed key automated production equipment since July last year.
When we list the form-factors of these manufacturers' 400G optical modules(as shown in the figure below), we found that all the manufacturers except the Finisar(acquired by II-VI)have adopted the QSFP-DD form-factor- the market seems to have recognized QSFP-DD as the first choice for form-factors of 400G optical modules, though some manufacturers have also introduced 400G optical modules with OSFP and CFP8 form-factors.
You know, after long-term training, all the optical module manufacturers pursue the principle of zero-error quality.
This is a fallacy of weakening the capability of optical module manufacturers.
The silicon waveguide is an important passive structure in the silicon optical module.
In the data center optical module market, due to the large demand within 2km, coupled with the strong requirements of low cost, high speed, high density, etc.
Due to the ideal working environment of constant temperature andhumidity in the data center, optical module packaging requirements are relatively low.
Matching with the transmitting end, the optical module also needs a receiving detector that receives the optical signal.
