Q: How to relay submarine fiber optic cables?: Based on these definitions, a relay free submarine fiber optic cable is developedThe span of the system can reach about 400 kilometers, and the transmission distance of the relay system can reach thousands of kilometers.The addition of an optical amplifier will lead to more restrictions on the relay submarine fiber optic cable system. One problem is: the cable itself must provide electrical power from the junction of the shore, but the power transmission capacity of cable is limited, which limits the total number of amplifiers, which also limits the number of fiber optic cable.

Q: What is the role of optical repeaters in fiber communications?: Optical repeaters are devices that compensate for the loss of optical signals and eliminate the effects of signal distortion and noise in long distance optical fiber communication systems. It is a kind of optical fiber communication equipment. Its function is to extend the communication distance. It is usually composed of three parts: optical receiver, timing decision circuit and optical transmitter, and auxiliary equipment such as remote power supply, receive, remote control, telemetry and so on. The optical repeaters will receive weak light signals from the optical fiber and convert them into electrical signals by the optical detector. After the regeneration or amplification, the light source will be excited again and converted into strong optical signals to be sent into the optical fiber to continue transmission.

Q: How do you use a wireless router to connect WIFI signals to another wireless router?: Step two will be second router and computer links, computer IP is set to second automatically, and then press the specification of the router landing second router settings interface, here, we choose the fixed IP link, the WAN port IP address is set to 192.168.1.2Then set the LAN port IP to 192.168.2.1, and then determine the computer IP address to 192.168.2.2, from the first router on the network link, in the second routers, set up successfully.If the second router is wireless receiver or repeater, and setting method.

Q: WIFI how does the repeater amplify the amplified signal?: Like repeaters in old Ethernet, repeaters in old token ring networks have the same principle: signal reduction and amplification.As long as the signal is generated by electricity, whether wired or wireless or waves will have an attenuation and distortion, attenuation is due to the distance from the distortion of interference, attenuation is inevitable, the distortion can be avoided or improved.

Q: What does "universal relay" mean by a router?: For example, a two storey upstairs and downstairs, only if a wireless router placed on the first floor, two floor, then the signal received may has been relatively weak, the third floor is probably not to search for a wireless signal, if we deploy a two floor is a wireless router, it can significantly enhance the two building a wireless signal, and can also cover the floor.

Q: What is the principle of fiber repeaters?: First, the transmission of optical signals is explained. When the transmission of the optical signal in the optical fiber with a longer distance and the signal decreased, when less than a fixed value when the optical receiver at the receiving optical signal can not correctly identify signal encoding, will lead to error, so at a certain distance from the optical fiber transmission, with a fiber optic repeater, the light amplification the signal can support long-distance transmission, similar to the gas station.

Q: How can I use a wireless repeater where there is no power?: If it is not 12V, it is usually necessary to add a conversion circuit, such as 12V, 9V, etc., for wireless repeaters.

Q: Switches, routers, repeaters, difference?: Routers: routers work in the third layer of the OSI model, the network layer. The router uses the network address defined on the logical layer of the network layer (that is, the IP address) to distinguish the different networks, so as to realize the interconnection and isolation of the network, and maintain the independence of each network. Routers do not forward broadcast messages, while broadcast messages are restricted to their respective networks. The data sent to other networks is sent to the router and forwarded by the router. Switch: LAN switch has many ports, each port has its own dedicated bandwidth, and can connect different network segments. The communication between the ports of the switch is simultaneous and parallel, which greatly improves the throughput of the information. To further improve performance, each port can only connect to one device bridge: the bridge acts on the data link layer of the OSI schema, which identifies the MAC address of the packet. In actual operation, the bridge compares the packet location of the received data to its known network segment address and transfers the data if the packet address is not in the same network segment.

Q: What is the meaning of intrinsically safe CAN repeater: It should be intrinsically safe CAN repeater. CAN bus because of its good error control ability,
