Hub The hub works on the first layer of OSI, and the data packets sent to the hub will be broadcast to all ports. The hub is directly physically connected to the network card of each device, so there is a lower risk of connection loss, because the hub is a...
Hello, everyone! As a supplement to the ONT basic knowledge, I begin to introduce a series of basic Wi-Fi knowledge. Today, I will share knowledge about Wi-Fi signals. Wi-Fi signals are transmitted through radio waves; therefore, interference and attenuation are inevitable. The further away from a wireless router, the weaker the signals. Wi-Fi...
Control module: It is the core of the system control and service switching and aggregation. It can also function as the management and control core of the integrated network management system (NMS). Upstream module: It can provides four 10GE/GE upstream ports. Service processing module: It works together with...
By now, PPPoE and IPoE are widely used in the terminal accessing scenario. Though both of them are used to authenticate the access users, there is much difference between PPPoE and IPoE. We’ll talk about the difference in this post. Generally, we access the internet through the PPPoE dialer, in...
Why do we need to upgrade to XG(S)-PON? XG(S)-PON is evolved from the existing GPON technology, the factors promoting the technology evolution to XG(S)-PON are as follows: With the rise of new services such as 4K/8K video, AR, VR, and smart home solutions, the demand for bandwidth is increasing at a...
What is DHCP? DHCP (Dynamic Host Configuration Protocol) is a standardized client/server network protocol that dynamically assigns IP addresses and other related configuration information to network devices. As you know, each device in a TCP/IP network should have a unique IP address to access the network. Therefore, if your network...
Hello everyone! Today I will share with you the related issues of LAN / MAN / WAN. 1. Basic concept of local area network (LAN) Definition of local area network: LAN is a communication network that interconnects various communication devices in a small area. There are three main technologies that determine...
At present, WDM (Wavelength Division Multiplexing) technology is developing very rapidly, and has shown great vitality and bright development prospects. In the same optical fiber, two or more optical wavelength signals are transmitted through different optical channels at the same time, which is called optical wavelength division multiplexing technology, or...
Continuing from the previous introduction, on the basis of understanding the working principle, next, let's take a look at the classification and characteristic parameters of EDFA. Classification of DFA According to the different pumping methods of the pump light source, EDFA has three different structural forms: (1) Co-directional pumping structure Pumping in the...
EDFA, also known as Erbium-doped Fiber Amplifier, is a special kind of optical fiber, in which the rare earth element erbium (Er) is injected into the fiber core, so that under the action of the pump light source, the optical signal of a certain wavelength can be directly amplified. Its...
When we log in to the firmware of some routing ONTs or home routers through the webpage, we will see that there is an option called PPPoE at the location of the WAN connection, so what is PPPoE? PPPoE is the point-to-point protocol running over the Ethernet at the link...
What Is an ONT An optical network terminal (ONT) is a device that provides a network for home users. It offers high-speed Internet access, IPTV, voice, and Wi-Fi services. ONT vs. ONU An ONT can be regarded as an optical network unit (ONU), but it is a part of an ONU in...
