Authoritative Answer: The difference between fiber optics and broadband ADSL.
This refers to the way broadband is accessed. There are a variety of broadband access methods to the user side, the most commonly used are ADSL, VDSL, FTTb+LAN, and optical fiber access, as well as wireless access and power supply modem access. The access mode is not directly related to the bandwidth requested, that is to say, the broadband of 2M can be achieved in either way, and the speed can reach 2M.
It's just that the path of implementation is different. It's like going from place to place, walking, taking a car, a plane, or a train. Because you are applying for 2M, no matter which way you use the access, you can meet your requirements.
If the network speed is increased to gigabit in the future, then ADSL, VDSL, FTTb+LAN, and wireless will not be able to meet the needs, and optical fiber can meet the requirements, but it is necessary to replace the equipment on both sides of the terminal and replace the 100 trillion device with 1000 megabytes.
Broadband refers to the network access mode with high transmission speed, and optical fiber is the transmission medium, not the same concept.
It can be understood that fiber optics are one of the ways to achieve broadband transmission.
Today's broadband is basically divided into fiber access and ADSL access.
ADSL currently has a maximum transmission capacity of only 10M.
Fiber optics have no such limitations.
Fiber optics and broadband are actually two different concepts.
Optical fiber transmits signals in the form of light pulses, and glass or plexiglass is used as the network transmission medium. It is a kind of transmission medium, just like twisted pairs, thick cables, thin cables, etc., but its transmission speed is much faster than ordinary media, which can reach more than gigabits per second.
And what we call broadband is the speed of our Internet access, and the rate of dial-up Internet access is from.
Ascended to. 56kbps, however, limited by ** line.
The quality of 56kbps should be average.
The limit of modem. If you want to get faster Internet speeds, you have to split the stream, so in recent years, a variety of broadband access services have emerged. So, what is broadband? In fact, there is no strict definition, it is generally based on the upper limit of the current dial-up Internet speed.
56kbps for the demarcation, will.
Access of 56kbps and below is called "narrowband", and access methods above it are classified as "broadband".

Ordinary broadband is generally made of copper wire, but the speed of using the wire to transmit network signals is very slow. In contrast, fiber optics transmit signals much faster. >>>More
