Anonymous users2024-02-06Look at the light cat. There are two ways to do it, one is to look at the mark next to the network interface of the optical modem; One is to check the optical modem manual. Let's talk about each of them separately.
1. Optical modem network interface typeOptical modem, also known as optical modem.
After the optical cable enters the home, it must first be connected to the optical modem, and then the network interface of the optical modem will be connected to the wireless router.
Computer or IPTV network set-top box, etc. Earlier network bandwidth.
It is generally 20m or 50m, so most of the optical modems are 100 megabit optical modems.
Later, the broadband speed increase, the starting bandwidth is 100m, and then to 200m, 300m, at this time, you must use a gigabit optical modem, so how to see whether the optical modem is gigabit or 100 megabit? We can look at the markings next to the network interfaces of the optical modem, for example, the optical modem I am using now is tewa-600ngm, and there are only two network interfaces, one is gigabit and one is 100 gigabit. The gigabit interface is used to access the Internet, and the 100 Gigabit interface is connected to IPTV network TV.
Therefore, this optical modem is a gigabit optical modem.
2. The method of judging whether the optical modem is gigabit or 100 gigabit is like the second one above is the gigabit optical modem, although there is only one gigabit network port, in addition to the above optical modem, mark the gigabit or 100 gigabit next to the network interface, let's take a look at what other ways to judge. First, you can be more optical cat models, search for optical cat manuals on the Internet, and of course, go to the official website of optical cat manufacturers to inquire the most authoritative; Second, find a computer with a Gigabit network card, connect the modem to the computer with a network cable, and check the network connection status of the computer after the modem is powered on. As shown in the figure below, check the network connection, right-click, click Status, check the connection rate, if it is 1G, it is not Gigabit, otherwise it is 100 Gigabit.
To sum up, it is necessary to see whether the modem is gigabit or 100 gigabit, first, check whether the network interface of the optical modem is marked; Second, consult official information or manuals; Third, connect with the Gigabit network card computer, check the connection speed, and display 1G for Gigabit.
The above is based on my experience, analysis, shortcomings, criticism and correction are welcome.

Anonymous users2024-01-31The Gigabit Ethernet port on the optical modem is used to connect to a router or a computer, and the 100 Gigabit port is used to connect to a set-top box to watch IPTV. The gigabit port is the 10 100 1000m adaptive Ethernet port, and the 100 gigabit port is the 10 100m adaptive Ethernet port.
At present, operators provide broadband and IPTV, and provide both services through a fiber connection modem to provide both services.
The Gigabit Ethernet port can provide a maximum networking speed of 1000M, and can provide a speed of up to 1000 8=125MB s. The 100 Gigabit Ethernet port can provide a maximum speed of 100 8= through a maximum networking speed of 100m.
In our current home broadband networking mode, the core device that provides the network to the home is the router.
The difference between 100 Gigabit and Gigabit optical modems.
Optical modems can be divided into several categories according to port types, one is the full 100 Gigabit port, which we call 100 Gigabit optical modems. One is the full gigabit port, which we call the gigabit optical modem. The first type is the optical modem with both 100 Gigabit and Gigabit ports.
There is nothing to discuss about the first two types of optical cats, but we will mainly talk about the third type of optical cats.
The optical modem can transmit three types of services: network, IPTV**, and voice, and the network and IPTV** use the RJ45 interface, which is what we often call the network interface, and the voice uses the RJ11 interface. Gigabit ports and 100 Gigabit ports are identified separately, mainly to separate the network from IPTV** services, Gigabit ports are used for networks, and 100 Gigabit ports are used for IPTV** services (of course, there is no absolute, and it is not impossible to use 100 Gigabit ports to connect to the network, but it is not reasonable from the perspective of business).
Finally, let's talk about the difference between the operator's IPTV** service and the network set-top box. The operator's IPTV** service does not occupy your network bandwidth, has its own independent line, and the 100 Gigabit port is enough to use. Through the network set-top box, you need to occupy your network bandwidth, and you need to use the same computer, tablet, mobile phone and other devices to grab the bandwidth.
Operator IPTV** is equivalent to intranet access, and it also has certain advantages over network set-top boxes in terms of speed. As for the comparison of content and resources between the two, there is no clear answer to this, and it can only depend on the policy and development degree of local operators. <>
The idea of raising children to prevent old age is very utilitarian, if it is purely for the sake of their old age, it is better to make money while they are young, and having children is not because of raising children to prevent old age or because others get married and have children, and it is time for them to get married and have children, and children should be the crystallization of the love of two people.
At the heart of Buddhism is faith. Although Buddhism is known as the "religion of philosophy", it is a religion after all, and faith is undoubtedly its core content, and the belief that people can become enlightened and become Buddhas constitutes the essential characteristics of Buddhism. However, the important difference between Buddhism and other religions in general is that its liberation is "wisdom liberation," and Buddhism revolves around the fundamental goal of attaining wisdom through the practice of Buddhism. >>>More
When I was in high school, I watched their shows, songs, or something, and it felt average, but after I went to college, I felt that they were very naïve, too boring, and I felt that Korean singers were very fake and pretentious, and the women were all squirming and pretending to be very annoying, but I liked to watch them when I was in high school Later, I found that these people have no level at all, maybe they are older and a little more mature, South Korea's ** is very single, there is no innovation, singers pay too much attention to packaging, and the audience of artists like TVXQ is generally 12 19-year-old people, charter ang is important, but it's too much, you get tired of watching it for a while, there is no inner content, and their country is the same, including**also, and the national conditions are very consistent Always want to prove to the world that he is gorgeous, sophisticated, but there is no soul in it! After listening to it for a long time, you will find out that TVXQ is very popular in China and South Korea, and I believe that the relatives who speak here are all under the age of 20, because I show that the girls below high school around me are fanatically chasing them, and almost no one in the circle of my college classmates is interested in them. The simplification of South Korea has lasted for four or five years, and the record industry has begun to decline So TVXQ is going to China to go to Japan to make money, South Korea** is of course stronger than China, but compared with Japan, it is not just a little worse With a group of TVXQ's strength, the development in Japan will not be too good, because Japan's local boy groups are excellent, but it is a fact that the hype is very fierce I like Japan very much, because it is diverse, fresh and natural The one-person packaging industry is very appropriate The premise of BOA's successful development in Japan is that her strength should not be underestimated, and she is completely integrated into the Japanese market, and basically gives up the development of South Korea, only in this way can she compete for a place in the fiercely competitive and exclusive market of Japan TVXQ is basically the development of China, Japan and South Korea, and Li Xiuman's appetite is inevitably too great, you must know that there are few good things in the world that have the best of both worlds, let alone three countries What was said when the hype was very good, actual >>>More
