What is real fiber broadband?

OFweek Optical communication network news Broadband has become an essential part of our daily life, and it is also the basic construction of the national economy. However, we will not often have such a feeling that the advertising of major businesses is very attractive, ultra-low prices, ultra-high bandwidth. But more and more people find that after handling the so-called ultra-high bandwidth fiber optic broadband, the network speed is not really fast. Sometimes this broadband kind of bothers you, you know? In fact, this is not anything else, the so-called 20 trillion, 30 trillion, 50 trillion broadband in the market is not the real broadband, that is the people. Those who claim to be exclusive bandwidth are actually most of them are not exclusive, so how can you distinguish these situations and really use fiber optic broadband? Give us some common sense.
1, see the network access is light cat or network cable
Real optical fiber to the home to provide more than 100 megabits of bandwidth, which requires a direct connection to the home through optical fiber, in the user's home must also have a light cat, so that direct access to the Internet. The way of community LAN networking, it is to connect the network to a community, or a building, and form a local area network through the network cable to connect the shared network to each family. If the connection into your home is not a light cat but a network cable, it means that the entire community of users share the bandwidth that should be exclusive to one user. Why must a light cat be connected to the home? Because this optical cat is the transceiver device that converts optical Ethernet signals into other protocol signals. To your home directly to the light signal into the electrical signal, you can guarantee the bandwidth, otherwise not.
2, see whether the transmission material is copper wire or optical fiber
The cable that enters our home is also different, one is optical fiber, and the other is copper wire. Copper wire consists of a plurality of mutually insulated wires or conductors to form the cable core, with an external sealing sheath. Copper cables can't handle high bandwidth. Copper wire in fact, we all know that the inside is solid, is a copper wire, no matter how well done, can not support high bandwidth, and support high bandwidth is only the optical fiber. An optical fiber is a fiber made of glass or plastic. At present, the maximum bandwidth of access to the home through optical fiber can reach 100 megabits, and the downstream rate is about 11520-12800KB/S. The biggest difference between optical fiber and copper wire is that the optical fiber is actually hollow inside and can conduct light signals. There is a joke in the industry: "Optical fiber without copper, stolen useless." Because there is no copper in the optical fiber thief can not sell money, so it is useless for thieves, but it is useful for us, and the transmission speed of the optical fiber is not comparable to the copper cable.
3, often use software speed measurement to see whether it is stable
In the most basic way, we can make intuitive judgments by using common services and software, or use professional testing tools to measure speed.
In addition, the stability of bandwidth is also one of the methods to identify the true and false optical fibers. Most of the complaints of home broadband users often appear two types of problems, the first type is usually fast and slow holiday network speed (daytime network speed and night network speed is slow), the second type is the high network quality requirements of the game/online video, such as card, stop, break phenomenon, this situation is likely to be caused by the use of "fake broadband".
Therefore, the home is not really fiber broadband, can not guarantee the speed, do not be moved by publicity, to see what is the access method, how to access, to prevent falling into the consumption trap.
