- 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: RS485 photoelectric isolation relay
- RS-485 signal after transmission distance or load device with a certain number of signal strength, will have the corresponding attenuation when the signal attenuation to a certain extent, RS-485 interface chip can detect the corresponding signal, resulting in communication failure.
- Q: Are signal amplifiers or repeaters powered?
- You can consider POE power supply equipment, equipment is only one cable, the power cable from the equipment, that is to say, the power adapter can be placed in the indoor equipment, except a cable, not what other needs. Choose which kind of equipment specific, you can go to the market to choose, see, remember to say with the seller, must POE power supply on the line.PS, I think god horse relay not relay, in the middle of a switch is not solved (of course, also must be the kind of POE power supply).
- Q: What are the functions and principles of repeaters?
- Effect: the general relay has 2 or 4 pairs of normally open normally closed contact, when the coil operating normally open, normally closed variable variable normally closed, normally open, if, at this time, normally open normally closed contact is connected in the control circuit, a closed or to disconnect the other line function.
- Q: How can wireless AP (trunking) be used to connect wireless routers that shut down SSID broadcasts?
- Wireless networks with SSID broadcasts have been closed, that is, wireless network names are hidden. Wireless Internet devices are unable to find the wireless network.
- Q: Relay function of wireless router
- This setting is complete, you can click on the router interface working state, the normal connection is successful, as shown in the Internet mode is displayed, the relay mode, WAN port state will show the acquisition signal.
- Q: What's the 485 repeater for?
- 485 the use of repeaters:For point to point and point to multipoint communication, industrial control automation, traffic control automation, smart card, access control, attendance, meal selling system, industrial distribution distribution system, CCTV, security systems, POS systems, building automation systems, self-service bank system.
- Q: About repeaters and common twisted pair problems
- The function of the repeater is to regenerate and transmit the received signal so as to increase the distance of signal transmission. It is the simplest network interconnection device that connects two or more network segments of the same network.
- Q: What brand of network repeaters is best?
- Network repeaters and wireless routers have the same brand names.
- 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.
