The installation of protocol-based (such as Gigabit Ethernet) networks boosts the rapid increase in the use of optical cables in Lan, which can meet the increasing bandwidth and transmission speed requirements. Multi-mode optical fiber cables are especially used for Gigabit Networks) and single-mode optical fiber cables are widely used in buildings as high-speed transmission media. Therefore, in order to ge

Brief history of Optical Fibers As early as 1841, Daniel Colladon of Switzerland first elaborated on the idea of transmitting a beam through a water jet. Then, through a beam in the water flow across the table, he realized light propagation in the water flow through total reflection, and created the original idea of transmitting information through optical transmission. In 1880, engineer William Wheeler lights the entire room through a series of glass tubes. In 1965, Charles Kao and George Hockh

1 Development of Optical Fiber Communication In 1966, the Chinese Scholar Gao was a Chinese scholar. k. KA) and hawkhaamu C. k. HOCKHAM) published a paper on the new concept of transmission media, pointed out the possibility and technical path of using optical fiber OpticalFiber for information transmission, and laid the foundation for modern optical communication-optical

A Broadband Router is one of the most commonly used routes and has a large market demand. Here we will mainly explain that FTTH is the best choice for fiber-optic direct access to the home, including the current broadband routers that can perfectly support FTTH access solutions. As copper prices keep rising and the cost of optical cables keep decreasing, fiber-to-household (FTTH) services that provide bandw

The continuation of optical fiber (1) Fiber continuity. Optical fiber connection should be followed by the principle: when the core number is equal, to the same beam tube of the corresponding color optical fiber docking, the core number is not at the same time, in order to connect the core number of large, and then th

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

Introduction to Optical Fiber Temperature Measurement Technology in data centers The data center has high temperature requirements and requires 365 days of constant temperature throughout the year. However, in fact, the temperature in different locations is different within the data center. If the ventilation is not good, the temperature in the same data center may vary by a few degrees, in this way, the temperature at the local location is relativel
