I want to install telecom broadband, but I already have a mobile cat at home, and I don t know if I

No, you can't. Telecom cats nowadays are all dedicated.

Now there are three access modes for telecom broadband, the first is the access mode of ** line, which is pppoe dial-up.

The second is digital access, which uses network cables and PPPOE dial-up (this number means that they convert the optical fiber digital signal in the corridor, and it is no longer a long-distance transmission like a telecommunications line, which will be much faster.) Numbers are just the type of way they do their transmissions).

The third type is optical fiber access users. It is directly connected to the optical fiber at your home to the telecom optical modem for conversion, which is very fast. Then this cat also integrates the ** output port, so it is very dedicated.

Conclusion: Other cats can only be used in the first access method of telecommunications. (Applicable to the Old Town).

The cat is also called the debugging demodulator, which is a signal medium conversion device, first of all, you have to determine what medium and signal transmission mode are used in the mobile and telecom home lines, in order to determine whether the cat is the same.

Telecom low-speed networks are generally first-line transmission, ordinary**, ISDN narrowband, ADSL broadband, these are first-line transmission, but the cats used are different; There are also high-speed broadband fiber optic cats that are different.

In some places, ADSL lines are used for transmission, in some places, IP signals are directly used for network cables, and high-speed broadband fiber optic modems are also used.

By confirming what line and medium is used to transmit the signal, the type of cat can be determined.

It's the router that moves it, and it seems that it can be used universally, but the telecom cat also needs to be used.

The broadband installed with telecommunications is equipped with cats for you, and when the network is withdrawn, it will be returned to them. Don't use your own.

Telecom broadband Telecom business hall will send a cat for free, and the mobile one cannot be used in telecommunications.

China Mobile Fiber Modem and China Telecom Fiber Modem cannot be used together.

Telecom fiber optic networks are divided into GPON and EPON, and the same network may also have compatibility problems, and OLT and ONU must be used together.

The so-called optical fiber modem refers to a transceiver device that converts optical ethernet signals into signals of other protocols. Routing modem is a common name for optical modem routing, which has the functions of modem and routing.

Mobile optical modem, also known as single-port optical end router, is a product designed for special user environments, and is a single E1 or single or single 10BaseT point-to-point optical transmission terminal equipment that uses a pair of optical fibers. The equipment is used as a relay transmission equipment for the local network, and is suitable for optical fiber terminal transmission equipment of base stations and leased line equipment.

Yes, it is generally sent together with the broadband service and returned when the business is completed.

The cost of optical fiber installation is high, the installation cost of major operators ranges from 200-500 yuan, China Telecom has a refundable one, China Mobile and Great Wall Broadband are not refundable, and the others are unknown.

Optical fiber is connected to blue, it should be noted that some of the cat's optical fiber interface is at the bottom, as shown in the figure below, it should be noted that the interface of the optical fiber line is not the same as the general network cable interface, because it is generally done directly by the installation master, how to do it first, there is a need to supplement in the message area.

But it is better to choose the operator to provide the fiber optic modem.

1. Fiber-to-the-home users need to connect the optical fiber to the modem device before they can use it.

2. Optical fiber broadband is to modulate the electrical signal into an optical signal through the equipment in the operator's computer room, and transmit it to the user through the optical fiber. To access the Internet through optical fiber, users need to use the optical modem equipment that is matched with the equipment in the operator's computer room, convert the optical signal into an electrical signal that can be used by the user's computer and other equipment, and connect the user's device to the Internet through network cables.

3. Parameters such as optical ports, optical ports, and optical wavelengths at both ends of the optical fiber should correspond to the equipment in the operator's equipment room before they can be used. Therefore, you should choose the one provided by the operator.
