The promotion of network bandwidth requirements by new applications such as online video and cloud computing has made China's optical communication chip market enter a high-speed growth period. Optical communication chips are developing in the direction of high bandwidth, small size, and low power consumption. High-bandwidth optical chip technologies supporting 100G are optimistic. However, China's optical communication chip industry has still not been able to get rid of the pattern of products focusing on low-end, small-scale enterprises, and high-end optical communication chips relying on foreign suppliers. Under such circumstances, the state and enterprises should take measures as soon as possible, through industry-university-research cooperation, technological breakthroughs, etc., to break through core technologies as soon as possible, improve product levels, and make them bigger and stronger.

New business drives growth of optical communication chip market

China vigorously promotes the construction of optical fiber networks, which will greatly promote the rapid growth of the optical communication chip market.

Online video, IPTV, cloud computing, P2P download, etc. are all new services that have emerged rapidly in the Internet field in recent years. While end users enjoy more and more high-speed video services, the demand for network bandwidth is also increasing. In response, Doron Tal, Director of Fiber Access Marketing of Broadcom ’s Broadband Communications Division, said that by 2015, global IP traffic will reach the order of zettabyte, and global broadband penetration will exceed one billion households. Optical communication access has enabled such intelligent services and a richer user experience through highly integrated, highly reliable, and cost-effective hardware and software solutions, and the market scale has expanded rapidly. According to data from InfoneTIcs, the number of new fiber access users will reach 35 million in 2012 and 50 million in 2016.

China market Due to the high investment in China's optical communication network, large construction scale, clear construction plan, and good government policy stimulus, there are currently many companies in the communications field, which has become an extremely attractive market space. In this regard, IDC analyst Shen Jianyong pointed out that China's vigorous promotion of information construction will greatly promote the development of the optical communications industry. With 3G networks, FTTx fiber access, smart grids, radio and television networks, triple play, "Broadband China", etc. With the implementation of a number of informatization projects, China's optical communications industry will experience explosive growth. For example, China Telecom plans to add 25 million fiber-to-the-home households in 2012, and 16 million new home users with fixed broadband access to the Internet. In the optical network construction plan, China Telecom plans to invest 40 billion yuan to engage in the construction of optical fiber infrastructure and accelerate the entry of optical fiber into households. The acceleration of optical communication network construction will inevitably drive the rapid growth of the optical communication chip market.

100G optical communication chip technology industry is optimistic

Currently 10G and 40G are being deployed around the world, and 100G has gradually been put on the agenda.

Under the optimistic market demand, optical communication chips have continuously shown new technological trends in recent years. For example, at the "2012 International Communications Exhibition" held recently, the reporter found that the technology of high-bandwidth optical communication chips supporting 100G is increasingly optimistic, and many network equipment manufacturers are talking about 100G technology. At present, 10G and 40G are being deployed around the world, playing an important role in the network, and 100G has gradually been put on the agenda. In this regard, Shen Jianyong pointed out that due to the increasing amount of data transmitted by the network, both the access network, the transmission network, and the backbone network are facing pressure on bandwidth. In the field of optical chips, high-bandwidth, especially technologies above 100G are widely optimistic. The speed-up of the access network bandwidth requires that the upper-layer aggregation layer network, the backbone layer, and the core layer network increase speed synchronously. The 10G-based optical transmission network will be rapidly upgraded along the roadmap of 40G and 100G. The mainstream manufacturers in the industry are accelerating the research and development of 100G equipment and devices. The maturity of 100G optical communication network products and technologies has entered a countdown.

In this case, chip companies have also continuously introduced related products. Recently, Broadcom launched the 100G Ethernet switching chip BCM88650, which is known as the world's highest density. The chip can realize high-density switching platform design, achieving up to 4000 100GbE ports. Its high degree of integration realizes the function of a complete line card on a chip. Broadcom stated that their BCM88650 chip is currently the only one on the market that supports 200Gbps single signal flow at layers 2 to 4, integrates 1G / 10G / 40G / 100GbE network interfaces, requires no additional components, and supports advanced packet signal classification, depth buffering, etc. Features. At the same time, Broadcom is also constantly introducing 10G chips that are still the current mainstream. For example, Broadcom recently announced in Beijing that it claims to have the industry's highest density of dual-, four-, and eight-port single-chip 10G-EPON optical line terminals (OLTs). The BCM5553x series of OLT system-level chips can increase the bandwidth by more than 10 times. Doron Tal said that operators now want to provide users with higher bandwidth, and operators can achieve higher revenue generation when providing higher bandwidth. In order to solve this problem for operators, the chips launched by Broadcom can provide corresponding services, such as "triple play" content services, high-definition, wireless backhaul, monitoring and business services, and cloud computing.

China's optical communication chips urgently need to break through to the high end

The domestic optical communications industry should focus on key technologies to form breakthroughs and change the current situation in which many of China's core chips rely on imports.

With the rapid growth of the optical communication market, China's optical communication system equipment companies and optical device manufacturers have increased their global status. However, chip products at the core of the technology are still highly dependent on imports as a whole. From the perspective of the competitive landscape of the optical communications industry, in recent years, cases of internal reorganization, merger and vertical integration of the international optical chip industry have continuously emerged, and the pattern between the big and the strong and the strong and strong among the enterprises has become more and more obvious. Merger and reorganization can help manufacturers broaden their product lines, and Broadcom completed the acquisition of BroadLight in April this year, further improving its end-to-end solution. For large equipment manufacturers, vertical integration can increase gross profit in a difficult price environment. Such as Huawei's acquisition of CIP and integration into devices; Cisco's acquisition of Lightwire is also continuously strengthening its strength in the core optical device field. This will form a new pressure for Chinese optical communication chip manufacturers.

In this regard, Shen Jianyong said that in the context of the European debt crisis, the growth rate of the communications market in developed countries is declining. Driven by the national strategy, the Chinese market still has growth potential and has formed a large market. This is both an opportunity and a challenge. There is an urgent need to promote Chinese enterprises to change the current dilemma of being large but not strong and not mastering core technologies. At present, a few Chinese companies have made breakthroughs in the chip field, but mainly low-end products. In the field of GPON chips, Huawei, ZTE and other equipment manufacturers have participated in the design of the chips themselves. For example, Huawei uses its HiSilicon chips. Some leading domestic optical device companies have also begun to expand upstream. Wuhan Optical Technology independently designed AWG chips based on PLC technology and began to make some breakthroughs in the chip field.

Optical communication chips are high-end communication technologies, with rapid technological development and fierce market competition. The domestic optical communication industry should focus on major applications and key technologies, form a series of technology alliances with enterprises as the mainstay, scientific research institutions and universities to participate in, actively explore new models for the successful industrialization of innovative technologies, and further improve China's optical communication field. Technical strength and world influence. The state should take measures to help enterprises to introduce core technical personnel, and enterprises should also take advantage of being close to the local market, combining the characteristics of first-, second-, and third-tier cities with different needs, increase investment in research and development, and conduct targeted development to change Not strong, many core chips rely on the status quo of imports.
