The very first HFC networks, and very old unupgraded HFC networks, are only one-way systems. Equipment for one-way systems may use POTS or radio networks to communicate to the headend. [103] HFC makes two-way communication over a cable network practical because it reduces the number of amplifiers in these networks. [1]
Networking cable is a piece of networking hardware used to connect one network device to other network devices or to connect two or more computers to share devices such as printers or scanners. Different types of network cables, such as coaxial cable , optical fiber cable , and twisted pair cables, are used depending on the network's topology ...
Telecommunications cable is a type of guided transmission medium. Telecommunications are based on transmitting and receiving modulated waves/signals through a medium. Types of telecommunications cable include: [1] [2] electrical cables when electric current is carried; transmission lines and waveguides when electromagnetic waves are transmitted; optical fibers when light signals are transmitted.
In US cable systems, equipment in the home sends a channel request signal back to the distribution hub. If a channel is requested, the distribution hub allocates a QAM channel and transmits the channel to the coaxial cable. For this to work, the home equipment must have two-way communication ability.
Wired communication refers to the transmission of data over a wire-based communication technology (telecommunication cables). Wired communication is also known as wireline communication . Examples include telephone networks , cable television or internet access , and fiber-optic communication .
Network address translator (NAT): network service (provided as hardware or as software) that converts internal to external network addresses and vice versa. [14] Residential gateway: interface between a WAN connection to an Internet service provider and the home network. Terminal server: connects devices with a serial port to a local area network.
MMDS microwave dish. Multichannel multipoint distribution service (MMDS), formerly known as broadband radio service (BRS) and also known as wireless cable, is a wireless telecommunications technology, used for general-purpose broadband networking or, more commonly, as an alternative method of cable television programming reception.
