The solution for handling 300 or less Ge Fiber switches in Internet cafes is analyzed. The solution for Internet cafes with 150 computers is different from that for Internet cafes with 200 computers. The solution for medium-scale Internet cafes is provided below. Internet cafe owners can check their seats and find their own methods. About 150 Internet cafes The network center uses the RHS4616GMS fully-managed Gigabit Optical Fiber switch. It provides

Generally, we define a metropolitan optical network as a light transmission network spanning dozens of km to hundreds of kilometres, generally serving large, business-focused urban areas. Metropolitan Optical Network bridging between long-distance network and access network, the access network in the enterprise network of various services connected to the backbone of the operator network. In recent years, w

Ribbon cable A fiber optic cable that is machined by a plurality of single fiber fibers, which are colored, stacked into strips, and two times molded. There are two kinds of optical fiber, namely the encapsulation type and the side-viscosity type, the former can withstand transverse pressure, the latter thickness is thin. Each band can have 4, 8, 12 or 16 fiber. In-band fiber spacing is 0. 28mm (for 4, 8) and 0. 3mm (for 12 and 16), neatly arranged,

The use of fiber-optic Ethernet technology can make the fiber access solution more optimized and reasonable. At the same time, many manufacturers have launched their own fiber-optic Ethernet products, and I believe that the market competition will be more intense. Fiber-optic Ethernet technology is the integration and development of the two mainstream communication technologies, namely, Ethernet and optical network. It integrates the advantages of Eth

In recent years, the main development trends of optical communication technology include capacity improvement, further intelligence, optical transmission of Carrier-class Ethernet, and fiber-to-the-Home. Along with the development of these technologies, optical communication testing technology has also developed rapidly. The development of the

Optical Fiber Communication is a communication mode in which various electrical signals are modulated by optical fibers. Optical Fiber Communication is different from wired communication. The latter uses metal media to transmit signals, while optical fiber communication uses transparent

The fine fiber is encapsulated in a plastic sheath so that it can bend without breaking. Typically, a transmitter on one end of the fiber uses a light-emitting diode (light emitting diode,led) or a laser beam to transmit the light pulses to the optical fiber, and the receiving device on the other end of the optical fiber detects the pulse with the photosensitive element. In daily life,

Optical wireless communication technology, or FSO (FreeSpaceOpticalCommunication), is a broadband access method. It is a product of the combination of optical communication and wireless communication. It uses the beam signal to pass through the atmospheric space, instead of transmitting signals through optical fiber. The structure of the Access System of this tec

Technological breakthroughs make it easier for people to lay optical fiber at a long distance The broadband frequency comb ensures that the crosstalk between multiple communication channels in the same optical fiber can be eliminated. For a long time, one of the major problems with optical fiber is that the more energy you add to the signal, the more serious the

Core functions of the all-optical perimeter monitoring and warning system 1. Long-distance intrusion monitoring The entire process along the optical fiber laying area is monitored in real time at any point around the clock without interruption. 2. intrusion locating When detecting the threat of intrusion, the system can locate the intrusion occurrence point in real time based on

1 Avoid physical damage. If you often take your CD-ROM drive out, please be sure to take care of the light, try to avoid vibration, to protect the precise positioning of the laser head. Do not be brutally disassembled. When closing the optical drive door, do not use the hand to push, should use the panel in and out of the box key to avoid the disk mechanism gear dislocation; 2) attention to heat dissipation. Poor heat dissipation can result in failur

Many motherboards now support both ATA100 and Str. But the two new technologies, ATA100 and STR, are "delicate", with motherboards and hard drives that support both new technologies, and don't necessarily allow us to easily enjoy the benefits of them, and in some systems some of the hardware may be disruptive to you. The author recently encountered this kind of trouble: Love machine into the "Waiting" state, my Arctic Shunguang drive always sleep awake, causing str dysfunction, to hot start to w

A computer assembly, the work has been normal, installed on the previous optical drive failure, the use of new optical drive CD and VCD CD-ROM normal, but use it to install software, the computer automatically restart. Sometimes a reboot occurs when two optical drives are used at the same time. First, the optical
