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...

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 ...

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, J...

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 wo...

S485/232/422 serial ring network self-healing optical transceiver provides 2 RS485 ports or 1 RS232 port for bidirectional communication on the fiber ring network at the same time. Only one master station is allowed in a ring network, and the others are slave...
