As the application of Internet of Things, VR/AR, high-definition video and so on promotes the high-speed growth of data flow, telecommunication network continues to upgrade, 5G pre-commercial deployment is imminent, China's optical communication industry shows good prospects for development, especially in the field of FTTH and base station, attracting the global major enterprises to scramble for layout. MITSUBISHI Electric is one of the optical communication module enterprises that are very optimistic about the Chinese market.
Recently, Mitsubishi Electric Semiconductor Asia Sales Director Kenji Fukuda told the Journal of Semiconductor Device Applications: "At present, China's telecommunications industry is developing rapidly, a variety of new services are also emerging, network consumption is rising. In addition, China's enterprises in the development of telecommunications equipment and production standards and specifications of the formulation of a growing sense of existence, can be said to be in the world's leading position in the telecommunications industry.

At the recent CIOE 2018 exhibition, Mitsubishi Motor brought 25 types of optical device products, and highlighted the new generation of high-power 10G EML TOCAN, commercial 25G DFB TOCAN, 25G EML TOCAN, 100G integrated EML TOSA, and the latest high-power 10G EML TOCAN and 25G EML TOCAN optical device products.
With the development of social networks and cloud computing, streaming media and video bandwidth is expanding. The emergence of mobile communication standards 5K and 4K, 8K images requires greater bandwidth and faster network speed. To this end, MITSUBISHI motor is very optimistic about FTTH, mobile phone base stations and data centers.
According to reports, in the field of fixed network, China surpassed Japan and South Korea to become the world's highest FTTH penetration country in 2017, access network transformation not only achieved stage results, but is upgraded to 10G PON. At the same time, the explosive growth of network traffic has brought enormous challenges to the carrying capacity of existing MAN, MAN ushered in a new round of upgrading process, and the sinking of 100G OTN has become a trend. At present, the operator 100G backbone network has been fully constructed, and gradually become a standard configuration, in the future will be further upgraded to 400G.
As China's PON market accounts for 80% of the global market, it should be the largest market, according to Mr. Honda. China's PON market has gradually upgraded from traditional E-PON and G-PON to 10G-EPON and XG-PON.
As the leader of FTTH devices, Mitsubishi Electric has met the huge demand for high-performance low-cost DLB APDs and 10G EML for GE-PON and G-PON, and is striving to meet the requirements of the future market to achieve high-power 10G EML to-CAN production by the end of this year, he said.
In addition, in the field of wireless networks, China's 5G technology research and development pilot phase III work has begun, operators 5G network pre-commercial deployment is imminent. As 5G will enable high-frequency communications, the use of micro base stations will increase significantly. According to the prediction, the base station deployment in 5G era will be more than twice of 4G, and the base station communication needs of mobile forward network and mobile return network need a large number of optical communication products.
Noda said that 5G verification experiments and development are now being carried out in various developed countries. It is expected that commercialization will be a relatively unified goal by 2020. China is the country with the largest market growth expectations.
He also said that the investment of 5G in China will reach 220 billion RMB in 2020 and 300 billion RMB in 2023. If the investment of other 5G related industries is included, it will reach 274 billion RMB in 2020 and 520 billion RMB in 2030. "We will continue to develop optical devices for different uses to achieve a win-win situation of high quality and reasonable prices, contributing to the expansion of 5G."
Mitsubishi Motor Optical Devices General Manager Sakashi Ho told Semiconductor Device Applications that 5G mobile base stations have more base stations than 4G LTE networks, especially mobile forward base stations.
Mitsubishi Motor has been pushing for the development of optical devices for 5G mobile base stations. The 5G communication speed requirement has greatly increased, so the optical communication network supporting it needs to exceed 25G. "It is not only the development of 25G BPS DFB, but also the unified development of product lines to meet the needs of the market and customers."
In addition, in the interview, MITSUBISHI motor focuses on several superior products.
According to the introduction, Mitsubishi Motor's new generation of high-power 10G EML TOCAN ML959A64/ML959D64 uses ring pin distribution to be easier to use and has higher chip output power; its own production capacity is superior to the existing 10G EML scheme ML958K55, aspheric lens type, flat window type of various schemes support different device design.
The commercial grade 25G DFB TOCAN ML764AA58T-96 is packaged with standard TO56 and can be used in Ethernet/CPRI 10km transmission. It supports 25.8/27.95 Gbps dual-rate through uncooled DML TOCAN and external chip drive. It is designed with a spherical lens and has a typical focal length of Df=6.6 mm.
25G EML TOCAN ML760B54 supports 25.8 Gbps rate, with a wavelength of 1270 nm and 1310 nm optional; output power of 0-5 dBm; extinction ratio of more than 6 dB at 1.0 V Vpp; operating temperature of - 20 ~95%.
100G integrated EML TOSA FU-402REA-1M5/FU-402REA-4M5 can be used for both 10km/40km transmission over 100G Ethernet and 400G CFP8 FR8/LR8 solutions. With 26.6G baud rate, it can be used for PAM4 modulation; low power, typical value 1.2W; LAN WDM technology, four-channel integrated devices; operating temperature range - 5 ~80 C; package size W6.7x L15 x H5.8mm.
