EDC Network Mining

1. On March 20, Lenovo held the 2018 mobile phone new proct launch in Beijing. Lenovo released the first blockchain smartphone Lenovo S5, two hundred yuan machines K5 and K5 play
in addition, Lenovo has also launched a super cheap smart watch watch watch 9, which is designed with conventional quartz watch and added intelligent sports function. The price is only 129 yuan, even cheaper than a conventional watch.

2. EDC is a cross chain polymerized currency under the defi ecology. From uniswap to several centralized exchanges, airdrop, audit, mining and more ecology will continue to advance. The holding address is over 10000, and the market value will grow steadily!

EDC = every day carry things with you every day, such as mobile phones, watches, bracelets, wallets, knives, flashlights and so on. Some people even carry binoculars

Existentialism: Existentialism, a proct of the nuclear threat era, always believes that world war will break out and mankind will perish, and then we will have to rely on ourselves to survive in the desolate land. Most of them are cynical and live alone far away from the crowd. They live in the most difficult way and exercise themselves and their family and friends. They also store a large number of weapons, ammunition and medical supplies, and dig bunkers to welcome the end of the world

in addition, EDC is also a French clothing brand, EDC is a derivative brand of esprit, and what she pursues is a kind of personality and self-expression attitude towards life. She strives to show sports, personality and unrestrained life fun, creating a new style of youth and popularity for 18-25-year-old people

EDC also refers to the expected date of delivery, which is not the exact date of delivery. Scientists have counted that only about 5% of women give birth on the day of the expected date of delivery

EDC means electronic dispersion compensation, which refers to the way to compensate optical dispersion in the field of electricity. It is the basis of OIF and IEEE802.3 new standards

when the signal rate of optical fiber transmission reaches 10Gbps, the problem of dispersion interference appears, and with the increase of the symbol rate of data transmission, the problem becomes more serious, and becomes the biggest obstacle to improve the rate. EDC is designed to solve the dispersion interference, in order to rece the optical signal damage caused by dispersion

extended data

for the implementation of electronic dispersion compensation, the most common architecture is based on the combination of feedforward equalizer (FFE) and / or decision feedback equalizer (DFE), which adopts more complex signal conditioning than continuous time filter. FFE and DFE are usually multi tap architectures, and they are effective methods to compensate inter symbol interference

when there is only a single unit interval interference, FFE / DFE only needs to determine whether a symbol has been extended to the adjacent symbol, and then add or subtract the symbol accordingly. When there is more than one unit interval of interference, it is not only a single symbol extending to adjacent symbols, each symbol can be distorted by several adjacent symbols

EDC means electronic dispersion compensation. It is the basis of OIF and IEEE802.3 new standards

There are three types of dispersion: chromatic dispersion, mode dispersion and polarization mode dispersion. When the signal rate of optical fiber transmission reaches 10Gbps, the problem of dispersion interference appears, and with the increase of the symbol rate of data transmission, the problem becomes more serious, and becomes the biggest obstacle to improve the rate

EDC is used to solve the problem of dispersion interference to rece the signal damage caused by dispersion. Using EDC technology, the connection distance of 10Gbps SONET single-mode optical fiber can reach 145 km (the worse optical fiber can reach 120 km), and OC-48 (2488.32 Mbit / s) can be upgraded seamlessly

extended data:

in order to extend the transmission distance of optical signal, we mainly start from recing dispersion and loss or amplifying optical signal. It is proved that the transmission dispersion of optical signal at 1310nm is the minimum, and the transmission loss at 1550nm is the minimum. When the optical amplifier appears, the traditional transmission repeater has been replaced, and the problem of long-distance transmission loss has to be solved

But fiber amplifier can not solve the problem of dispersion. EDC dispersion compensator is a kind of passive equipment, which is used to repair the optical signal distorted by dispersion in communication transmission system. It is widely used in 20km-145km long-distance transmission system and WDM transmission system

EDC dispersion compensator has slope compensation function, which can compensate the dispersion slope of standard single-mode fiber (G.652) in C-band and optimize the resial dispersion of the system. Based on mature and reliable optical fiber technology, it can improve the performance of optical transmission system

8. No, 1. The service objects of CMCC and cmcc-e are different. The former is for all users, while the latter only provides network services for the campus area. 2. CMCC is a common type of wireless broadband. In the area covered by CMCC, Internet services can be accessed through laptops, mobile phones and other terminals with WLAN functions to carry out information acquisition, entertainment or mobile public operation. 3. Cmcc-e is a wireless broadband service in Colleges and universities, which can only enjoy high-speed Internet access service in many campus hot spots.

10. The router is abnormal. Reset the key for the first time. At this time, the router has been restored to the factory default value and needs to be reset again

first of all, keep the front-end equipment (optical cat) intact and the network unblocked

② after pressing the reset button of the router, wait until all the indicators are on together, indicating that the reset is successful

③ enter the IP address, user name and password in the browser address bar (there is a prompt on the back of the router)

④ after following the router setup wizard, you can access the Internet normally
