Three tricks to teach you to identify true fiber broadband

Broadband is already an indispensable necessity for everyone's daily life, and it is also the infrastructure of the national economy. But do you often feel this way? The ads from major businesses are very attractive, with ultra-low prices and ultra-high bandwidth. However, more and more people find that after applying the so-called ultra-high bandwidth optical fiber broadband, the network speed is not really fast, and sometimes this broadband is quite annoying. In fact, the so-called 20 MB, 30 MB, and 50 MB broadband on the market are not real broadband, they are the people of Mongolia. Most of the so-called exclusive bandwidth is actually not exclusive, so how can you distinguish these situations and really use fiber broadband? Let everyone know some common sense.

1. See if the network access is optical cat or network cable

Real fiber to the home can provide more than 100 megabits of bandwidth, which requires direct connection to the home through the fiber, and there must be a light cat in the user's home, so as to directly access the Internet. The way of community LAN networking is to connect the network to a community or a building, and form a local area network to connect the shared network to each family through a network cable. If you connect to your home not with a light cat but with a network cable, it means that users in the entire community share the bandwidth that should be used by a single user. Why must a light cat be connected to the home? Because this optical cat is a transceiver device that converts optical Ethernet signals into other protocol signals. When you go to your home and directly convert the optical signal into an electrical signal, you can guarantee the bandwidth, otherwise it is not.

Second, look at the transmission material is copper wire or fiber

The network cables that enter our home are also different, one is optical fiber and the other is copper wire. The copper wire is composed of a plurality of mutually insulated wires or conductors to form a cable core, and has a sealed jacket on the outside. Copper cables cannot bear high bandwidth. In fact, we all know that copper wire is solid inside. It is a copper wire. No matter how well done, it can not support high bandwidth, and only high-bandwidth supports optical fiber. 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 trillion, and the downlink rate is about 11520-12800KB / S. The biggest difference between optical fiber and copper wire is that the optical fiber is actually hollow and can transmit optical signals. There is a joke in the industry: "Optical fiber has no copper, it is useless to steal." Because there is no copper thief in the optical fiber, it is useless for thieves, but it is of great use to us. The transmission speed of optical fiber cannot be compared with copper cables.

Three, often use software to measure speed to see if it is stable

The most basic way, we can use common business and software to make intuitive judgments, or use professional testing tools to measure speed.

In addition, the stability of the bandwidth is also one of the methods for identifying true and false optical fibers. Most of the complaints of users' home broadband often have two types of problems. The first type is usually fast network speed and the holiday speed is slow (the network speed is fast during the day and the network speed is slow at night), and the second type is games that require high network quality. / Online video, etc. will appear stuck, broken, broken phenomenon, this situation is likely to be caused by the use of "fake broadband".

Therefore, whether the home is really fiber optic broadband, can you guarantee the speed, do not be moved by the publicity, to see exactly what access method, how to access, to prevent falling into the consumer trap.
