News on September 7 Optical communication and wireless have never been insulators, but a pair of mutually successful CPs. In the 4G LTE era, the construction of base stations has brought about the demand for optical interconnection of submarine cables. The surge in traffic has forced transmission and backbone network upgrades, bringing historical development opportunities to optical communication manufacturers such as Hengtong Optoelectronics, and Hengtong Optoelectronics has also been singing all the way. , To become one of the largest optical fiber and cable suppliers in China and even in the world.
The wireless industry is about to enter the 5G era. At the 20th China Optical Expo that opened recently, 5G has also become a hot topic. The booth of Hengtong Optoelectronics, from silicon photonics to data centers, 5G, and the Internet of Things, all showed the integration of optical communications and 5G, depicting future application scenarios. At the booth, Dr. Shi Huiping, 5G chief engineer of Hengtong Optoelectronics, was interviewed by reporters and talked about Hengtong Optoelectronics' ambitions in the 5G field.
It is well known in the industry that the frequency band deployed for 5G is higher. Although the bandwidth is larger, the base station coverage radius is relatively small, and more base stations need to be deployed. The interconnection and transmission between these base stations will inevitably bring about the demand for optical fiber. Industry authoritative expert Wei Leping pointed out that 5G competition is evolving into competition for optical fiber infrastructure.
"5G bearer takes the lead and cannot be separated from the most basic media media fiber optic cable. Optical fiber can be said to be irreplaceable." Dr. Shi Huiping believes that the commercial development of 5G will only push the fiber optic cable industry to a higher level rather than suppress it. In the future, new industrial development and application demands will continue to emerge. This is an important opportunity for Hengtong Optoelectronics to continue to strengthen its main cable business.
5G not only brings demand, but also demands. Compared with the previous generation of technology, 5G faces the three major business scenarios of large bandwidth, high reliability, and low latency, and requires the support of the technological evolution of the entire industry chain. From the perspective of optical fiber and cable, ultra-low loss optical fiber needs to be deployed in long-distance backbone networks. Hengtong Optoelectronics' G.654E ultra-low loss optical fiber is the only one selected for the 2016 “Ultra Low Loss Optical Fiber†project of the industrial strong foundation project, aiming at 5G belt The coming backbone network is upgraded.
Second, in the bearer and access network, with the rapid growth of traffic brought by 5G, high-density fiber optic connection solutions are required, and data center convergence also requires high-density connections. Furthermore, with the widespread deployment of 5G base stations, Hengtong has launched a large number of long-distance optical cables to meet the needs of large bandwidths such as 25G.
"Our 5G relies on various product lines, involving 5G-related products, which have been upgraded to a strategic height, and R&D resources are ranked the highest. In the long run, 5G will bring a positive impetus, and it will come faster than imagined. We must practice our internal strength well." Dr. Shi Huiping said.
100G silicon optical module made a stunning appearanceAt this optical expo, Hengtong’s booth not only had the iconic super-size optical fiber preforms, but also exhibited silicon photonic modules, marine optical fiber cable systems and other products, which attracted close attention from the industry. ???????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????
Among them, the 100G finished silicon optical module shines in Hall 1 alone. The commercialization of silicon photonics technology has always been the industry's expectation. However, the high attenuation and high temperature cracking characteristics of silicon photonics optical device chip links have always been a stumbling block to large-scale commercialization. In 2017, Hengtong Group invested heavily in joint research projects with outstanding domestic and foreign R&D teams, and recently achieved important breakthroughs in the project: China took the lead in completing the first trial production and reliability testing of 100Gbps silicon optical chips, as well as the construction of a silicon photonic chip test platform. .
Dr. Shi Huiping said that Hengtong Optoelectronics is positioned at a very high starting point to cut into silicon optical modules, which has attracted the attention of operators, data users and the media, and is the most popular product in the entire booth. It is expected that applications will be launched in the market next year. Compared with traditional optical modules, it has obvious cost advantages and can meet the large-scale application needs of low-cost, low-power, high-speed, and high-bandwidth optical modules in data centers and 5G wireless communications.
In addition, Hengtong's marine optical cable system and other products are also worth mentioning. As one of the earliest manufacturers in China to enter the submarine cable market, Hengtong Optoelectronics has become the largest submarine cable system supplier in China. It has not only moved from offshore to deep sea, but has also "landed" for monitoring, breeding and pollution control of rivers and lakes. In the future, 5G In the era of large-scale commercial use, Hengtong Optoelectronics' underwater technology and big data accumulation will also be a big boost for industry applications.
5G is not only a communication technology, but also has great potential in applications other than communication. It is also the core foundation of the information industry that the national strategy attaches importance to. From the exhibition and interviews, we can see that Hengtong Optoelectronics attaches great importance to 5G and has accumulated in product applications, preparing for 5G commercial use, and fully demonstrating its value in the 5G era.
