The serial port server provides the function of serial port to Internet, which can convert the RS-232/485/422 serial port into a TCP/IP network interface, and maintain the two-way Transparent transmission of statistical data between the RS-232/485/422 serial p...

Industrial Switches specialize in designing solutions to meet the requirements of flexible and varied industrial production applications, and present a cost-effective power line communication communication solution. Industrial switches are also divided into t...

In the field of communication networks, we often use fiber optic transceivers and protocol converters, but friends who don't know much about them may confuse the two. So, what is the difference between fiber optic transceivers and protocol converters? The conc...

Some customers asked, there are POE switches on the market that claim to be able to transmit 150 meters or even 250 meters, is it true or false? First of all, we need to understand what POE is. POE is the abbreviation of Power over Ethernet, which means that w...

PDH optical transceiver (Plesiochronous Digital Hierarchy), a quasi-synchronous digital transmission series system. PDH optical transceivers are small-capacity optical transceivers. PDH optical transceivers are generally used in pairs, also called point-to-poi...

Optical transceiver is the terminal equipment for optical signal transmission. Optical transceivers should be classified into telephone optical transceivers, video optical transceivers, audio optical transceivers, data optical transceivers, Ethernet optical tr...
