 5G Network Brings New Opportunity to Optical Communication Alerter l'administrateur Recommander à un ami Lien de l'article 

Since Ovum released its latest 5G subscriber forecast in December 2016, two major changes have taken place in the 5G market. First and foremost, in March of this year, 3GPP announced the acceleration of the development of some 5G standards to make it possible to standardize on commercial 5G deployments by 2019, one year ahead of the previous deployment schedule. In addition, with the acceleration of the 5G standard set-up, T-Mobile US, one of the major carriers, announced for the first time a nationwide 5G network deployment and the United States will be one of the largest in the world.

 

At present, 5G is in the crucial stage of the formation of technical standards. Major countries and operators in the world have started the 5G test in succession and successively issued strategic plans to carry out industrial layout and seize strategic high ground. China is also actively promoting the 5G technology research and industrialization, 5G technology research and development testing, international standardization support continue to make new progress. Recently, more than three major operators 5G infrastructure, total spending within seven years will reach 180 billion U.S. dollars heavy news came out, the 5G topic to an unprecedented peak.

 

As we all know, the future of 5G depends on small base stations. When the coverage of base stations is getting smaller and smaller, the number of base stations will increase exponentially. Taking the example of 3.5GHz, the number of base stations of 3.5GHz is more than the number of base stations of 800MHz and 1.8GHz Doubles. If it is planned more than 6GHz, the number of base stations will be more. If it is planned to 26GHz above, it does not know it will reach how many times. Therefore, a substantial increase in the number of base stations is an inevitable result, and the interconnection between base stations requires a lot of fiber. It is reported that at present, the number of base stations in China has reached more than 5 million, while the future development of 5G, conservative forecasts will reach 10 million or more, if the high-band, or even more.

 

Obviously, optical communication and 5G have met by chance. Accordingly, what is the impact of 5G on optical communications? The opportunities that 5G brings to optical communication are mainly including three parts: optical fibers, optical transceivers and optical network.

 

  1. First, optical fiber is the first beneficiary. 5G band is high and the number of base stations may be 2-3 times. If following the full coverage requirements, according to Fiber Broadband Association estimates, 5G fiber usage will be 16 times more than 4G. Consider China's 4G base station density is very high, the urban area only a few hundred meters spacing, it is estimated that the amount of 5G fiber is 4G 2-3 times.

 

  1. Second, optical transceiver module is the second beneficiary. Assuming that the 5G base station is 2-3 times as much as 4G, considering the medium / backhaul module, it is expected to bring tens of millions of 25GHz high-speed optical module usage. 5G flat architecture to the traditional huge capacity and cost pressures, which requires a large number of optical transceivers to support.

 

  1. Moreover, high-speed optical access network systems and optical devices are the third beneficiaries. The 5G architecture enables several decades of backhaul / midamble / preamble capacity up to tens of hundreds of Gbps levels and requires the introduction of 25G / 50G based CWDM or WDM for tunable lasers, tunable filters and CWDM / WDM devices High cost performance requirements; for TWDM PON systems, the demand for eCPRI and even edge ROADM systems is likely to increase significantly.

 

To sum up, we are currently at the pinnacle of opportunities and challenges in the 5G era. As the leading optical communications industry and optical component manufacturer in the 5G era, Gigalight has been closely following the market and moving ahead of 2016 in preparation for the beginning of 5G optical device product lines. At present, Gigalight owns a complete line of professional optical modules and other products. In particular, a large number of high-speed new products are launched in last year: 100G QSFP28 CWDM4, 100G QSFP28 PSM4, and 200G QSFP DD SR8.
