Introduction to G.hn EoC Technology Steve Staples FSCTE, Technical Sales Support Manager, Triax UK
to achieve with alternative technologies such as Mesh, Wi-Fi or Powerline. In MDU’s, the use of existing legacy telephone cabling is also not ideal and prone to incurring service level issues resulting in frustrated clients. EoC provides for a seamless transition from the fibre optic network, usually GPON, to the in-house coaxial cable network, delivering the full benefit of full fibre to places other technologies cannot reach. EoC utilises a more robust transmission path of screened coax cable, ensuring the same level of full fibre performance, as is delivered to the door, is received anywhere a coax outlet is installed. EoC achieves this by employing G.hn Wave 2 technology, which uses the lower frequency range of 2 to 200 MHz on the coaxial cable. Using this lower frequency range allows far greater distances to be achieved than traditional structured cable such as Cat6, whilst maintaining the Gigabit Network performance right to the end of the coax cable where it is required. By utilising this lower frequency band, it allows for the continued use of DVB-C, DVB-T and DVB-S services down the same coax cable. DVB-S, it should be noted, requires a multiswitch with a passive terrestrial path or alternatively, can be combined on to the coax cable after the multiswitch and separated before the end point with a TV/SAT Diplexer.
As the demand for ever faster speeds and bandwidth increases, the FTTH roll-out in the UK continues at some considerable pace. At the time of writing, more and more Homes and Apartment Blocks across the UK are being passed with Gigabit Fibre. However, this huge roll out exercise can sometimes fail at the final hurdle if home or building owners do not agree to the additional expense and disruption often incurred due to extensive re-cabling works (sometimes required within MDU residential properties or SDU homes) to get the Gigabit Network capability to where it is needed within the property. This is a common problem and there is a lot of misinformation out there. Once fibre has arrived at or in a building, many network operators and home owners are faced with the question of how to bridge the last few metres to the Apartments in MDU, or the rest of the Home in a SDU. If the existing building is not easy to re-cable (or it is a listed building), then the use of the existing coaxial cable network presents an ideal, cost effective and environmentally friendly solution. Ethernet over Coax or - “EoC”, utilises G.hn Wave 2 Technology and can provide a solution to this conundrum by providing that missing link from the fibre termination point to the rest of the home or building. Most consumers, if they have full fibre broadband, assume the speed at their front door will be the speed available throughout their property. This can be difficult
EoC enables a data rate of up to 1.6 Gbit/s on the coaxial cable between an EoC controller
