Small series for everyone to analyze the "system can not find the optical drive computer can not find the optical drive how to do?" The loss of the optical drive is most often when we install new software or new drivers, or we accidentally modify the CMOS settings or Config.sys configuration, and also because the machine is infected with viruses and so on. Hard
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
Today, the competition in the access network market is fierce. When deploying fiber-to-Building (FTTP) networks, it is usually difficult but necessary to make a budget early. This is because business providers should not only consider the initial installation fee, but also the unexpected business operation and maintenance costs. A large number of cost budget models prove that in the design and construction stages, the correct method for connecting FTTP networks in different segments is more accu
I. Basic knowledge of optical drive Before you choose a good CD-ROM drive, understand some of the concepts about the optical drive. First I say what is CLV and CA V disc and hard disk work in a very different way, the disc of the hard disk is divided into concentric circles, these concentric circles become the track, each track is divided into a number of sectors, the file is stored in these sectors, there
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
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
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
The optical fiber access network is worth learning a lot. Here we mainly introduce the technical features of the optical fiber access network. The optical fiber access network refers to the access network with the optical fiber as the transmission medium in the access network. The
Optical Flow Method Reprinted from yaoyi big white blog http://www.linyaoyi.com is also lamented on the network on the Optical Flow Method of Chinese information too little, so I plan to write snacks, because I have just come into contact with the optical flow method soon, if you are not talking about anything, I hope you can give me more information. T
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
All-optical switch features better performance and richer functions. The performance improvement will build a broad platform for more new applications, but with the ability to process IP layer or even higher layer data packets. 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, whi
Optical fiber jumper (also known as optical fiber connector) is a Connector Plug installed on both ends of the optical fiber, used to achieve optical link activity connection; one end is equipped with a plug is called pigtails. Optical fiber jumper (also known as
How to differentiate between single-mode and Multi-Mode Optical Fibers Single-Mode Optical Fiber The core of a single-mode optical fiber is fine, so that the light can be directly transmitted to the center. We recommend that you use this function when the distance is long. In addition, the distance loss of a single-mode signal is smaller than that of a multi-mod
1. Mainstream Optical Network Technology 1. New Optical Fiber Technology The optical fiber production technology is now mature and is now in mass production. Today, single-mode optical fiber with zero dispersion wavelength λ 0 = 1.3 μm is widely used, the single-mode optical
Exploration phase of China's optical cable manufacturing in Since the application of the first practical multi-mode optical fiber cable in China in 1982, China's optical fiber manufacturing and industrialization have gone through 30 thoughts and experienced three ups and downs once a year, today, the world's largest optical
Currently, the access network technology is widely used, and the access network technology is also very commonly used. So I have studied the problems related to the access network technology construction planning and practical application. I will share with you here, I hope it will be useful to you. With the rapid development of broadband multimedia services and optical fiber communication technology, optical
Introduction to Optical Fiber Temperature Measurement Technology in data centers The data center has high temperature requirements and requires 365 days of constant temperature throughout the year. However, in fact, the temperature in different locations is different within the data center. If the ventilation is not good, the temperature in the same data center may vary by a few degrees, in this way, the temperature at the local location is relativel
First, we should understand optical fiber communication. Optical fiber is short for optical fiber. It consists of a fine glass wire with a diameter of about 1mm. It is transparent and slim. Although it is fine than the hair, it has a guided wave structure that closes the light in it and transmits along the axial direction. Op
The development of the network puts forward new requirements for Optical Fiber No matter how the next generation network develops, it will surely reach three levels: the IP address world at the service layer, the light world at the transmission layer, and the Wireless World at the access layer. The next-generation transmission network requires a higher speed and a larger capacity. This is not a fiber optic network, but the development of high-speed ba
