On November 29, the 2013 optical fiber communication development report was held in Panyu, Guangzhou, and the reporters were invited to participate in the conference and had the honor to listen to the wonderful speeches
of all academicians.
Taking advantage of the tea break, the reporter interviewed Jian Shuisheng
, an academician of the Chinese Academy of Sciences.
Academician Jian said that he is not optimistic about plastic optical fiber, first of all, the price of foreign quartz optical fiber has dropped to about 40 yuan, while domestic plastic optical fiber is still 600 to 700 yuan; Secondly, in terms of temperature stability, plastic optical fiber has high temperature resistance and performance is not competitive; More seriously, the loss of plastic optical fiber is large, the loss of quartz optical fiber is only 0.
18db/km, while the loss of plastic optical fiber is 0.
5db/km, and the loss of plastic optical fiber per kilometer is too large

.
Academician Jian also mentioned in the report that the current network can save more than 99% of energy by changing to optical exchange, and it is urgent to study optical exchange, and put forward a vision, hoping that T-level capacity switches will be realized
first in China.
first in China.
Wu Hequan, an academician of the Chinese Academy of Engineering, mentioned in the report the establishment of large-scale data centers, and with the flattening of mobile networks, the demand for optical splitters will rise
in the future.
Academician Wu also emphasized that the former domestic large data center has strict requirements for the environment and climate, previously built in the southeast and other places of data center, with the "data center cloudification", the future will be built in the west of Ningxia, Hohhot, Guiyang and other places, the subsequent layout may not be centralized may be decentralized layout, then the connection between data centers requires a large number of optical fiber cables, which will also bring growth opportunities
to the entire optical communication.

to the entire optical communication.
In addition, Academician Wu also mentioned that with the advent of the era of big data, a server can no longer hold a large amount of data, then in the future, the exchange between servers will be more, becoming a C to C cloud, and the server will also be marginalized, which will bring new growth points
.
The decentralization of the global Internet, the OTT of network pipelines, and the intelligent management of service management will bring opportunities
to the development of optical communications.
At present, the popularity of WIFI will also drive the construction of base stations, and the diversification of mobile communication will also bring opportunities for optical communications, such as small cell systems launched
.
"Some people think that wireless is stealing the wired business, but it also provides opportunities.
"
With the flattening of mobile networks and the strengthening of China's Internet interconnection architecture, configurable optical plug-and-drop ROADMs will be used more and more, although the current usage is not large

.
Mao Qian, senior consultant of Wuhan Research Institute of Posts and Telecommunications, mentioned in the report that the all-optical network has encountered two major technical problems - optical storage and optical logic devices, and optical storage is relatively difficult to cross
.
.
Zhu Ninghua, deputy director of the Institute of Semiconductor R&D of the Chinese Academy of Sciences, introduced the report "Research Status and Trend of Optoelectronic Devices Supporting the Development of Optical Networks", pointing out four trends in the future development of optoelectronics: first, optoelectronic integration, second, the integration of microelectronics and optoelectronics, third, silicon-based optoelectronic integration technology, and fourth, multi-dimensional modulation and multiplexing
.
It is emphasized that the development trend of optoelectronics in the future will develop from unit devices to integrated chips, of which 40Gb/s will become the core of optical access, and it is also proposed that TWDM-PON will be the mainstream technology for future development, and the research and development of high-speed lasers will also become the focus

Dr.
Tang Xiongyan of China Unicom Research Institute mentioned the concept of "intelligent pan", and the reporter discussed with Dr.
Tang and learned that the FTTH fixed network cannot be as fierce as in previous years, and it will be stable after that, but wireless cannot be completely replaced
.
In addition, the reporter also exchanged some views on the splitter market with Dr.
Tang, who said that the current situation is indeed not optimistic, price competition is fierce, the survival of enterprises is difficult, and the products are uneven
.
It is true that operators have also formulated some standards for splitters, but due to the impact of bidding prices, the actual specifications have not been implemented, and Mr.
Tang also expects that the market
can be maintained through joint efforts of upstream and downstream.

In addition, on the device manufacturers concerned about the PON market trend, the reporter also communicated with Dr.
Tang, Dr.
Tang said that operators also understand the current market competition of PON, but from China Unicom data can be seen that ARPU has not grown, most of the revenue comes from 3G driven, so at the operator level is also very cautious about investment, so it is also very sensitive
to price.
According to Dr.
Tang, many PON manufacturers are counting on ONU to make money, but the subsequent OLT and ONU will be tendered separately, which means that the competition between the two product markets will be more intense, which has sounded the alarm for our optical device manufacturers

The most impressive thing for the reporter is the report of Dr.
Zhou Liang of the R&D Department of Guangxun Technology, therefore, the reporter also interviewed Dr.
Zhou at the table, asked about the progress of 40G and 100G research and development, Dr.
Zhou said that 40G products have been sent samples, the technology used by the company is different from other homes, and the transmission distance does not need to replace the module, which can prepare for future mass production and cost reduction, and is currently in active R&D testing, and it is expected that samples can be launched early next year
