With the application of PON(Passive Optical Network), it’s not out of ordinary to find ONU deployed in many families’ houses. According to different application scenarios, ONU can be divided into SFU, HGU, SBU, MDU, and MTU. HGU and SFU are the most heard in life. But seldom do people know that actually they belong to ONU and their distinction. Now in this article, let’s explore what an HGU router is and its difference from SFU. 1. What is HGU Router? ONU can be divided into SFU (Single Family Unit), HGU(Home Gateway Unit) and

When you travel or go to some remote regions, you may be annoyed with the poor signal. Is there any way to get a strong WiFi router signal outdoor in a 4G LTE network? Greatly, the V-SOL outdoor 4G CPE router would be a good choice! Part I. What is the Outdoor 4G CPE Router? V-SOL outdoor 4G CPE router XYC1841 is different from a WiFi-only router, which needs to connect with the fiber-optic network. The 4G CPE WiFi router can receive the operator’s 4G LTE network signals and convert them into broadband and Wi-Fi. You only need to insert

In the market, most businesses like Huawei or ZTE offer CS-EMS to manage the OLT (Optical Line Terminal). V-SOL also has this software. However, in order to improve the efficiency and quality of management, V-SOL developed a brand-new system BS-EMS, which would bring operators a better experience and users a securer network. Now let’s start to learn more about BS-EMS! Part I. What is BS-EMS? BS-EMS refers to Element Management System integrated with BS (Browser/Server) architecture. There are five aspects that EMS makes a difference in, which include fault, configuration,

Part I. Introduction of TR-069 TR-069 (Technical Report-069) is a communication protocol developed on CWMP (CPE WAN Management Protocol) and the communication link between CPE (Customer Premise Equipment) and ACS (Auto-Configuration Server). With the protocol, CPE can achieve indispensable measures of initialization and operation such as service provision, function setting, the upload and download of files, system detection, etc. Part II. Features of TR-069 Protocol ✔ Automatic configuration of user equipment and dynamic service configuration For ACS, each user’s equipment can mark its model, version, and other info in the protocol. According to

In the past, the campus network always adopts traditional cabling methods. With the development of new technology like AR/VR, 4k/8k videos, WiFi 6, etc., the network traffic shoots up and some problems of the network are exposed. For instance, there is no way to manage the network uniformly because there are lots of devices and fault points. It cost a lot to set up a sole network for each of the multiple systems. In this circumstance, POL is created to solve the problems. Part I. What is Passive Optical LAN

The Internet has become an indispensable thing in our life. As the carrier of the network, what’s the difference among ONU, router and Switch? How can we distinguish them? In this article, we will answer these questions. At first, let’s get to know what ONU, router and switch are. Part I. What are ONU, router and switch? 1. ONU ONU (Optical Network Unit) is also called optical modem, which is a device similar to the baseband modem. But the difference is ONU accesses optical fiber. It converts the digital signal into

With the development of 5G/10G and Ultra High Definition Video, the demands for over 1GbE network interface are increasing. Although 10GbE has existed, it requires advanced technology and higher cost. At the moment, 2.5GbE which is between 1GbE and 10GbE is created. More and more devices support a 2.5GbE port. Besides, many laptops no longer provide Ethernet ports so people should use USB to RJ45 to have a 2.5GbE LAN port. Then, what is 2.5GbE exactly and what features can it bring? Below we will explain. Before that, let’s get to know
