What s the deal with the legendary fiber optics? How many megabytes can be distinguished?

Fiber optics themselves are gigabit indiscriminate.

The gigabit fiber we call in our life is actually the optical film block (that is, the optical fiber port).

First of all, single-mode optical cable is not divided into gigabit or 10 gigabit, single-mode wiring is gigabit rate or 10 gigabit mainly depends on the equipment it uses, under normal circumstances, single-mode optical cable through the support of equipment, working at 1550 m wavelength optical single-mode optical cable can support 10 gigabit (10Gbps) at least 60 kilometers.

Multimode fiber optic cables. According to the different transmission rates, it is divided into OM1, OM2, OM3, and OM4. The core diameter of OM1 is 50 m from OM2 to OM4.

The OM1 fiber optic cable supports gigabit distances of 300 and 550 meters at 850 m wavelength and 1300 m wavelength, respectively. It is also possible to support 10 mega at a distance of 100 meters.

Generally, families are 50m, 100m, 200m broadband, depending on the actual area of each family. The bandwidth of 100M in an ordinary family is completely sufficient, even if you watch ** at the same time, watch live broadcasts, and play games, you won't feel stuck, no matter how large the bandwidth is, it is a waste.

If you are still not sure how much megabit broadband you need at home, you can go to the business hall to consult the relevant salesman, and he will recommend the right one for you according to the size of your house and the specific use scenario.

Distinguish the difference between home bandwidth and leased line.

1. Household bandwidth is generally shared, and leased lines are dedicated bandwidth. So during peak hours, sometimes you feel like the internet is fast.

Relatively slow. 2. The uplink of the household bandwidth is rate-limited, and there is no speed limit for the dedicated line, and the uplink and downlink speed is the same. There is no need to upload a lot of data, and the experience is indistinguishable.

Third, some sensitive ports are disabled for home bandwidth, such as port 80.

If you don't do service equipment, it won't have much impact.

Let's talk about networking again.

1. Fiber-to-the-home.

At present, the networking is basically the same, and only fiber-to-the-home can achieve real 100 megabit bandwidth. The maximum load of the network cable can theoretically be 100 megabits, but the actual loss of too many megabytes has reached the limit.

2. Fiber-to-the-floor.

Fiber-to-the-building, network cable to the home. The maximum speed of the network cable has been mentioned above, which can be referred to.

Hello dear, here is a way to find out how to know how much is the trillion of your own optical fiber for reference: 1. Enter the adsl modem, you can see the lead, under the situation of connecting to the network, enter the adsl modem, and see the downlink size of the network connection shows that 2048 is 2m; 1024 is 1m; 2. Look at the ** speed of the normal time, for example, when the Thunderbolt** movie, if the speed shows about 200kbps, it is 2m, and the display of 100kbps is 1m, the flow = bandwidth * 1024 83, check the paper of the monthly procedures at that time, and the service will be written on the paper; 4. If it is telecommunications, Netcom, Tietong, etc., call customer service**, as long as the account number and password are reported, the customer service lady will sue the chain Hongcheng; 5. Check on the Internet, log in to the local broadband service company, log in to the local telecom, and log in to the railway, and enter your broadband account and password on the **, and you can also query the type of broadband.

Optical fiber does not specify how much megabit bandwidth, optical fiber only provides high-speed bandwidth capabilities such as 10Mbps, 100Mbps, and 1000Mbps.

Optical fiber communication is based on the above principle, because the propagation speed of light in different substances is different, so when light is shot from one substance to another, refraction and reflection will occur at the interface of the two substances.

Moreover, the angle of the refracted light will change with the angle of the incident light. When the angle of the incident light reaches or exceeds a certain angle, the refracted light disappears and all the incident light is reflected back, which is the total reflection of light. Different substances have different angles of refraction of light of the same wavelength (i.e., different substances have different refractive indexes of light), and the same substances have different angles of refraction of light of different wavelengths.
