The fibre-optic broadband of telecommunications must have been heard, but there is little real fear of what fibre-optics are. Fibrous broadband is a relatively new type of broadband, and fibre-optic broadband and conventional, traditional broadband data are transmitted differently. Traditional broadband is transmitted by telecommunications, whereas fibre-optic broadband is transmitted by light signals. The following mini-editor shows the price of telecommunications fibre and the difference between fibre-optic broadband and broadband。
Price of telecommunications fibre-optics
4m telecommunications fibre, with a single broadband 4m package at a price of 720 yuan/year. (price source network, for information purposes only. I'm not sure
10m telecommunications fibre-optics, with a single broadband of 10m at a price of 960 yuan/year. (price source network. For information purposes only. I'm not sure
20m telecommunications fibre-optic, with a single broadband of 20m at a price of 1,800 yuan/year. (price source network, for information purposes only. I'm not sure
The difference between fibre-optic broadband and broadband
Broadband has multiple modes of access to users, most commonly adsl, vdsl, fttb+lan, fibre-optic access, wireless access and electrical cat access, among others. The mode of access is not directly related to the bandwidth requested, i. E. The broadband required to apply for 2m can be achieved in either way at a speed of 2m. It's just a different path. It's like walking, taking a car, flying, taking a train from one place to another. Because you're applying for access in any way you want. If the speed of the net is raised to a gigabytes in the future, then neither adsl, vdsl, fttb+lan, nor wireless will be able to meet the requirements, and fibre-optics will simply need to replace the equipment at the two terminals with 100 gigabytes of equipment。
Broadband refers to high transmission speed network access, and fibre-optics are transmission media, not the same concept。
It is understood that fibre-optics is one of the ways to achieve broadband transmission。
Now broadband is basically spectro-optic and adsl is connected, and adsl currently has a maximum of 10 m
Optical fibre and broadband are actually two different concepts
Fibres transmit signals in the form of light pulses, using glass or organic glass as a network transfer medium. It's a transmission medium, like a double winch, a rough cable, a thin cable, etc., but he's moving much faster than the normal medium and can reach more than a gigabyte per second。
And what we're talking about broadband is how fast we're going to go online, and the dial-up rate has risen from 14. 4 kbps to 56 kbps, but it's limited to the quality of the telephone line, and 56 kbps is supposed to be the limit of normal modem. Access to the internet at a much faster pace would have to cut other streams, and thus a variety of broadband access services have emerged in recent years. So, what is broadband? There is no strict definition of broadband. It is generally divided by the current dial-up rate of 56 kbps, which classifies 56 kbps and their access below as “close bands” and above as “broadband”。
Telecommunications fibre or broadband
1. Transmission bandwidth and high communication capacity。
The optical wave frequency is 5x1014 mhz, and the fibre-optic bandwidth is thousands of mhz or even higher。
2. Low signal losses。
Current practical fibre-optics use highly pure sio2 materials, which can be reduced to 0. 2 db/km near the theoretical limit, near a light wavelength of 1550 nm. Therefore, it can be very far from relay。
3. Free from electromagnetic waves。
As fibre-optics are non-metal media materials, they are not subject to electromagnetic waves。
4. Line size, light weight。
Because the fibre-optic diameter is small, it's only about 0. 1 mm, so when it's made, the diameter is smaller than the cable, and the weight is lighter。
5. The delay in access to the network is within 10 ms and, in the case of telephone lines, within 50 ms。
In summary, fibre-optic broadband can be used faster, with lower wear and tear, longer usage and lower delay in the network, and the selection of fibre-optics is recommended。
The development history of fibre-optic broadband has been relatively short, but the technical quality of fibre-optic broadband is indeed very good for use, and many newly constructed residential areas are now beginning to use fibre-optic broadband. The fibre-optic broadband can provide a large amount of transmission, and the quality of the transmission is very good, and if you want to use telecommunications fibre, move quickly。
