Q:What is the role of optical repeaters in fiber communications?

Optical signal transmission in optical fiber will have loss and dispersion, and non line letter effect will affect the transmission distance and capacity. The loss will affect the signal amplitude, and the dispersion will lead to fiber bandwidth broadening and error codeIn order to long-distance transmission must join the optical relay system in optical fiber transmission line, transmission loss and dispersion is used to compensate the signal. If not, the signal in long-distance transmission is too small and the occurrence of serious error, the receiver can not successfully received.The high cost of optical relay, optical amplifier after the optical amplifier is generally used instead of optical relay, commonly used Amplifier EDFA and Raman amplifier (EDFA), also have the dispersion compensation of dispersion compensation amplifier new.

Q:Elevator 3 party intercom, no repeater can connect how many meters

Now I have 5 party calls to the elevator and its headache, elevator do not understand the call equipment, equipment parameters do not provide, and rotten problems are much more prepared, wearing hundreds of meters, a fault, but also to find the wiring of the line.

Q:How to use a wireless repeater and wireless network card to make desktop computers online?

Network wireless repeater narrow said wireless AP, AP Access Point (wireless access node) abbreviation, it is equivalent to the wired network hub or switch, however, this is a wireless signal transmission function of the hub, it can be for a plurality of wireless Internet equipment to provide a dialogue meeting point.

Q:Can Tengda F6 repeaters be controlled by mobile phones?

The repeater is the most simple and inexpensive networking equipment under the LAN environment to extend the network distance, the operation of OSI in physical layer, the repeater has a regenerative amplifier function for the signal on the line, to extend the LAN segment length (only for connecting the same LAN segment).

Q:How does the relay set up the connection WiFi?

You know his password and can log on, but the signal is weak, you can use the wireless router to set up a relay mode, you can zoom in on the wireless signal. That is, extending the coverage of wireless signals.Introduce a method to see, which can be used for reference.

Q:What does a network node mean? What does a repeater do?. Generally speaking, thank you

As you said the most popular the most simple speaking is a network, two line inserting machine is a network node, but the cat with the home computer is not a repeater network line is too long, there will be a loss, error signal, the middle of a repeater to signal amplification, forward. A gas station.

Q:How to connect the router Tuoshi wireless bridge repeater

The relay mode allows multiple client links, and the bridge mode allows only authenticated client relays to be more advanced than wireless bridges. Wireless bridging means connecting two or more LAN or WAN wirelessly.

Q:Is the network repeater and the main route a signal or two signal?

Can be set to a signal, can also be different.

Q:What is the difference between the router's relay mode Repeater and the bridging mode Bridge?

As shown below, the host connected to Bridge 1 or Bridge 3 can communicate via the WDS link and the host to the bridge 2. However, the host connected to the Bridge1 cannot communicate with the Bridge3 host through the Bridge2.What's the difference between Repeater relay mode and Bridge bridge mode?In Repeater mode, the wireless signals, SSID, and encryption modes sent by TL-WR700N are exactly the same as those of the main AP, so after setting the Repeater, the wireless cannot search for the default TL-WR700N of the SSID. In the Bridge mode, the TL-WR700N can set its own SSID and encryption mode for wireless signals, which can be different from the main AP.TL-WR700N sets the Repeater mode as a relay amplification for the front-end wireless device, first establishing a wireless connection with the main AP, and then sending the wireless signals of the main AP,The TL-WR700N setting Bridge mode can also extend wireless coverage by first establishing a wireless connection with the main AP, then TL-WR700N sends its own wireless signals for client connections,

Q:What are the current situations for repeaters, hubs, modems, network cards, bridges, switches, routers, gateways to build networks?

They want to set up a large LANModem - router - hub - network cable - repeater - network PC - (network card)Hubs - bridges - bridges - switches - PC machines (network cards)Give it to me. So tired.
