For new comers who are not familiar with the structure and functionality of Ethernet switch , they are apt to get confused with different ports built in for different connection. Except for those common ports on SFP switch, such as SFP port , there is another port called “combo SFP port”. Do you know what is it and what is the difference between SFP port and combo SFP port? In this article we aim to give you comprehensive understanding of combo SFP port on Ethernet switch. What Is Combo SFP Port on Ethernet Switch? In a nutshell, a combo SFP port is regarded as a single interface with dual front ends, i.e. an RJ-45 connector and an SFP (Small Form Pluggable) module (also called Mini-GBIC) connector. In other words, this is a compound port which can share the same switch fabric, port number and allow the users to configure their SFP switch according to different applications. But the two different physical ports can not be used simultaneously. It means that you can either plug a ca

With further enhancement of safety consciousness from general public, IP cameras are widely used in areas like schools, enterprises, public areas and even families. Using a PoE switch for IP security cameras to ensure the safety of people and business is a common and popular behavior nowadays. In this article we will intend to explore the advantages of using a PoE switch and help you choose a proper PoE switch for IP cameras as well. Figure1: PoE switch application Benefits of PoE Switch for IP Cameras When talking about PoE technology, some users may think that it is dispensable to buy a PoE switch with a relatively high price since a PoE injector can also achieve power supply and even space saving for IP cameras. But the reality is that if you have many PoE-enabled devices like 10 IP cameras, it is the optimal choice to use a PoE switch . In addition, it also provide the following benefits for IP cameras: Easy Management and Low Cost A PoE managed switch allows the p
