Prepare to install broadband in the relocated house. Seeing the advertisement of China Mobile at the stairway, mobile broadband can be used for one month, and only 50 RMB per month for 2 m,If you think it is inexpensive, you can call 10086 for trial registration. It is very convenient to handle. You only need to register a mobile phone number and do not need the initial installation fee.In the afternoon, th

Any professional who has done network troubleshooting knows this is a complex process. Here are some of the most common fiber failures and possible factors for these failures, which will help users to have a base guess on network failures. Fiber breakage is usually caused by physical extrusion or excessive bending of the external force; Insufficient transmission power; Optical

Vswitch Optical Fiber ports are divided into many types, and their functions are quite different. Here we will mainly introduce some basic knowledge about common optical fiber ports of vswitches. Cascade uses both common ports and special MDI-II ports. A straight-through cable should be used when the two ports that are cascaded are normal ports (MDI-X) ports and MDI-II ports, respectively. Cross-cable shoul

Vswitch Optical Fiber port cascade connection mode and basic type when the two ports of mutual cascade are common port (that is, MDI-X) port and MDI-II port, should use a straight-through cable. Cross-cable should be used when both ports of mutual cascade are common ports (that is, MDI-X) or both are MDI-II ports. Whether it is 10Base-T Ethernet, 100Base-TX fast Ethernet, or 1000Base-T Gigabit Ethernet, the length of the cable used by the cascade swit

The EPON optical fiber access technology is still quite common. So I studied how to increase the network bandwidth of the EPON optical fiber access technology. I would like to share with you here and hope it will be useful to you. With the 1 Gbps fiber-to-the-Home (FTTH) technology, the deployment Speed of EPON fiber a

For many Internet cafe administrators, it is very important to correctly buy broadband routers for Internet cafes. With the rich Internet resources, many friends want to obtain resources through the network and even perform various entertainment through the network, the Internet cafe industry has become more prosperous. Internet cafes are a multi-person and complex environment. The speed and stability of Internet access are critical. Therefore, many I

With the rapid development of communication technology, telecom operators are constantly improving the transmission rate of single channels in WDM systems to meet people's needs for communication bandwidth. At present, a single wavelength WDM System with a transmission rate of 10 Gb/s is under construction, and a WDM System with a transmission rate of 40 Gb/s has entered our field of view. At the same time as the transmission rate is improved, the communication system performs polarization mode

I. Introduction and background In recent years, optical fiber communication systems have made great progress to meet the increasing bandwidth requirements. The main factors limiting the performance of single-mode optical fiber (SMF) systems include attenuation, dispersion, and non-linearity, as well as recently noticed polarization mode dispersion (PMD ). For a traditional single-mode optical

A Single-Mode Optical Fiber transmits only a single base mode optical fiber at a given working wavelength. It does not have mode dispersion, so the single-mode optical fiber has a very wide transmission band, used for long distance, large capacity transmission. The core of a single-mode optical fiber is very fine. The

The cabling system is widely used in multi-mode Z optical fiber due to a small number of trunk lines connected to the floor. in the horizontal direction, there is no suitable medium that can provide sufficient bandwidth, it also has the advantages of easy installation, low cost, and strong anti-interference ability. The new plastic optical fiber (POF) as the transmission media of the all optical

The first generation of wireless access technology in the the 1970s is microwave technology. Today, the microwave technology to digital, high frequency, broadband direction, very sui

Principle and sensing process of Distributed Optical Fiber Temperature Measuring System The Distributed Optical Fiber Temperature measuring system can be divided into three types based on the backward scattering principle: Based on Fourier scattering, based on Raman scattering, and based on Bayesian scattering. At present, the development is relatively mature, and some products are applied to engineering D

1 Introduction Nowadays, delay lines have been widely used in signal processing, radar, electronic countermeasure, and other fields. For example, the Unit delay device required for signal processing is a kind of memory, and the dynamic target display (MIT) there must be a delay line-another kind of memory. In electronic confrontation, the signal must be stored for a certain period of time before processing. For example, the receiver's radar signal must be delayed for a certain period of time be
