Introduction Ethernet Passive Optical Network (EPON) is an Ethernet-based, point-to-point optical fiber access technology. It combines the simplicity of the Ethernet technology and the efficiency of the PON network, it is the best way to achieve fiber-to-user access networks in the future. Currently, all Protection Switching methods used in the EPON system require redundant PON modules, which are costly an

Before giving you a detailed introduction to the technology of the optical fiber access network, let's first understand the structure of the optical fiber access network, and then fully introduce the practical application of the technology. The topological structure of the optical fiber access network refers to the geometric arrangement of transmission lines and

placed in floor distribution boxes according to the principle that Splitter is as close as possible to users. Obviously, this ideal layout highlights the inherent advantages of PON, but it will inevitably lead to the following problems: first, high-core optical cables are required from the central data center to the residential area, such as 3000 residential areas, in-16-core computing, nearly 200-core optical fiber cables are required. At present, o

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

Nowadays, optical transceiver network devices are increasingly used in our network engineering. They are used in small-scale optical fiber trunk connection solutions, so it is better to use optical fiber interfaces for switches in large-scale optical fiber trunk. Because of the various types of optical fiber, wavelengt

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

purchase of vrouters, vswitches, and other network devices is also very important.Internet cafes have diversified network application types and have high requirements on network bandwidth, transmission quality, and network performance. network applications must integrate advanced, multi-service, scalability, and stability, it not only meets customers' needs for simultaneous transmission of voice, video, and data over a broadband network, but also supports a variety of new business data processi

Many friends do not know how to set the fiber-optic router, the next small series will be for the small white friend all-round introduction. How to set up fiber-optic router setup graphics and text tutorial In fact, the fiber optic cable and our ordinary telephone line is similar to the difference, the difference is that

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 optical fiber access technology is worth learning a lot. Here we mainly introduce the features of China's FTTH target market, this section describes the high investment in FTTH Network Construction from a development perspective, and avoids blindly requiring full-service access. So far, fiber-to-household fiber-to-home-FTTH has been widely used in Japan and t

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

At present, the development is relatively mature, and some products are applied to engineering D
