What is a mobile broadband fiber modem and what does a mobile optical modem mean?

In general, it should be a cuboid. Optical fiber converters, the network cables used in broadband are all optical fibers, the structure is different, the equipment can not be used, only optical modem.

To convert, the socket that comes out is the socket of an ordinary network cable, but you better need the gigabit level.

The working principle of the mobile modem is:

A baseband modem consists of transmitting, receiving, controlling, interface, control panel, and power supply. Data terminal equipment in binary.

The data sent is provided in the form of a serial signal, which is converted into an internal logic level through the interface and sent to the transmitting part, and the signal required by the line is modulated by the modulation circuit and sent to the line. The receiving part receives the signal from the line, which is filtered.

Reverse modulation, level shifting, and then revert to a digital signal.

Feed into the digital terminal device. Optical modem.

It is a device similar to a baseband modem, which is different from a baseband modem in that it is connected to an optical fiber dedicated line and an optical signal.

Fiber optic cats. The scientific name is Class A ONU, which is now a more advanced network access method, which requires mobile background data management personnel to open it on the spot, and configure data in your optical modem, this optical modem can only be used on your line, and other optical modems can not be used, and yours cannot be used in other places.

A mobile modem is an optical modem, and an optical modem is also known as a single-port optical transceiver.

It is a three-piece optical fiber transmission equipment developed for special user environments. The device adopts a large-scale integrated chip, simple circuit, low power consumption, high reliability, complete alarm status indication and perfect network management function.

Now optical modems basically come with their own wifi function, and generally family houses can be used for about 30 square meters, but we generally recommend not using the wifi function that comes with optical modems, for the following reasons.

The wireless wifi that comes with the optical modem is actually an auxiliary function,Let him install broadband and no router friends temporarily use,It is not the main function of the optical modem,The experience is very poor in the functionality and stability of the router,It is estimated that it is okay to use it at the beginning,But after a period of time, click on the stuck,The experience is extremely poor,And the biggest drawback of the optical modemwifi is that there is a maximum number of connections limit,At most, there are 4-5 devices at the same time**。

Now the broadband speed exceeds 100M, you need to use a gigabit wireless router, and the wifi must support two frequency bands and 5G. The optical modem given by the operator usually only supports the frequency band. That is to say, if it is 200 megabyte broadband, the maximum speed of the mobile phone connected to the optical modem wifi is only about 70Mbps, and the actual speed is about 30Mbps.

In addition, the total bandwidth of wifi is shared, if there are 3 mobile phones at home, then the mobile phone is connected to the optical modem wifi, and the speed will be very slow. In addition, the WiFi function of the optical modem is also more troublesome to change the password, and it does not support APP management.

There are more wifi devices at home, and watching on the Internet at the same time may cause Caton, because it does not support multiple devices to send and receive at the same time, that is, the wifi of the optical modem is sent to the wifi user in turn when sending data. It is recommended that you still have a router!

<> "There is no mobile logo at hand, but these optical modems are basically the same, but the printed logos are different, the networks of these operators are the same, the EPON or GPON method used, and the optical modems at the end are basically the same, and most of the choices are Huawei or ZTE.

If it's this problem, it's the optical modem used to use the optical cable to enter the home, not the mobile optical modem. It's the same as any other normal light cat. Hope to adopt.

The broadbanded cat looks like a rectangular box.

A finger-like broadband cat will be placed in the fiber optic interface box, and this cat looks like a rectangular box, with many interfaces on the box, and there is also a power cord connected to the power supply.

The role of the broadband cat:

1. Generally speaking, the optical modem is a device responsible for photoelectric conversion. Since there are two technical modes of fiber broadband, one is EPON access and the other is GPON access; Optical modems are also divided into two types: EPON optical modems and GPON optical modems, which need to be paid attention to.

2. From the interface of the optical modem, the optical modem usually has an optical fiber interface, 2-4 LAN ports, and a gigabit optical modem will have at least 1 gigabit interface.

3. In addition, the modem will also be equipped with 1-2 ** interfaces as standard. From this point of view, the modem is a comprehensive network access device, and it is very professional.

4. For this reason, optical modems can usually only be purchased from operators. From a purely technical point of view, as long as the tribrium is equipped with the same access technology, the optical modem is universal.

5. For example, EPON optical modems can be used universally regardless of operators; Similarly, GPON does not distinguish between carriers and can be universal. In the actual cavity, the optical modems of the three operators are customized. <>
