Computer optical drive due to often read disk friction, as well as some other reasons, will appear can not read the disk, the following for you to explain the CD drive does not read the possible causes and solutions! If an optical drive does not read the disk, we first add electricity and put a genuine disc to see if the panel lights flashing, there is no "Tatsu, Da, da" sound, if there is, then we can con

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

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

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

The installation of protocol-based (such as Gigabit Ethernet) networks boosts the rapid increase in the use of optical cables in Lan, which can meet the increasing bandwidth and transmission speed requirements. Multi-mode optical fiber cables are especially used for Gigabit Networks) and single-mode optical fiber cables are widely used in buildings as high-speed

The existing FTTH technology mainly includes the passive optical Network PassiveOpticalNetwork -- PON) Access Technology and the active Switched Optical Network ActiveOptical Network -- AON) access technology. They have their own advantages and are suitable for different application environments. Based on the characteristics of residential districts in China, this paper compares the advantages and disadvant

Resolution: multiple causes of optical fiber attenuation 1. The main factors that cause the attenuation of optical fiber include intrinsic, bending, extrusion, impurity, uneven and docking. Intrinsic: it is the inherent loss of the optical fiber, including the secondary scattering and the inherent absorption. Bending: When the

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

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
