Among the many Internet access modes, the operators of Internet cafes usually choose the

The PK of fiber access and ADSL access in the network is expected to help you. 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 are also varied. At present, the international Internet access solutions include optical fiber, ADSL, satellite broadband access and other

The test of the optical cable cabling system is a necessary step for project acceptance. It is also the final process for the project contractor to honor the contract with the real estate owner. Only after the system test is passed can the cabling system be completed. The connectivity of devices is the most basic requirement for wiring system testing. The effectiveness of jumper systems can be easily tested. It is relatively difficult to test the indicator data of communication lines, generally,

Now, the position of Optical Fiber Ethernet switches in the switching industry is becoming more and more important. Here we mainly introduce the comprehensive performance of Optical Fiber Ethernet switches. Because Fiber Optic Ethernet switches can provide high-speed and low-cost fiber access solutions, many manufactur

Analysis of Optical Fiber Application Technology Based on Cabling Technology 1 key points of data center optical fiber design (1) minimum allowable bending radius: In which case the installation of optical fiber is much easier than that of coaxial and UTP copper cables. The most important factor in cable installation is to keep the minimum bending radius of the

Future development prospects of multi-mode optical fiber in Optical Networks At present, the requirements for data transmission are growing exponentially, so the requirements for network transmission speed are also constantly improved. Multi-Mode Optical Fiber allows different modes of light to be transmitted on one optical fiber. Because the core diameter of

The problem at the optical fiber connection is the main cause of network failure. Therefore, the detection of the optical fiber end is crucial. This article discusses three main face detection methods. The optical fiber end surface processing quality has a great impact on the overall performance of the optical fiber co

The Fiber jumper (also known as the optical fiber connector), which is the optical connector to access the optical module, also has many kinds, and can not be mutually used. The SFP module is connected to the LC fibre optic connector, while the GBIC is connected to the SC fiber optic connector. The following is a detailed description of several commonly used opt

Optical Fiber Transmission Distance exceeds 12 thousand km without relay Optical Fiber communication (fiber-optic communication) refers to the use of optical and optical Fiber (optical fiber) to transmit information, is a type of wired communication. The optical

1. To provide wider spectral bandwidth for the optical fiber of the metropolitan area Network, because the typical distance of the metropolitan network is less than 80 km, the optical amplifier is rarely used, and the group velocity dispersion of the fiber is not the primary limitation. More importantly, the metropolitan area network typically requires support for a large number of users and tends to increa

What is a vswitch fiber port? What is the optical fiber port of a vswitch? What is the difference between a fiber-optic port of a vswitch and a common port? After reading this article, you will know a lot and hope you can learn more. Cascade uses both common ports and special MDI-II ports. A straight-through cable should be used when the two ports that are cascad

There are many broadband Internet access methods. For enterprises, ADSL and optical fiber are currently popular. The full name of ADSL is an asymmetric digital user line. It is a popular broadband Internet access method and a technology that provides broadband data services through copper telephone lines. Optical fiber is short for optical fiber. Optical

In various technical means to achieve broadband access, the optical fiber access network is the most suitable for future development solutions, especially the ATM Passive Optical Network (ATM-PON) it is almost an economical and effective way to integrate broadband access.
