What is the difference between a normal ONU and an ONU that supports PoE?
Security personnel who have done PON network basically know about ONU, which is an access device used in PON network, which is equivalent to the access switch in our usual network. The PON network is a passive optical network. The reason why it is said to be passive is that the optical fiber tran...Read more -
The development prospect of the switch
With the rapid development of cloud computing and virtualization technologies, the integration of data center services has put forward higher requirements for the performance, functions, and reliability of switches. However, because data center switches can carry various services, data transmissi...Read more -

What should I do if the fiber optic transceiver crashes?
Optical fiber transceivers are generally used in actual network environments where Ethernet cables cannot be covered and optical fibers must be used to extend the transmission distance. At the same time, they have also played a huge role in helping to connect the last mile of optical fiber lines ...Read more -
PON: Understand OLT, ONU, ONT and ODN
In recent years, fiber to the home (FTTH) has begun to be valued by telecommunication companies around the world, and enabling technologies are developing rapidly. There are two important system types for FTTH broadband connections. These are Active Optical Network (AON) and Passive Optical Netwo...Read more -
How are switch VLANs divided?
1. Divide VLAN according to port: Many network vendors use switch ports to divide VLAN members. As the name suggests, to divide VLAN based on ports is to define certain ports of the switch as a VLAN. The first-generation VLAN technology only supports the division of VLANs on multiple ports of the...Read more -
Is the optical modem connected to the switch or the router first
Connect the router first. The optical modem is connected to the router first and then to the switch, because the router needs to allocate ip, and the switch cannot, so it must be placed behind the router. If password authentication is required, of course, first connect to the WAN port of the ro...Read more -
Overview and functions of optical switches
Overview of Optical Switch: fiber optic switch is a high-speed network transmission relay device. Compared with ordinary switches, it uses fiber optic cables as the transmission medium. The advantages of optical fiber transmission are fast speed and strong anti-interference ability. Fibre Channe...Read more -
Six common faults of fiber optic transceivers
Fiber optic transceiver is an Ethernet transmission media conversion unit that exchanges short-distance twisted-pair electrical signals and long-distance optical signals. It is also called a photoelectric converter (Fiber Converter) in many places. 1. The Link light does not light up (1) C...Read more -
The difference between a switch and a router
(1) From the appearance, we distinguish between the two Switches usually have more ports and look cumbersome. The router’s ports are much smaller and the volume is much smaller. In fact, the picture on the right is not a real router but integrates the function of the router. In addition to the fu...Read more -
