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

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

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

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

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

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

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

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

Optical Fiber Network Fault Test Equipment Analysis In recent years, as people have higher and higher requirements on the rate of broadband, because the performance of optical fiber is better than that of copper cable, it has been widely used in the backbone construction of broadband projects. At the same time, due to the increasing coverage of optical fibers, fiber
