HFC network

HFC network

(Hybrid Fiber-Coax network) A communications network (typically a cable TV network) that uses a combination of optical fibers and coaxial cable. The fiber provides the high-speed backbone, and the coax is used to connect end users to the backbone. Such networks typically use matching DOCSIS cable modems at the head end and the customer premises, providing bidirectional paths and Internet access. See DOCSIS.

Stable and reliable coax cable connections are crucial to a high performance HFC network. With demand on the network only set to grow, Corning Optical Communications is launching the TrueDrop portfolio, which includes F compression connectors and A++ Drop jumpers with a mating surface design.
According to the company, the HFC network upgrade opted for will be carried out to ensure the utility company's future capabilities in meeting subscribers' requirements for new, attractive services and greater bandwidth.
By leveraging the combination of DOCSIS 3.1 technology, passive HFC network characteristics, self-interference cancellation technology and intelligent scheduling, CableLabs -- along with the collaboration of its members and other industry partners -- developed this solution enabling full duplex communications over the existing HFC network.

Over time the nbntm HFC network is expected to service 2 Million premises Australia-wide, making up 25% of the overall nbntm connections.
It is upgrading its entire HFC network to support the new downstream extended frequency ranges defined in the DOCSIS 3.1 specification.
Much of the HFC network operated by Telstra and Optus, which for long suffered from underinvestment, is now being incorporated within the NBN, and with commercial DOCSIS3.1 technology likely to be deployed in 2017 investment in cable is again underway.
Mike Semmel, mapping supervisor, SECTV, said: "The seamless database structure of Bentley's HFC network engineering solution gives us an end-to-end perspective of our system that is simply not available from individual drawings, maps, and spreadsheets.
HFC network can carry many types of services which includes digital TV analog TV and high definition television (HDTV) the video on demand (VOD) variety of switched digital videos the common telephony and high-speed data [6] [7].
While GPON (Gigabit Passive Optical Network) is capable of providing 100 Mbps to each home, the cost of building and maintaining a GPON-based fiber network is much more expensive and skilled than with an HFC network. DOCSIS technology allows cable operators to reuse their existing cable plants to offer broadband services by upgrading them to two-way networks.
The end-to-end solution from ARRIS includes a centralised video and optical headend, HFC network, IPTV middleware as well as IP and cable set-top devices.
