Q:How to relay submarine fiber optic cables?

Submarine optical cable without relay and relay submarine fiber optic cable. Here, repeaters are electronic devices at the bottom of the sea, not electronic optical repeaters used in previous undersea cables (working at 1300nm wavelengths). The current submarine optical cable system works at the 1500nm window using an optical amplifier. However, if the fiber amplifier is sufficient to obtain electrical power at the end of the fiber optic cable, then such a system should also be considered a relay. Repeaters can also refer to a cylindrical containing light amplifier and pump source for light sealed containers, but if the pump source of optical amplifier is located on the shore of the laser diode, optical amplifier that is installed on the seabed is not a repeater. Based on these definitions, a relay free submarine fiber optic cable is developed

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

The connection between the wireless AP and the normal network is the converter, which can be purchased at Taobao. Also, the AP cable on the receiver side is connected to the wireless WIFI (wireless router).If the distance is no more than 50 meters, you can buy an enhanced version of the wireless router.

Q:Do wireless Wifi repeaters have portable?

For example, a mobile phone search outside a WIFI, because the signal is weak, unstable in the room, in the balcony or outside the window, but the signal is strong enough. Just install a relay on the balcony, you can use the WIFI stable in the room.Of course, you need to know the password for WIFI.

Q:Is the repeater located next to the router?

Relay next to the router, equivalent to no relay and routers, you can use the cable network, you can also use the wireless connection, but with the cable link will be better

Q:Do you need the same brand as the WiFi router using the WiFi repeater?

If you buy a new router, it is strongly recommended to buy the same brand.

Q:What is the function of the repeater in the automatic alarm?

Line repeater, which can be powered by an external power supply, preferably with batteries. Generally not connected from the host.

Q:What is the difference between a router, a hub, a switch, and a repeater?

Hubs:HUB is a basic device in the data communication system. It is the same as the transmission medium such as twisted pair. It is a hardware device without any software support or very little management software. 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.

Q:Speed issues on wireless repeaters

The work principle is different. The A model should be the received signal, which will be transmitted with a new name after processing. (the frequency band may also change). For the main route, the A is equivalent to a terminal (such as a computer or a cell phone).

Q:About the use of RS485 repeaters?

Signals at both ends should be isolated and amplified, after all, bidirectional transmission. 4., I have tried 2 kinds of connection, the effect is similar, my network from the station more and interference, should be no problem. But habits make progress.

Q:What does wireless relay mode mean in routers?

Set up a wireless router (1), computer connected to a wireless router: a wireless network is enabled by default wireless router, and the password is not set, so the computer's IP address, can be connected to the router with the computer through the wireless way. Scan the wireless network with the computer's wireless network card, and then click the connection when you find the wireless network name of the router. (2) login TL-WR700N management interface: enter "192.168.1.1" in the browser, enter the login account number and password admin/admin, open the management interface of the router. (3): run the setup wizard, click on the left side of the "Wizard" -- > "next". (4) the work mode selection: select the "Repeater mode" -- > "next" interface settings in the work mode, (5), wireless settings: click "scan", find the higher the router SSID (recorded in the first step, and then click "connect)". Set with the router TL-WR941N the same encryption and password - > "next" (6), click the "reset", TL-WR700N will automatically restart, restart after completion, just set to go.
