The development of optical fiber access networks is very rapid and has been widely used in various fields. The advantages and disadvantages of optical fiber access networks and ADSL access are analyzed in detail below. The rapid development of the Internet has led to the further prosperity of the Internet bar industry. The access methods of Internet cafes are also different, and network networking solutions

Along with the social progress and development, as well as people's growing material and cultural needs, communication to large capacity, long-distance direction of development has been an inevitable trend of development. Since the light wave has a very high frequency (about 300 million MHz), that is, it has a very high bandwidth to accommodate huge communication information, so the use of optical waves as a carrier for communication has been the goal of people for more than hundreds of years to

1. FTTH development at home and abroad The narrow-sense FTTH cable refers to the further extension of fiber to the user side, ITU believes that FTTH from the fiber-optic end of the photoelectric converter to the user no more than 200 meters, thereby eliminating the need to install an electronic access system in the metal, but not excluding photoelectric converters and desktop terminals using unlimited syst

The dual-fiber access router is the most suitable access method for Internet cafes. So I studied the specific solution of the dual-fiber access router in Internet cafes. I will share it with you here, hoping it will be useful to you. In recent years, Internet cafes have become more and more formal and scaled, and the demand for network bandwidth is also growing. Due to the slow data transmission rate provid

In recent years, with the explosive growth of IP business volume, China Telecom is beginning to develop towards the next generation of Sustainable Development. Building a fiber-optic infrastructure with huge transmission capacity is the physical basis of the next generation of networks. The traditional G.652 single-mode optical fiber has been unable to meet the above-mentioned development needs of ultra-hig

Optical Fiber Laser principles and characteristics I. Introduction Fiber Laser (Fiber Laser) is a device that uses glass Fiber reinforced with rare earth elements as the gain medium to produce Laser output. The fiber laser can be developed based on the

Optical fiber In the erection, after the completion of the weld test work, the use of the instrument is mainly OTDR tester, with the Canadian EXFO ftb-100b portable Chinese color touch screen OTDR tester (Dynamic range of 32/31, 37.5/35, 40/38, 45/43db), you can test, The position of optical fiber breakpoint, the whole loss of optical fiber link, the loss distrib

system. They can be achieved through coaxial cable, optical cable, wireless or microwave. The video transmission system is the system's image signal path. A sound video transmission design is a very important part of the video monitoring system. If a well-built system selects cameras, lenses, monitors, and video recorders that can produce or process high-quality images, but does not have a good transmission system, eventually, the images seen on the monitor will not be satisfactory. According t

MPO/MTP high-density optical fiber pre-connection system is mainly used in three fields: application of high-density environment in data centers, application of optical fiber to building, application of optical fiber to optical splitter, 40G, 100g sfp, connection applications of SFP + and other optical transceiver devices. This article focuses on why MPO/MTP high

Because the network monitors the long-distance widespread need to use the optical fiber equipment, considers the customer to have the understanding optical fiber connection method The need, therefore below will briefly introduce the fiber optic cable, the terminal box, the tail fiber function and the connection methodT

The following describes FTTH access technical standards and deployment solutions, including how FTTH is connected to your network. As copper prices keep rising and the cost of optical cables keep decreasing, fiber-to-household (FTTH) services that provide bandwidth much higher than metal wire access are becoming the focus of ISP (broadband operator) promotion this year, in the near future, high-speed broadband will no longer be a dream for ordinary co

In the past two years, with the development of the communication industry and the implementation of national policies, China's FTTH has developed rapidly from the pilot project to the current scale deployment. As an important part of FTTH construction, fiber connection doubles the engineering volume. Meanwhile, the extension of FTTH construction connection point to the indoor environment also brings about a significant increase in the difficulty of wo
