People who often buy optical Modules know that optical fiber modules usually need to confirm the compatibility code, because there are currently two types on the market, one is a high-performance compatible module, and the other is an optical module of the ori...

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 addit...

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 swit...

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 f...

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-...

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 sec...

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...

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 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 ...

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...
