Communication cable filling paste manufacturers talk about optical fiber will enter a new field

At present, the average coverage rate of broadband network in China is less than 10%, which has not reached the level of 30% ~ 40% in capitalist countries. The announcement of broadband network development strategy is very necessary and immediate. In recent years, with the announcement of broadband deployment of optical fiber network in China, the coverage and connection speed of wireless network have been significantly enhanced. However, compared with capitalist countries, there are still great differences in China's technical independent innovation ability of optical fiber connection and broadband coverage of optical fiber network, especially the technical, standard and application level of optical fiber final 100m connection need to be further improved. Communication cable filling paste manufacturers believe that with the advent of new optical fiber technology and the promotion of new national policies, China's optical fiber transmission has entered a new development trend industry and promoted the deep-seated development trend of intelligent security transmission industrial chain.

Application of new optical fiber technology

According to the relevant news media, the scientific research staff of the University of Southampton in the United States have made a new optical waveguide, which can transmit data at the speed of 99.7% light. Using this new type of optical guide, scientific research staff completed the data and information transmission rate of 73.7 TBPs - about the same as 10 TBPs, 1000 times faster than today's 49 GB optical guide, and the delay time rate was greatly reduced.

It is understood that the speed of light in the vacuum pump is 299792458 M / s, but the rapid propagation in other substances is generally much slower. In the basic light guide made of quartz glass tube, the speed of light will be reduced by 31%. In fact, the transmission rate of light in the air is faster than that of laminated glass, which is why the scientific research staff of the University of Southampton applied a hollow light guide that is basically completely filled with gas to carry out transmission.

According to the completely improved hollow design scheme, the scientific research staff got rid of this problem and applied a photonic band gap edge. This kind of new design scheme can complete the lossless (3.5db / km), broadband network width (160nm) and its delay time rate much better than the basic optical waveguide, so as to improve the transmission rate of light source and data information by 31%.

Smart home industry welcomes development trends and opportunities

According to the news media, the Ministry of housing and urban rural development and the Ministry of industrial production and information management have jointly issued a circular stipulating the implementation of the national industry standard of fiber to home. Communication cable filling paste manufacturers believe that the circular stipulates the full implementation of fiber to home in newly created residential buildings. According to the provisions of the national industry standard for optical fiber to the home, since April 1, 2013, in the counties, cities and above urban areas where the public China mobile broadband has completed optical fiber transmission, the communication equipment of newly established residential communities and residential buildings shall use the basic construction of optical fiber to the home method, and at the same time, encourage and apply the standard cities and towns Newly built residential areas and residential buildings in rural areas have completed fiber to home.
