PoE switches can be widely used in the field of security monitoring and must have their core advantages. The smart PoE switch that does not burn devices launched by Shenzhen JHA Technology has been very popular. What are the benefits of using PoE?Summarize the...

Everyone knows that industrial switches have optical ports and electrical ports. An industrial switch can have all electrical ports or a free combination of optical and electrical ports. Sometimes, customers will ask such a question. Does the interface have an...

Speaking of SFP optical modules, we are all familiar with it. SFP stands for SMALL FORM PLUGGABLE (Small Pluggable). It is one of the most commonly used packages for Gigabit Ethernet optical modules and an industry standard for Gigabit Ethernet. So, what are t...

There are various types of industrial switches, which can be divided into manageable industrial switches and unmanaged switches. According to the installation method, they can be divided into rail-mounted industrial switches and rack-mounted industrial switche...

At present, there are many types of fiber optic transceivers on the market, such as unmanaged fiber optic transceivers, network managed fiber optic transceivers, industrial-grade fiber optic transceivers, and PoE fiber optic transceivers. All of these fiber op...

Nowadays, video surveillance is an indispensable infrastructure in all walks of life. The construction of network video surveillance systems makes it easier to monitor public places and obtain information. However, with the popularization of high-definition an...

The light we are most familiar with is of course the light we can see with the naked eye. Our eyes are very sensitive to purple light with a wavelength of 400nm to red light at 700nm. But for optical fibers that carry glass fibers, we use light in the infrare...

In order to meet the growing demand for networks in extreme environments, more and more industrial-grade fiber media converters are used in extremely harsh environments to extend the transmission distance. So, what is the difference between industrial grade fi...

Researchers at Penn State University in the United States said that soon, the semiconductor core fiber itself may be able to perform expensive "electrical-optical-electrical" conversion without relying on the electric-optical ( electronic-optical) converters, ...
