6 Yue 12 Ri ~ 13 days, the two-day 2019 China Optical Network seminar held in Beijing. Representatives from research institutions, telecom operators, Internet service providers, data centers, industry alliances, and equipment and technology providers attended. On the afternoon of the 13th , Dai Qiwei, deputy manager of the terminal access product line of Guangxun Technology Access Products Business Unit, and Dr. Zhang Bo, Photovoltaic Technology R&D Department, were invited to participate in the 2019 China Optical Network Seminar and delivered a keynote speech, which was consistent with experts and scholars on site. Praise.

   High-speed PON products can effectively reduce costs based on massive demand with self-made optical chips

  At the UWB Access and Business Development Forum, Dai Qiwei gave a keynote speech entitled "Application Prospects and Challenges of High-Speed PON Optical Modules".

The next-generation PON product update iteration speed is expected to accelerate. At present, the globalPON market is growing steadily. The Chinese market share has declined slightly in 2018 , but it is still the most important PON market. In the market application, 2.5G GPON OLT/ONU will remain the most important product in the global PON market in the next three years . The new 10G GPON OLT/ONU will usher in a rapid time window with a compound annual growth rate of 50%. the above.

Dai Qiwei said that the competition in the future 10G PON market will be fierce. In particular, each device supplier must not only master high-end product technology, but also have superior low-cost manufacturing and flexible delivery capabilities to meet customer development needs. To this end, Guangxun Technology will give full play to its comprehensive and systematic industrial comprehensive advantages, actively promote the development of a new generation of PON products, and help the rapid development of the new generation of PON .

  The cost and mass production advantages of silicon light offer the possibility of coherent sinking based on silicon light platforms

In the special forum on the development and application of silicon-based photonics integration technology, Dr. Zhang Bo gave a keynote speech on "Application of Silicon Light Technology in Coherent Optical Modules" to answer the hot issues of common concern in the industry.

As the integration of chips and packages increases, what era will coherent optical devices enter? At present, the pluggable optical module has been developed to the CFP2-DCO phase, and will enter the QSFP-DD-DCO phase immediately . The panel density of the 1U veneer will also reach the upper limit. In order to further enhance the density of the board, lower power consumption, the rear plate toward the coherent light module light ( OBO ) or block bonded seal ( CO- P ackaging development form). Meanwhile, the coherent optical device will enter a discrete devices 2in1 even 3in1 multiple device integration times, to better meet the coherent light module to lower power consumption, smaller size and lower cost requirements. In addition, as the integration of chips and packages is further increased, the boundaries between modules, devices, and chips will become increasingly blurred.

What are the advantages and disadvantages of silicon light technology in coherent products? Silicon light technology exerts its own platform advantages and is widely used in coherent optical products, such as high production capacity, low cost, small size, high integration, and also has its own defects, such as the lack of light source and the disadvantage of coherent modulator performance. This allows the silicon light and indium phosphide platform to coexist for a long time in the coherent optical module product. Both platforms have their own advantages for different application scenarios.

The cost and mass production advantages of silicon light bring the possibility of coherent sinking based on silicon light platform. In the 400G era, the gray light coherence scheme can replace the EML combining scheme and sink to the application scene of 10km . In the 800G era, the gray-light coherence scheme may replace the silicon-light DR8 scheme and sink to 500m-2km .

Through continuous technical accumulation and perfect independent innovation system, Guangxun Technology has made certain contributions to the field of optoelectronic devices. The company's products sell well both at home and abroad, and provide more than 40 mainstream communication manufacturers in more than 20 countries and regions around the world. Innovative technology applications and reliable solutions. The company cooperated with the National Optoelectronics Innovation Center and successfully launched an integrated coherent light-emitting component based on a silicon light platform in 2018. In the future ,Guangxun Technology will promote the development of coherent optical communication technology based on its years of packaging capabilities and platform advantages , and promote its application in more communication fields, providing customers with more valuable products and services, and opening up the information society. A beautiful tomorrow.
