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

Several problems should be noticed in the connection of optical cable. 1. Note the depth of the knife when opening the optical cable. The key to open the outer sheath of optical cable is to master the depth of the cutting tool, otherwise it is easy to break the fiber. In the actual operation, should rotate the sheath cutting knife, while observing the incision,

This paper introduces the main technology and method of opening CD-ROM in Delphi programming environment, the program is hosted in the status bar by pallet, which can be set up to boot with the system, not only to control an optical drive, but also to dynamically detect the number of optical drives on a computer, create the corresponding control menu, Implement selective control of the

Optical drive is our common optical storage device, but the optical drive is also a computer system easily damaged equipment, a CD-ROM drive is 23 time will expire. The common failure of the optical drive besides the decline in the ability of the bald-headed aging, there are some unusual mechanical faults. I have recen

Comparison of several types of Integrated Wiring and optical fiber cables What is indispensable in the process of Integrated Wiring is optical fiber cables. What are the advantages of optical fiber cables? The cable type should be comprehensively considered from the cable usage, required transmission capacity, transmission bandwidth, and price. Cable types inclu

The Optical drive consists of three parts, mechanical parts, electronic components and optical components, which are more complex than ordinary floppy disk drives and hard disks in use and maintenance, and the fault analysis and location are more complicated. The failure of the optical drive usually has interface fault, system configuration failure,

A friend of the author works in China Telecom and is mainly responsible for the fiber optic business of China tietong. At a recent meeting, he told me about several failures encountered during Optical Fiber maintenance. The author selects two of the most representative introductions for readers, I hope you will learn from the article and reflect on the whole process of solving the problem. Fault 1: multiplexing segment codes caused by SDH and their ha

Parallel Optical Interconnection Technology Along with the digitization process, data processing, storage and transmission have developed rapidly. High bandwidth makes short-distance Interconnection a bottleneck for system development. Due to factors such as loss and Crosstalk, the transmission distance in the case of high bandwidth of copper wire-based electrical interconnection is limited, and the cost also increases. In addition, excessive cables w

One, keep the optical drive, CD-ROM clean The optical drive uses a very sophisticated optical component, and the most feared is dust pollution. The dust comes from the whole process of loading and exiting the disc, and whether the disc is clean or not is directly related to the life span of the optical drive. Therefo

The optical fiber access network is still quite common. So I studied the learning notes about the optical fiber access network and shared them here. I hope they will be useful to you. FTTH), as the name suggests, means that the optical fiber access network directly enters the residence or office space of each user. The Backbone

Common Faults of optical drive, in addition to the decrease in the reading capacity of aging bare heads, also have some uncommon mechanical faults. I have encountered an example recently. One Optical Drive, good reading capability, has never been repaired. Recently, according to the warehouse, I feel the slow response of the optical drive, the slow pop-up of t

the motherboard does not recognize the solution for the optical drive: 1. Plug the optical drive data line again or switch to a data line, change the location of the optical drive jumper, restart; 2.BIOS Verify that the IDE channel of the optical drive is not set to Disabled or closed; 3. Right click on "My Computer

Band Cable The optical fiber cables are made from multiple single optical fiber cables by coloring, stacking into bands and secondary plastic bands. The optical fiber has two types: encapsulation and edge adhesive. The former can withstand horizontal pressure and the latter has a thinner thickness. Each band can contain 4, 8, 12, or 16

In the process of computer use, hardware problems are often encountered phenomenon, especially the optical drive failure. such as optical drive does not read the disk, the optical drive does not play automatically, disk drive read error and so on. Now this site summarizes the following 7 optical drive common failures,

High-density optical fiber management faces two challenges: protection and maintenance. Nowadays, with the surge in data services, people have higher requirements on the number and capacity of data transmission, and the construction of large data centers is also growing, with 10 Gb transmission gradually being used. It is understood that 10g transmission methods include 10G optical fiber and 10g copper cab

SDH is a very mature and strict transmission network system, it has been the birth of a wide range of application support, has become the world's core network of the main transmission technology. China from 1995 on the main line began to turn to the SDH network, China's SDH transmission network is to support the number of fixed telephone users in China as the world's first network of telephone users, the current operators of the metropolitan area network is mostly using SDH system. But in the d

Iimax®Solutions has rich experience in optical fiber cabling and LazrSPEED®High-performance products such as TeraSPEEDTM, InstaPATCHTM Plus, and LC connector. After years of research, the IMAX Laboratory analyzed the cost of the complete Optical Fiber System and concluded that the optimization of NM applications on Multi-Mode Optical Fiber enables the most benefi

Maybe many people do not have a special understanding of the man optical cable line. Next we will introduce in detail the overall design and technical application of the man optical cable line. How to build a Metro optical fiber network? First, it should be based on the network structure of the man. Second, according to the construction idea of the man, the topol

Broadband optical fiber access network is a common access method, but its implementation is complicated. We need to make full preparations in the early stage, A reasonable plan can be designed to avoid problems in subsequent work. 1.
