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 -
Which ONU equipment is better for the monitoring system?
Nowadays, in social cities, surveillance cameras are basically installed in every corner. We will see various surveillance cameras in many residential buildings, office buildings, shopping malls, hotels and other places to prevent the occurrence of illegal activities. With the steady development ...Read more -
What is an ONU device?
ONU (Optical Network Unit) optical network unit, ONU is divided into active optical network unit and passive optical network unit. Generally, devices equipped with network monitoring including optical receivers, upstream optical transmitters, and multiple bridge amplifiers are called optical node...Read more -
OTN in the era of all-optical network 2.0
The way of using light to transmit information can be said to have a long history. The modern “Beacon Tower” has allowed people to experience the convenience of transmitting information through light. However, this primitive optical communication method is relatively backward, limited...Read more -
How to quickly distinguish between switches and routers
What is a router? Routers are mainly used in local area networks and wide area networks. It can connect multiple networks or network segments to “translate” data information between different networks or network segments, so that they can “read” each other’s data to ...Read more -
What are the main types of ONU equipment used by fiber-optic broadband clients?
1. The ONU equipment used by the client is mainly as follows: 1) In terms of the number of LAN ports, there are single-port, 4-port, 8-port and multi-port ONU devices. Each LAN port can provide bridging mode and routing mode respectively. 2) According to whether it has WIFI function or not, it ca...Read more -
What is the difference between an ordinary ONU and an ONU that supports POE?
Security people who have worked in PON networks basically know ONU, which is an access terminal 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 fibe...Read more -
How to distinguish optical access network OLT, ONU, ODN, ONT?
The optical access network is an access network that uses light as the transmission medium, instead of copper wires, and is used to access every household. Optical access network. Optical access network generally consists of three parts: optical line terminal OLT, optical network unit ONU, optica...Read more -
It turns out that the application of optical fiber modules is so wide
In the cognition of many people, what is an optical module? Some people answered: it is not composed of an optoelectronic device, a PCB board and a housing, but what else does it do? In fact, to be precise, the optical module is composed of three parts: optoelectronic devices (TOSA, ROSA, BOSA), ...Read more -
Types of fiber amplifiers
When the transmission distance is too long (more than 100 km), the optical signal will have a great loss. In the past, people usually used optical repeaters to amplify the optical signal. This kind of equipment has certain limitations in practical applications. Replaced by optical fiber amplifier...Read more
