What is the difference between 4 megabit fiber and 8 trillion fiber

The relationship between MB S (mega word second) and what is commonly referred to as MB S (byte second) is 8 times. 4m fiber, the actual ** speed is 10 8=. For 8m fiber, the actual ** speed is 8 8 = 1mb s.

I'm sweating, the upstairs is really... 4m is your broadband, theoretically** speed can have more than 400kb s, but the general control is** will never go to 400kb s generally around 300kb s, the lowest speed depends on how many of your **links, not particularly unpopular resources can go to 300kb s of 8m, it is a special fool people, I had a friend of telecommunications before, said that 8m was actually only 6m before, now it is actually only about 4m, basically it is difficult to reach the real speed of 8m. If you're going to get fiber, the speed will be slightly better than that.

It depends on what you use, the company generally uses such optical fiber, which is not much more expensive. It is recommended that 4m is definitely enough for family use, and if you are a company, you should get a 10m. Our company's 10m optical fiber, ** speed is only 500kb-600kb.

To put it bluntly, it's a difference in speed, and there is no other difference.

I have a friend who is a telecom customer service staff, of course, my home is installed is 4m, and then the speed is 1m, now it is 5m, of course, I also use telecom, because now it has entered the era of optical fiber, and now telecom broadband has recently launched a lot of preferential activities, according to different regions, the tariff is different, if it is an ordinary adsl according to the line conditions 1m can generally reach about 100kb, but the broadband of the optical fiber line 1m is generally about 115kb, if you need to play online games, It's still very good to handle 4m, and of course 8m is also very fast, just like now there is 100m fiber broadband in Chongqing, and personal use of 4m is already very good, if the computer memory is large, the configuration is good, and there is something wrong with the online game.

1 should be counted as an old user.

2. According to your terminal, the network speed is 50m or above, and it is an old user3, if you look for telecommunications, you can consider the old user: 100m2, 1440 this discount 4, combined with your own economic situation, consider it appropriately.

Consider the case where several terminals are running at the same time.

It is enough to choose 10m, which is enough to support the network speed of 1 computer and mobile phone.

50 megabytes of fiber is enough.

1. If you just go online, chat, and play games, the network of about 10m is enough.

Fiber optics do not specify how much megabit bandwidth.

It only provides high-speed bandwidth capabilities such as 10Mbps, 100Mbps, and 1000Mbps, while optical fiber broadband only transmits signals through optical fibers, and "optical modems" are installed at both ends of optical fibers for signal conversion. Optical fiber access can ensure that users can be provided with high-speed bandwidth of 10Mbps, 100Mbps, and 1000Mbps, which can be directly connected to ChinaNet backbone nodes. It is mainly suitable for high-speed access of commercial group users and intelligent community LAN, and high-speed interconnection with the Internet.

Three specific access methods can be provided to users.

Optical fiber is the most ideal one of a variety of transmission media in broadband network, which is characterized by large transmission capacity, transmission capacity, low loss, long relay distance, etc. Optical fiber transmission uses wavelength division multiplexing, that is, the data of multiple users in the cell is fused into high-speed signals by PON technology, and then the optical signals modulated to different wavelengths are transmitted in an optical fiber.

The main types of optical fibers:

Quartz optical fiber, quartz (glass) series optical fiber, with the characteristics of low consumption and broadband, has been widely used in cable TV and communication systems. Infrared fibers, as the working wavelength of quartz series optical fibers developed in the field of optical communication, can only be used for 2 m even if they are used for short transmission distances. Infrared fibers are mainly used for light energy transmission, e.g

Temperature metrology, thermal image transmission, laser scalpel medical, etc.

Composite optical fiber, characterized by the fact that the multi-component messy glass has a lower softening point than quartz glass and the refractive index difference between the core and the cladding is very large, and is mainly used in optical fiber endoscopes in medical business. Plastic-coated optical fiber, compared with quartz optical fiber, has the characteristics of thick core and high numerical aperture. Plastic-coated optical fiber is easy to combine with LED LED light source, and the loss is also small.

Therefore, plastic-coated fiber is very suitable for LAN and short-range communication. <>
