I. Question proposal: Now the broadband access of China Telecom has changed. The infrastructure construction is fiber-optic, and fiber cables are dug everywhere. In communities with fiber-optic cables, telephone signals are also fiber-optic, therefore, the ADSL provided by China Telecom was replaced by the Huawei hg1

After a period of development, cerl2 has stabilized and it is time to unveil it. Unlike cerl2's original vision, cerl2 did not eventually become a language. It evolved programming models on cerl and formed multiple sub-databases. The two major sub-databases are async and Venus. The bottom layer is async, which needs to be packaged for different platforms to form a network layer. You can compare async with boost ASIO. The two are similar, but they have different programming concepts. Venus is a p

1. The role of fiber in KilimFiber is used to manage and save the state of a function stack frame in the call hierarchy during task execution, where the function stack frame is the same as the function stack frame in the JVM runtime, but fiber does not copy all the information in the function stack frame intact, such as all variables in the local variable table , but after code analysis there is a selection

tplink Router Optical fiber Setup Method First, fiber optic cable, computer, wireless router connection method Fibre-optic cable because there is no cat, you need to connect directly to the router, and you need to connect to a special WAN port on the wireless router, and there are four other core LAN ports that users connect to the computer. In addition, we also need to connect the router for the wireless

There are many different classifications of fiber optic transceivers, and most of the attention is being paid to categories that are differentiated by fiber connectors: SC connectors, fiber transceivers, and fc/st connectors. When using a fiber-optic transceiver to connect to different devices, you must be careful to

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

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 understood as an upgraded version of GBIC. The size of the

This content is nothing for experienced friends, but it can be useful for new users who just entered the industry. There are two types of optical fibers: Single-mode Optical Fiber Single-mode Fiber): Generally, the optical Fiber jumper is yellow, the connector and protective sleeve are blue, and the transmission distance is long. Multimode Optical

With the development of China's access industry, optical fiber access technology has become one of the mainstream technologies, and many branch technologies have emerged. GPON can meet the requirements of optical fiber access network. The increasing popularity of the optical fiber access market brings a rapid development opportunity for the new generation of opti

A network testing team of Siemens Germany, supported by the European Union, recently announced that they have successfully tested the passive optical fiber network. This test not only made a new breakthrough in the speed of data transmission connected to the home or office, but also expanded the transmission coverage. On the passive optical fiber access test network, the data download rate tested by the te

Background: 1: two high-definition set-top boxes in the home, one optical fiber broadband (20 m/1 m) 2: Optical Fiber CAT (a device provided by China Telecom, similar to a router) has a total of four Network Ports, two Network Ports lan1 and lan2 are used to connect IPTV, and one network port lan4 is used to access the Internet. 3: network port 4 connects to the home wireless router 4: After the telecom

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
