Q: How to relay submarine fiber optic cables?: At present, the number of fiber pairs in each submarine cable is limited to 4 or 8. In addition, the housing standard repeater can accommodate 8 fiber amplifiers, but the 4 is enough for optical fiber, and the shell model can accommodate the repeater optical amplifier this is more than 8 times, is suitable for occasions of fiber. Amplifiers with relay submarine cables are typically about 50 kilometers apart, about half the length of the land long haul fiber optic cable system. This is necessary because the length of the submarine optical cable system is often thousands of kilometers, much longer than that of terrestrial optical fiber cables. In submarine optical fiber cables, the gain of optical amplifiers should be kept at a low level, usually only about 10dB, which is to control the spontaneous emission noise and nonlinear effects of amplification, and these effects are accumulated along the length of optical fiber cables. The input power of high and low gain power is helpful to balance the entire spectrum of the optical amplifier, this point is very important, because after the 100 amplifier, small gain difference will accumulate a huge problem. The Raman amplifier in the last section of the optical fiber can not only amplify the signal of the optical amplifier, but also realize the gain equalization in the whole WDM spectrum. The current submarine optical fiber cable system uses only C band erbium doped fiber amplifier, but because of the increase of single channel rate and multiplexing wavelength, the capacity of submarine WDM system has been greatly improved. Early WDM submarine fiber optic system, each fiber transmission 4 2.5Gbit/s channels, such as 4 pairs of optical fiber, the total capacity

Q: The role of repeaters?: The relay mode (1. it can enhance your home wireless router WiFi signal, such as your router placed in the library, and you often surf the Internet where is the bedroom, if you study the signal for the 5 case, the living room for the 3 grid, and 1 bedroom lattice or not, then you can put this product in the living room, simply set your bedroom to search the signal becomes a full grid! You can surf the Internet in the bedroom comfortable 2. it can extend your home wireless router WiFi transmission distance, such as your wireless router transmitted WiFi signal coverage range is 10 meters, and you need to the Internet is 20 meters, you can put this product inserted in your main routing signal area (such as 8 meters around the place) in a wireless relay, you can put your wireless router WiFi signal coverage to 20 meters Used locally.)

Q: Is the repeater unable to connect to the network?: In addition, consider the following installation techniques:1. install the relay first in a very good signal position. In order for repeaters to work properly, doing so can greatly reduce the problem.2. upgrade the firmware of the repeater. Before the installation process, check that your repeater has the latest firmware version.3. configure the IP address. Make sure that the address of the repeater is unique and that it belongs to the IP address range that the wireless network connection can confirm. In most cases, the default IP address can be used, but you need to check the existing access point to confirm it.4. configure SSID. To set it exactly the same as the SSID on the existing network. If this step is not made, the repeater will never work unless the repeater fails, and it automatically scans the neighboring access points, automatically configuring this configuration for the user.5. configure radio frequency channels. The user needs to set up radio frequency on the repeater so that it matches the settings on the existing access point. This is similar to that of SSID. If the channel is set differently from the access point, the repeater will not work properly.

Q: Can repeaters land without cables?: Repeaters can be plugged in directly. Otherwise, the relay function cannot be reached.Method for use of repeaters:1, turn on the repeater;2, repeaters connect to wireless networks;3, set up the name and password of the repeater, you can provide a wireless network for your mobile phone.

Q: How can wireless AP (trunking) be used to connect wireless routers that shut down SSID broadcasts?: Either switch on the radio or use the cable. So far the repeaters on the market are like this!

Q: What is the repeater used for?: Repeaters (Repeater) work at the physical layer of the OSI, the center of all nodes on the LAN, which amplifies signals, compensates for signal attenuation, and supports remote communications. Repeaters are a small invention designed to push your network signals so that they can be transmitted farther. It's like a drink stand in a marathon. When the signal passes through a repeater, the network signal picked up a cup of drink, drink, the rest of the poured into his head, throw away cups, if convinced that no one saw them, jumped on a car. Due to the effect of transmission line noise, carrying digital signal or analog signal can transmit information in a limited distance, repeater function is regenerated and sending the received signal, thereby increasing the signal transmission distance. It is the most [1] simple network interconnection device, connecting two or more network segments of the same network. If the length of the cable Ethernet Repeater often use bus standard, thinnet each maximum length of 185 meters, up to 5, thus increasing the repeater, the maximum length of the cable network can be increased to 925 meters. In general, the network at both ends of the relay is a network segment rather than a subnet. Repeaters can connect two LAN cables, re - timing and regenerating digital signals on the cables, and then send them, which are typical functions of the first layer, physical layer, in the OSI model. The effect of relay is to increase the coverage area, such as Ethernet LAN [2], the maximum length of standard single signal transmission cable is 500 meters, but using the repeater cable to connect 4, Ethernet signal transmission cable up to 2000 meters. Some brands of repeaters can connect cable segments of different physical media, such as thin coax cables and fiber optic cables. The repeater sends only data from any cable segment to another cable, regardless of whether the data has erroneous data or is not suitable for the data of the segment.

Q: What is a repeater for?: The repeater is the most simple network interconnection equipment, mainly to complete the physical layer, is responsible for the physical layer of two nodes according to a transmission of information, copy, adjust and complete the signal amplification function, in order to prolong the network length. As a result of loss, the signal power transmitted on the line will be gradually attenuated, attenuation to a certain extent will cause signal distortion, and this will lead to a reception error. Repeaters are designed to solve this problem.

Q: Why is a wireless router sent by telecommunication disconnected from the network?: Access point B, as a wireless signal source, is set to the basic AP form. Therefore, the location can be either a wireless router or a wireless repeater. Let's take the TL-WR340G+ wireless router as an example.First, use the router's default management address, 192.168.1.1, to access the router management interface. Then click the basic settings in the wireless parameter to see the router's wireless configuration at this time. Write down the SSID number of the wireless network, "TP-LINK_74971E""At the same time, the MAC address of the wireless state is recorded in the running state of the management interface. 00-21-27-74-97-1E"At this point, the wireless router does not need to do any other settings.

Q: Switches, routers, repeaters, difference?: It is widely used in various occasions. The hub works in a local area network (LAN) environment, like a network card, applied to the first layer of the OSI reference model, and hence is referred to as the physical layer device. The hub is internally interconnected with electrical appliances. When the LAN environment is maintained as a logical bus or a ring structure, a physical, star, or tree network structure can be built entirely on the hub. In this respect, hubs play the role of multi port repeaters. In fact, the hub is actually a repeater, the only difference is that the hub can provide more port services, so called multi port repeater hub.
