How to identify optical fiber and broadband, and how to check whether your broadband is optical fibe

Optical fibers are used to communicate, and optical fibers are generally wrapped in a lot of things, so the appearance of optical fibers is like a little finger or a small size of black very hard wire, there are also other shapes, it is difficult to say.

ADSL is used with a computer cable, ** cable is connected to the modem, and then a network cable is connected to the router or computer, and the router is connected to the computer or switch, and the switch is connected to the computer.

If it is fiber, there should be at least three boxes, and ADSL can have at least one cat, which is the modem.

As long as you see whether you use ** line is ADSL, optical fiber is generally a few thousand pieces a month, I don't think you will have so many meters.

Generally, when we sign a broadband contract, the broadband identification code will be clearly marked on the contract.

Hello, I'm glad to answer for you, the broadband identification code is the authentication code, and the broadband identification code is different for each user in the location of the network authentication of the optical modem; The broadband password is given by the operator, and it is provided when the broadband is opened, and the broadband password can be modified if it is forgotten.

The broadband identification code, also known as the authentication code or LOID, is different from the broadband account number and password, it is the location that needs to be configured in the network authentication in the modem, and each user is different. The telecommunications company gives each user a registration code.

The LOID code is different from the broadband account number and password, it is the location that needs to be configured for network authentication in the modem, and each user is different. It is used for handshake authentication with the central office device, and only when the identification code matches the central office device, the optical modem can communicate with the central office normally, thus establishing a channel. If the LOID is misconfigured or missing, usually the PON light of the modem does not light up or flashes.

How else can I help you?

Here's how to identify them:

1. ADSL mode is ** wire access, using ADSL cat, and the cable connector is RJ11 crystal head (only two core ** wires, and the inner core is copper wire).

2. The network cable enters the home into two ways: metropolitan area network broadband and optical fiber into the building + LAN mode, and the final access user has no cat, only one network cable, and the connector is the ordinary network cable RJ45 crystal head.

3. The optical modem must be used for the exclusive broadband of optical fiber, and the connector is a blue square fiber connector (FC head), which must be connected to the optical modem.

1. One is propagated by cables through electricity, and the other is propagated by optical cables, the propagation speed of light is faster than electricity, and the bandwidth of optical fiber broadband is also larger than that of ordinary broadband, and the speed is far greater than that of ordinary broadband.

2. Fiber optics and broadband are actually two different concepts. Optical fiber transmits signals in the form of light pulses, and uses blue glass or plexiglass as the network transmission medium.

3. Optical fiber is a 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 one gigabit per second.

4. There is no very strict definition of broadband, which is generally demarcated by the upper limit of the current dial-up Internet rate of 56kbps, and the access of 56kbps and below is called "narrowband", and the access mode above it is classified as broadband.

5. In a word, broadband refers to the network access mode with high transmission speed, and optical fiber is the transmission medium, not the same concept.
