How to realize POE power supply for ordinary switches?
PoE switch refers to a switch that can provide network power supply to remote powered terminals through a network cable. It is a relatively common power supply device in PoE power supply systems. However, if a switch does not have a POE function, can an additional poe power supply module be added...Read more -
Introduction to the use of optical modules
Optical module, especially refers to the small packaged optical module that can be hot-swapped. It is the optical module that can be hot-swapped during operation and used on the device port. It is mainly used to connect the device (generally refers to the switch or router device). The electrical ...Read more -
Which is better to use CWDM/DWDM Multiplexer?
CWDM/DWDM wavelength division multiplexing equipment usage As people’s requirements for bandwidth are getting higher and higher, Dense Wavelength Division Multiplexing (DWDM) devices have made great progress in reducing costs, and are therefore more and more favored in the market. However, ...Read more -
What is the difference between CWDM/DWDM Multiplexer?
In the construction of metropolitan area networks (especially long-distance OTN optical transmission networks), wavelength division multiplexing equipment is particularly important. DWDM dense wavelength division multiplexing equipment has long-distance, high-bandwidth transmission capabilities; ...Read more -
What causes the RS485 converter signal to be interfered?
The main function of the 485 converter is to convert a single-ended RS-232 signal into a balanced differential RS-485 or RS-422 signal. Due to long-distance information transmission and strong anti-interference ability, rs485 converters are widely used in security communication and other fields. ...Read more -
What are the reasons for the failure of the optical module?
The optical module is mainly used to convert the electrical signal in the device (usually referring to the switch or router device) into an optical signal, and then transmit it through an optical fiber (implemented by the transmitting end of the optical module), and can receive an external optica...Read more -
What is the difference between the RJ45 port and the SFP port of the switch?
As we all know, Gigabit Ethernet switches generally have two types of ports: RJ45 ports and SFP ports. Both types of ports can carry Gigabit Ethernet transmission, so what is the difference between them? What kind of port Gigabit Ethernet switch should be used to realize Gigabit Ethernet connecti...Read more -

Nowadays, video surveillance is an indispensable infrastructure for 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 and intelligent applications of video ...Read more -
How to use fiber optic transceivers in analog/IP network video surveillance systems?
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 optic transceivers can realize photoele...Read more -
How to deploy IP surveillance cameras using PoE switches?
Expensive IP camera surveillance systems were initially only economically available to large companies, but now IP surveillance systems are everywhere in daily life. This is because the prices of IP cameras and PoE switches have dropped significantly, so many people are trying to build A small IP...Read more -
Introduction to the advantages of PDH optical transceiver
PDH optical transceiver (Plesiochronous Digital Hierarchy, quasi-synchronous digital series) is a small-capacity optical transceiver, generally paired applications, also called point-to-point applications, and the capacity is generally 4E1, 8E1, 16E1. Next, JHA TECHNOLOGY will introduce the advan...Read more -
What are the advantages of using serial server networking?
With the development of new technologies, it has become convenient and cheap to connect any number or type of serial devices to the Ethernet. People use the Ethernet serial server to establish connections, manage communications, and transmit data around the world. So, what are the advantages of r...Read more
