Remember to enable the software drive and enable it again in CMOS to speed up the startup. The software drive is available, but not the optical drive. I saw the CD drive detected on the motherboard in CMOS. I think it must be a system problem. I checked the information on the Internet and found that, it is likely that the driver in the ide ata/atapi controller in the Device Manager has a problem. Program The device type in is changed to none. It turn

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 indi

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

Virtual optical drive is a kind of simulated optical drive (CD-ROM) tool software, you can generate and your computer installed on the optical drive function identical virtual optical drive, General optical drive can do the same thing virtual

With the extensive laying and use of optical fiber lines, the reliability and security of optical fiber communication systems have attracted more and more attention. Due to the vast territory of China, the terrain and landform are quite different, which may cause many dangerous factors to optical cable lines, including various natural factors and man-made damage

The biggest advantage of integrated all-optical switches is that they can easily expand to the interconnection, grid-like and ring-like hybrid networks, and grid-shaped networks, which cannot be achieved by other switch products. To reduce operating costs and increase revenue, carriers are keen to adopt new smart optical networks based on new-generation optical d

Over the past decade, the optical fiber industry has made great progress. However, there are a lot of end-to-end technologies, products, processes and programs to choose from. It is very difficult to choose a suitable solution in the application, at the same time, it will also affect the speed of work and the effective use of costs. Advances in machine and die-making tolerances, factory automation, and adhesives provide a wide range of options for fib

Absrtact: Firstly, this paper introduces the expansion of MPLS to optical network, secondly, this paper expounds the application of the traditional electric domain switching technology in the optical domain, and finally analyzes the all-optical Internet solution based on label switching: Multiprotocol wavelength label Switching (mplms), lobs switching based on la

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 on-site test of optical cable construction is very important. It is used to prepare for the overall commissioning of the optical terminal. The optical fiber test items in the optical fiber have the measurement of transmission attenuation. for Multimode Optical Fiber, tes

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

After using the optical drive frequently, the optical drive will inevitably occur some faults, after careful consideration of these failures, we may not be difficult to find that a part of the failure is not caused by the quality of the optical drive itself, but our improper operation or software set up errors caused by these factors caused by the

sun and rain, the water is split from the thin area of the outer skin, make the external conductor metal layer or metal mesh) corrosion. When the fault is checked with A multimeter, If the measured loop resistance is much higher than the original cable loop value, it proves that the outer conductor is seriously corroded. If the measured loop value is infinite, it indicates that the outer conductor is broken after corrosion. In short, there are many methods for detecting coaxial cables. As long

Do you remember the previous topic about "Optical Fiber for the future? Regardless of the answer, we need to pay close attention to the development of optical fiber technology and the capabilities of suppliers. At the same time, combined with application guarantees, we can ensure the maximum return on investment from the most critical fiber network in the modern data center. Industry standards also need to

How to perform Optical Fiber fusion and testing? 1. Optical Fiber Connection (1) optical fiber connection. The principle of optical fiber connection should be followed: when the number of cores is equal, it must be connected to the corresponding colored optical fiber in the

In Passive Optical Network (PON), the difficulty of Installing Optical Fiber Links and passive devices must be re-examined by the current standard testing technology. One of the other challenges encountered by the testing technology is that the 1490nm wavelength brings special difficulties to the OTDR. When the splitter is installed for testing, OTDR must face the challenges of high loss and difficult signa

Since the 1990s, Wavelength division multiplexing (WDM) has been deployed on a large scale in telecommunications networks, and the system's transmission capacity has increased by one times every 12-18 months. However, the control and management of optical networks remain in the traditional sense of SDH networks: The optical layer is simply a simple transport medium in the network, and its main function is t

1 Overview At present, after completing the network transmission infrastructure construction, China's major communication operators have made full use of the bandwidth of the existing transmission link and sought new value-added communication services to increase business profits. The implementation of e-commerce and e-government, as well as the development of telephone bars, Internet cafes, and other small-and medium-sized Telecom customers have seen the recent boom in Man and the increase in

system. They can be achieved through coaxial cable, optical cable, wireless or microwave. The video transmission system is the system's image signal path. A sound video transmission design is a very important part of the video monitoring system. If a well-built system selects cameras, lenses, monitors, and video recorders that can produce or process high-quality images, but does not have a good transmission system, eventually, the images seen on the

With the rapid development of broadband multimedia service and optical fiber communication technology, optical fiber communication technology has been used more and more widely in the access network. In the past, optical fiber network is mainly to meet the needs of transmission network construction, access to the layer of fiber optic cable needs less, a small num
