There are two routers in the home want to connect to use, or use someone else's network, want to pick up a router to use WiFi internet access, using a router cascade can connect two routers, convenient use of WiFi router.
There are two ways to connect a two router:
The first way: the route mode Cascade, the second level router and the superior router all have the routing function, two routers are two independent LAN
The second way: switch mode cascade, the second level router is equivalent to

1, 10Base-T: twisted pair cable, generally use RJ-45 connector; maximum effective transmission distance is 100 m from the hub, even the high-quality Category 5 twisted pair can only reach 150 m. The matching resistance is 120 Euro.
2. 10Base5: coarse coaxial cable with plug-in connector and baseband signal. The maximum supported l

At present, although optical fiber has become a buzzword, many related projects are also being implemented. However, due to the technical level, general demand and price factors, it is not possible to form a universal demand product in the market. Currently, copper cables are still the mainstream in network cabling products. The performance of cat5e and
to be converted from multimode to Single-Mode Optical Fiber for transmission. If a digital signal is used, it can be easily transmitted. In a single input and output mode, the optical distribution amplifier can be used to configure the conversion without any baseband signal attenuation during the transmission process.
If you have an existing optical fiber installation that needs to be upgraded, consider replacing all the current transmitters and receiving machines with the new digital multiplex
In accordance with the normal application of the topology of computers, routers, cats connected, if the corresponding router LED is not bright, this problem may be connected with the network cable, fault, port failure and other reasons, this article provides detailed troubleshooting ideas.
The WAN port LEDs are not lit

In the context of the large increase of global data traffic, data center construction tends to the direction of cloud computing, while the cloud Computing data Center will use 10G, even 40g/100g and other high-speed network applications based on fiber transmission, and the application of virtualization technology also put forward higher requirements for network transmission, Presents new opportunities for the application of optical fiber systems. While China's national standa
After the installation of the cable wiring system, the link transmission characteristics need to be tested, among which the main test items are the attenuation characteristics of the link, the insertion loss of the connector, the return loss and so on. The following is a brief introduction to the measurement of key physical parameters of optical cable wiring and troubleshooting and maintenance in the networ

This is a 10 MB (1010 Mbps = 10 million 1 and 0) system per second. It uses a large coaxial trunk network cable to connect the entire building, connect the workstation with a small coaxial network cable at an interval of 2.5 meters. Large coaxial network cables are often yellow, known as "coarse Ethernet
The Smart Home cabling system is the basis of the Smart Home System and the channel for its transmission. Next let's take a look at the cable types and common problems in smart home.

First of all, our most common network cable has 3 kinds
The first is: straight-through cable
The second type is: Crossover cable
The third is: reversing the cable
The first is through the cable, straight line, also known as the normal line or standard line, both ends of

standard uses Level F as a model, and the frequency range will be increased from the original 1000 MHz to the current MHz. From the perspective of the existing middleware standard and GG45 connector, these have higher transmission requirements in the above frequency range. However, this is only the application of the high-bandwidth shielding system. Here we will focus on the changes to the class-6 unshielded e-class standards.
