The main technical trends of optical fiber communication
In the field of optical communication, different companies hold different opinions about the trends of industrial SFP transceivers. But we would like to talk about our ideas today to share with you all.
The main trends of current optical products including:
A miniaturization and integration;
B miniaturization and lower cost;
C higher speed and larger capacity;
D lower power consumption;
E closed proprietary to open and flexible.
Smaller, more integrated, lower cost, lower power consumption, greater capacity, in fact, is the development trend of optical communication products. And the last one(E) to open and flexible, is the new trend of SDN technology, but also the most important trend.
Miniaturization, integration, low cost, high speed, large capacity and low power consumption, all these have been the requirements of optical communication products in different times. But they present different details in different times even they always combine each together. In 2016, the ultra small PD of German Karlsruhe Institute, TE micro qsfp28 modules, qsfp28 modules DD and other MSA are on behalf of the development of this miniaturization technology. In the aspect of the integration technology, silicon photonic is very hot this year, but not the only option. In fact, integration is not only the integration of the chip level, the current integration of active devices and passive devices is also a kind of integration. There are very few individual passive or active devices.
Optical communications manufacturers have been committed to reducing costs and power consumption. The emergence of the ACO CFP module is a cost reduction effort. COBO alliance’s goal is to reduce cost, but also to reduce power consumption. The emergence of the technology is directly related to the needs of the system vendors. Ignoring the impact of these trends, today's dominant manufacturers may fall behind. These technological changes are more important for China's optical communications companies, because these technologies may be more likely to change the package. After all, to make progress like Ranovus in the quantum dot chip is not easy for Chinese manufacturers.
High speed and large capacity is always the goal of optical communication companies. Current hot spots in this area are related to modulation techniques and optical fibers in the 400Gbps and more high speed systems. Compared to the pursuit on the 400Gbps and the experiment, China's optical communication companies should pay more attention to the 25Gbps system. Regardless of Ethernet, PON or 5G mobile communications, 25Gbps will become an important rate in the near future.
From the closed proprietary OEM network equipment to steering flexible reconfigurable open platform is the most important trend in optical communication technology this year since OFC. TIP of Facebook shows ADVA and other equipment companies will support open source optical network equipment plan. From closed to open is the trend of the Internet era, and optical communication will not be forever excluded. How to make our products more flexible and how to support open source, these should be the important issues in the next two years of us all.
