Industrial ADSL & VDSL2 Modems

Industrial modems receive information from an Internet Service Provider (ISP) through phone lines (DSL), coaxial cables or optical fiber and converts it into a digital signal. This digital signal can now be utilized by an industrial router to get the information to connected devices through Ethernet cables or Wi-Fi. The speed and reliability of the information transmission can vary greatly depending on the type and design of the modem and router.
VDSL stands for Very high bit-rate Digital Subscriber Line and uses the copper wires in telephone lines to deliver high-speed Internet to devices. VDSL has some of the fastest download and upload speeds available. A VDSL modem is required to utilize VDSL and to achieve optimal Internet speeds. VDSL downstream and upstream speeds can reach up to 100 Mbps, while VDSL2 can possibly reach up to 200 Mbps. By comparison, this is significantly faster than the 8-10 Mbps speeds of ADSL.
ADSL stands for Asymmetric Digital Subscriber Line and transfers data over copper wires in telephone lines. While Symmetrical DSL (SDSL) downloads and uploads data at the same speed, ADSL has different data maximum transfer rates for downloading and uploading data. Because most users download more data than they upload, this difference usually does not make a noticeable impact on Internet access speeds. However, Web servers or other computers that send large amounts of data upstream, ADSL would be an inefficient choice.
