Upstream speeds are also important to users of peer-to-peer software. Residential services often have higher downstream rates than upstream, while business services are often symmetric. ADSL and cable modems are asymmetric , with the upstream data rate much lower than that of its downstream.
VDSL offers speeds of up to 52 Mbit/s downstream and 16 Mbit/s upstream, [3] over a single twisted pair of copper wires using the frequency band from 25 kHz to 12 MHz. [4] These rates mean that VDSL is capable of supporting applications such as high-definition television , as well as telephone services ( voice over IP ) and general Internet ...
Sckipio 24-port DPU (Distribution point unit), provides G.fast service. G.fast is a digital subscriber line (DSL) protocol standard for local loops shorter than 500 meters, with performance targets between 100 Mbit/s and 1 Gbit/s, depending on loop length. [1]
Digital subscriber line (DSL; originally digital subscriber loop) is a family of technologies that are used to transmit digital data over telephone lines. [1] In telecommunications marketing, the term DSL is widely understood to mean asymmetric digital subscriber line (ADSL), the most commonly installed DSL technology, for Internet access.
Traditional DOCSIS upstream in North America uses the 5–42 MHz frequency range. The 5–65 MHz range is used by EuroDOCSIS. This is known as a "low-split" or "sub-split" design, capable of a total shared capacity of ~108 Mbit/s upstream (assuming 4 SC-QAM upstream channels) for the service group. [24]
NG-PON2 (also known as TWDM-PON), Next-Generation Passive Optical Network 2 is a 2015 telecommunications network standard for a passive optical network (PON). The standard was developed by ITU and details an architecture capable of total network throughput of 40 Gbit/s, corresponding to up to 10 Gbit/s symmetric upstream/downstream speeds available at each subscriber.

The 10 Gbit/s Ethernet Passive Optical Network standard, better known as 10G-EPON allows computer network connections over telecommunication provider infrastructure. The standard supports two configurations: symmetric, operating at 10 Gbit/s data rate in both directions, and asymmetric, operating at 10 Gbit/s in the downstream (provider to customer) direction and 1 Gbit/s in the upstream ...
