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

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

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

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

From the perspective of Internet cafe performance, the optical fiber access and ADSL access technologies are worth learning. Here we mainly introduce the use of optical fiber access and ADSL Access to PC shared Internet, this section describes some knowledge points, such as DHCP, security, and TCP/IP network protocols. The rapid development of the Internet has led to the further prosperity of the Internet b

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

soon be realized by seven kinds of wiring system, at present the US Corning Company's seven kind of wiring system has already been leading the industry to reach the 1200MHz bandwidth. Compared to fiber-optic LANs, the seven-class system offers the desired performance and bandwidth, but its overall cost is only one of a fraction of the fiber. Some people think that fib
