The Application of Fiber-Optic Ethernet switches is becoming more and more extensive. Here we mainly introduce the ACCESS scheme of fiber-optic Ethernet switches and its practical application problems. The fiber-optic Ethernet technology is the integration and development of the two mainstream communication technologies, that is, Ethernet and optical network. It
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 optical fiber to transmit light
4G investment over 240 billion Optical Fiber splitters will increase in demand
By 2014, China Mobile will build 0.5 million base stations with an investment of more than 240 billion yuan. The 4G wireless network will cover 340 cities and strive to expand 50 million 4G users, with the arrival of the 4G era, the demand for optical fiber splitters will increase dramatically.
Mobile communication is wireless a
When selecting the right optical cable for the data center, the application, distance, data transmission rate, and the difficulty and cost of future upgrades should be taken into account. Multi-Mode Optical Fiber has always been the choice of enterprise system network connection structure (ESCON) and related Switch Networks, and most modern SAN and LAN also adopt multi-mode optical fiber. Other applications
During the establishment of a LAN, according to the general standards of Integrated Wiring, the construction should use a network cable with a "meter" or a special "shaped number tube" at the crystal head on both sides ", the computer identification records corresponding to the "meter mark" or "number tube" are recorded in the cabinet.
Many units have a small number of computers. Later, some computers were added to form an inevitable lan. However, when the network was originally set up, the netw
The method of setting up TP link Fiber wireless router
1, first open the computer, and then any open a Web page, and then in the browser URL in addition to enter their own router login IP address, the following figure:
As shown above, to the author of the wireless Router for example, first in the browser address bar input 192.168.1.1 and then press ENTER, you can pop up the following User Login dialog box, we are the default user name an
Fiber-optic access broadband is faster and more stable than ADSL transmission, so many friends now choose the fiber-optic access when they install broadband. But when I installed the FTTB dialer under Windows XP, I encountered a problem:
Cause of failure
In Windows XP, follow the steps under Windows 98 to install the FTTB private dialer and enter your username and password, and the system requires
business broadband network, the broadband access network is undergoing profound changes. On the one hand, xDSL technology gradually from adsladsl2adsl2+ to provide a higher bandwidth VDSL2 upgrades, which also requires vdsl2dslam closer to the user side. With the increase of the number of VDSL2 Zhi, the requirement of efficient aggregation of large quantities of dslam is put forward. On the other hand, fiber is rapidly replacing copper wire as an ide
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 optical

The increasing requirements on network transmission capacity have promoted the further development of the 10 Gbit/s system. The IEEE Institute of Electrical and Electronics Engineers (IEEE) provides a description of the system configurations in LAN) and WAN in 802.3ae in terms of 10-bit Ethernet technical specifications.When the transmission speed of a Multimode system driven by an LED is 622 Mbit/s, the 10Git/s system can take full advantage of the cost-effective vertical resonator Surface Emit
Advantages of Optical Fiber
As the successor of SCSI technology, fiber channel technology has three main advantages compared with its predecessor: Connection distance, scalability and performance.
1. Advantages of connection distance
We all know that SCSI Cables cannot exceed 25 m at most, and this is only a theoretical value. In practice, when the number of devices on the SCSI channel exceeds 8, the connec
The optical fiber access network is still quite common. So I studied the optical fiber access network equipment in Internet cafes and shared it with you here. I hope it will be useful to you. As customers have higher and higher requirements on Network Stability and speed, the network devices required for Internet cafes must also have higher stability and reliability to ensure uninterrupted and stable networ

With the development of science and technology in the times, no matter what kind of enterprises have strict requirements on their own hardware facilities, the most popular switch is the so-called optical fiber switch, that is, a separate network of the entire storage can be connected to the enterprise LAN of the server.
It is characterized by the use of fiber channels with high transmission rates to connect
Cisco has launched the CiscoMDS9100 series of multi-layer Intelligent Optical Fiber switches. To meet the SAN needs of small and medium-sized enterprises, the Intelligent Optical Fiber switches are large devices, mainly to ensure data forwarding at a higher speed and accessibility.
It can also achieve seamless migration from a small SAN to a large-scale SAN, effectively protecting customers' SAN infrastruct
There are many areas worth learning about fiber switches in Internet cafes. Here we mainly introduce the fiber switches solution for Internet cafes of different sizes. Optical fiber is generally made from SiO2 Z SiO2) by special pulling process. It no longer uses electronic signals to transmit data, but uses optical pulse to transmit signals, it features high ban
Three fiber types are commonly used in building cabling systems: 62.5/125 μM multi-mode optical fiber, 50/125 μm multi-mode optical fiber, and single-mode optical fiber. With the development of ipvimax SCS, a new 50/125 μm optical fiber optimized for low-cost 850nm laser app
Methods to Improve fault locating accuracy of optical fiber lines
The continuous development of the economy is driving the constant upgrading of the information age. The transmission rate and capacity of copper cables cannot meet people's needs. Therefore, the optical cable market has ushered in unprecedented development. Nowadays, with the support of national policies, optical fiber cable lines are laid a
