Fiber optic cable competition continues to heat up

With the popularity of the Internet, the demand for communication bandwidth in society is increasing. In order to be able to transmit more data, the use of optical fiber communications is undoubtedly a good choice. Recently, scientists successfully developed a new type of optical fiber that can achieve a data transfer rate of 255TB per second, which is 21 times more efficient than the current commercial fiber.

Unlike a typical commercial fiber, which has only one core available for transmission, this new type of fiber has seven different cores. This is like converting a one-lane road into a seven-lane road. At the same time, the researchers also introduced two additional vertical channels for data transmission in this fiber. Through the comprehensive application of these two methods, the efficiency of optical fiber transmission has been effectively improved. The emergence of this technology will make it possible to achieve PT-level transmission efficiency, which will greatly ease the crisis caused by tight bandwidth resources.

In 2009, China issued 3G licenses and China set off a new round of network construction. China's fiber optic cable manufacturers have risen rapidly after years of silence, and both production and sales have seen growth of several times. By 2013, domestic fiber optic cables have accounted for more than 70% of the market share, and the overall annual production capacity has reached 250 million core kilometers, which can meet the needs of the world. . The market demand stimulated a serious surplus of production capacity, leading domestic fiber optic cable manufacturers to face severe production capacity digestion crisis.

In this great leap forward, small-sized optical fiber cable plants were gradually phased out and their market share was rapidly concentrated. The leading manufacturers were all formed the optical-fiber-fiber-optic cable full-industry chain competitive advantage, and also extended their advantages to ODN. China Mobile’s recently concluded largest collection of fiber optic cables has reduced the list of successful bidders. According to industry sources, China Telecom and China Unicom will follow suit, which will further exacerbate the concentration of the optical fiber and cable market.

Fiber optic cable manufacturers have expanded their ODN market downstream and started to compete with traditional ODN vendors. This is another new topic. The optical fiber and cable industry chain itself has formed a highly competitive development trend in the entire industry chain. The main competition between manufacturers is the scale economy and cost control capabilities. Coupled with the market demand will not decline in the next few years, leading to the expansion of optical fiber production capacity is unstoppable. Excessive capacity, if not digested, is bound to trigger vicious competition in the industry.

New market opportunities have eased this situation. Since 2012, China's optical fiber and cable manufacturers have adopted a "go global" strategy and have absorbed excess capacity through the international market. The most radical implementation of this strategy is Hengtong Optoelectronics. The “555 internationalization strategy” proposed by the company will have more than 50% of the international market, more than 50% of international capital, and more than 50% of international talent in the coming years. . At the time of the bubble crisis in 2000, Chinese manufacturers with excess capacity did not have the strength to go out and get trapped in the domestic market. With the advancement of technology, Chinese manufacturers have the strength to expand the international market in the next decade, compete with foreign companies on the same platform, and obtain greater results. The development of space.

In recent years, because of the rapid development of optical fiber communication technologies, the cost of high-definition transmission monitoring systems for high-definition optical transmission networks has also been drastically reduced. Therefore, the use of optical fibers and optical transceivers in high-definition transmission monitoring systems has become more and more widespread. Optical fiber has been widely used in home optical fibers and unit access networks in the areas of home intelligence, office automation, industrial control network high-definition transmitters, automotive airborne and military communications networks. With respect to high-definition video signal superimposer streams that require high-definition network transmission bandwidth and high-definition network transmission intervals, it is no longer a dream to complete high-definition HD transmission monitoring.

According to the statistics of the Ministry of Industry and Information Technology, from January to June 2014, the nationwide new optical cable line was 1.386 million kilometers, and the total length of the optical cable line was 18.838 million kilometers, a year-on-year increase of 18.1%. The 4G network promoted the high-speed development of the optical fiber and cable industry.

Our Battery Smart Monitoring system is direct integration of the battery restore solution into computer-based battery monitoring system which combines wireless communication with patented, field-proven battery monitor and analysis technology. It not only has the ability to restore battery, but also has the ability to monitor battery's State-Of- Health(SOH) in real time. It is much more intelligent than Smart Pulse Protector and Pulse Restore System because of it's battery remote management and maintenance function with wireless communication.  
It is comprised of 3 base hardware which consists of a monitoring host, several monitoring modules, and several data box modules. Plus 1 software operation system. The monitor parts connected wirelessly with batteries pack and reliably reports battery State-Of-Health(SOH) to the software platform.  
The battery monitoring system adopts a inspection module for each battery analysis and monitoring. Through the wireless communication technology, every single battery's SOH data collected by monitor is concentrated into the data box module. The data box module is used to collect the battery's voltage, temperature, internal resistance and current simultaneously. Then transmit all the data to the monitoring host which can do data displaying, analysis, storage, and alarming as soon as abnormal. Battery Monitoring System
Since the Monitoring system is integrated with Base Site Battery Protector System, The real-time improvement of the battery equalization and small pulse current desulfation, lead to the battery lifespan prolonged up to 2 times. Meanwhile, monitor battery's State-Of- Health(SOH) and State-Of-Charge (SOC) in real time to make sure keeping the back up power system always safe and uptime.
