What is DOCSIS?

  Data Over Cable Service Interface Specification (DOCSIS /ˈdɒksɪs/) is an international telecommunications standard that permits the addition of high-bandwidth data transfer to an existing cable TV (CATV) system. It is employed by many cable television operators to provide Internet access (see cable Internet) over their existing hybrid fiber-coaxial (HFC) infrastructure. The various standards are sometimes abbreviated to Dx, as in a “D3 modem” (DOCSIS 3 modem).

DOCSIS Cable

  DOCSIS was developed by CableLabs and contributing companies, including 3Com, ARRIS, BigBand Networks, Broadcom, Cisco, Conexant, Correlant, Harmonic, Hitron Technologies, Intel, Motorola, Netgear, Technicolor, Terayon, and Texas Instruments

What is MoCA (Multimedia over Coax Alliance)?

Tips: There are two versions of the specification currently available, MoCA 1.1 and MoCA 2.0.

  Multimedia over Coax Alliance (MoCA) is an industry standard alliance developing technology for the connected home. MoCA technology runs over the existing in-home coaxial cabling, enabling whole-home distribution of high definition video and content.

Applications:

  • In-home backbone for wireless network extension
  • Multiroom digital video recorders (DVRs)
  • Over-the-top (OTT) streaming content
  • Gaming
  • HDTV, Ultra HDTV and 3D TV

What is HomePlug?

  HomePlug is the family name for various power line communications specifications under the HomePlug moniker, with each offering unique performance capabilities and coexistence or compatibility with other HomePlug specifications.

  Some HomePlug specifications target broadband applications such as in-home distribution of low data rate IPTV, gaming, and Internet content, while others focus on low-power, low throughput, and extended operating temperatures for applications such as smart power meters and in-home communications between electric systems and appliances. All of the HomePlug specifications were developed by the HomePlug Powerline Alliance, which also owns the HomePlug trademark.

What is EoC technology?

  Ethernet over Coax (EoC) is a family of technologies that supports the transmission of Ethernet frames over coaxial cable.

Tips: EoC, Compliant with HomePlug AV, IEEE 802.1q, IEEE802.3, IEEE 802.3x/u
  HomePlug AV/HomePlug AV2 standards utilize low frequencies, strictly under FM radio (87.5 MHz). Development of this technology uses advanced modulations, 4096 QAM and higher and wider band. Qualcomm/Atheros and Spidcom are now (04/2014) two major HomePlug chip producers.

What is G.fast (G.now/G.hn etc)?

  G.fast is a digital subscriber line (DSL) standard for local loops shorter than 500 m, with performance targets between 150 Mbit/s and 1 Gbit/s, depending on loop length. High speeds are only achieved over very short loops. Although G.fast was initially designed for loops shorter than 250 meters, Sckipio in early 2015 demonstrated G.fast delivering speeds over 100 megabits nearly 500 meters and the EU announced a research project.
