1. What is GBIC?? GBIC is short for Giga bitrate interface converter. It is an interface device that converts Gigabit electrical signals into optical signals. GBIC is designed for hot swapping. GBIC is an Interchangeable product that complies with international standards. The gigabit switches designed with GBIC interfaces share a large market share due to flexible exchange. 2. What is SFP?? SFP is short for small form pluggable. It can be unders

What's going on with the automatic eject of the optical drive? Problem Description: Netizens just bought a new computer, found that the optical drive is always bouncing out of their own and automatically bounce in. have been so repeatedly, in the end what is the fault? Consult our computer engineer! CD-ROM automatic eject explanation: Under normal circumstances, when the

After reasonable management, two kinds of distortion factors (dispersion and self phase modulation) in optical fiber can cancel each other, so that the optical soliton can play its role. The color closing causes the pulse signal containing a group of wavelengths to diverge gradually with the increase of the transmission distance. Self-phase modulation (SPM) spreads the spectrum of light pulses horizontally.

The continuous growth of the Internet and the emergence of various new businesses, such as multimedia web pages, multimedia games, Multimedia conferences, and e-commerce, have led to exponential growth of Internet services. Due to the diversity and variability of services, the traditional core exchange network is no longer suitable for the needs of the continuous development of the Internet. This situation has prompted researchers to speed up in-depth research on WDM transmission and all-

Next we will study the advantages of all-optical switches. They can easily expand to the interconnection, grid-like and ring-like hybrid networks, and grid-shaped networks, which cannot be achieved by some common switches. At present, operators are keen to adopt a new smart optical network based on the new generation of optical devices. A typical example is an al

Article Title: Why is the drive in Linux not obedient. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. The operating method of the optical drive in Linux is different from that in Windows. This makes it inconvenient for some people who are new to the Linux operating system. I am going to give a more in-depth explan

G.652 Single-Mode Optical FiberThe single-mode optical fiber that meets the requirements of ITU-T.G.652 is often called non-dispersion displacement optical fiber. Its zero dispersion is located in the Low Loss zone of 1.3um window, and the working wavelength is 1310nm loss is 0.36dB/km ). The vast majority of optical f

With the continuous development of the Internet, the rapid growth of voice, data and multimedia services poses higher requirements for the transmission network's transmission bandwidth, interface methods and operation and maintenance. With the development of 40g synchronous transmission technology, wavelength division multiplexing technology, and ultra-long optical transmission technology, optical transmiss

The rapid development of the Internet has led to the further prosperity of the Internet bar industry. The access methods of Internet cafes are also different, and network networking solutions are also varied. At present, the international Internet access solutions include optical fiber, ADSL, satellite broadband access and other broadband access and DDN, ISDN and other narrowband access. Among the many Internet access methods, Internet cafe operators

The following describes FTTH access technical standards and deployment solutions, including how FTTH is connected to your network. As copper prices keep rising and the cost of optical cables keep decreasing, fiber-to-household (FTTH) services that provide bandwidth much higher than metal wire access are becoming the focus of ISP (broadband operator) promotion this year, in the near future, high-speed broadband will no longer be a dream for ordinary co

There are many broadband Internet access methods. For enterprises, ADSL and optical fiber are currently popular. The full name of ADSL is an asymmetric digital user line. It is a popular broadband Internet access method and a technology that provides broadband data services through copper telephone lines. Optical fiber is short for optical fiber.

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

The most basic switching unit in optical burst switching technology is burst data. Meanwhile, BCP and burst data in OBS are separated on the physical channel, and each control group corresponds to a burst data. With the rapid growth of IP services around the world, the demand for transmission network bandwidth and switch system capacity is increasing at an unprecedented rate. Currently, DWDM technology is used in the

Cable construction is roughly divided into the following steps: Preparation → route engineering → Cable laying → cable connection → engineering acceptance. 1. Preparatory work (1). Check the design materials, raw materials, construction tools and equipment are complete. (2). To establish a high-quality construction team. This is important because optical fiber construction is more stringent than cable construction requirements, any construction of

Dense Wavelength Division Multiplexing (DWDM) technology provides a huge transmission capacity for communication networks and gradually becomes a mainstream transmission technology. With the maturity of DWDM technology and the rapid growth of transmission capacity, traditional electronic exchange systems are under increasing pressure, and the introduction of optical exchange technology is becoming increasingly urgent. In contrast to the three

As optical fiber transmission technology matures and the price of Optical Fiber becomes lower and lower, traditional coaxial cable transmission is increasingly unable to adapt to the development of optical network today, it has the advantages of low transmission loss, long transmission distance, working bandwidth, and strong anti-interference ability, making it t
