A DSL filter (also DSL splitter or microfilter) is an analog low-pass filter installed between analog devices (such as telephones or analog modems) and a plain old telephone service (POTS) line. The DSL filter prevents interference between such devices and a digital subscriber line (DSL) service connected to the same line.
Modern ADSL filter/splitter (left) and filter (right). ADSL works by using spectrum above the band used by voice telephone calls. [1] With a DSL filter, often called splitter, the frequency bands are isolated, permitting a single telephone line to be used for both ADSL service and telephone calls at the same time.
Hybrid Networks developed, demonstrated and patented the first high-speed, asymmetrical cable modem system in 1990. A key Hybrid Networks insight was that in the nascent days of the Internet, data downloading constitutes the majority of the data traffic, and this can be served adequately with a highly asymmetrical data network (i.e. a large ...
Digital subscriber line (DSL) is a technology used by traditional telephone companies to deliver advanced services (high-speed data and sometimes video) over twisted pair copper telephone wires. It typically has lower data carrying capacity than HFC networks and data speeds can be range-limited by line lengths and quality.
This splitter separates the DSL and voice bands. Thus the customer will have a dial tone, which allows them to use the telephone line as a regular land line while they are using it to access the Internet on their computer. A cable carrying both services runs from the splitter to the cable head, where it continues on to the customer on outside ...
The term “broadband” refers to a high-speed internet connection that uses a satellite, digital subscriber line or cable connection for data transmission. A broadband connection is usually a lot faster than a dial-up connection and allows you to browse the web and download videos, music and games much more quickly.
The exact kind of fibre cable and connectors to use is undefined but is broadly using SC/APC connectors. [6] The primary optical transmitter, known as the optical line terminal (OLT), is housed within the central office of the telecommunications operator. A laser in the OLT injects photons from the central office into a glass-and-plastic fiber ...
Very high-speed digital subscriber line (VDSL) [1] and very high-speed digital subscriber line 2 (VDSL2) [2] are digital subscriber line (DSL) technologies providing data transmission faster than the earlier standards of asymmetric digital subscriber line (ADSL) G.992.1, G.992.3 (ADSL2) and G.992.5 (ADSL2+).
