The optical network unit (ONU) supplies network services from the PON to customer premises, connecting customer-premises equipment such as a home gateway or office firewall. An optical network terminal (ONT) is an ONU that functions as a demarcation point servicing a single subscriber; e.g., a
As with an HFC architecture, video controllers and data-networking services are fed through a CMTS/edge router. These electrical signals are then converted to optical ones, and transported via a 1550 nm wavelength through a wavelength-division multiplexing (WDM) platform and a passive splitter to a fiber-optic micro-node located at the customer premises.
These devices have multiple audio and video inputs and one RF output. Audio/video outputs from source devices such as a DVD player, VCR, or DSS receiver are connected to the audio/video inputs on the modulator. The modulator is then programmed to broadcast the signals on a certain frequency. That RF broadcast is then received by the connected TV.
Radio-frequency (RF) engineering is a subset of electrical engineering involving the application of transmission line, waveguide, antenna, radar, and electromagnetic field principles to the design and application of devices that produce or use signals within the radio band, the frequency range of about 20 kHz up to 300 GHz.

A speaker giving a presentation with an RF pointer in his left hand. Using a wireless clicker, helps the presenter to move freely, instead of being obliged to stay next to the computer, can get closer and keep in touch with the audience, watching the presentation together with them, being able to use the built-in laser pointer, in order to emphasize specific points in the dialogue with the ...
Radio over fiber (RoF) or RF over fiber (RFoF) refers to a technology whereby light is modulated by a radio frequency signal and transmitted over an optical fiber link. Main technical advantages of using fiber optical links are lower transmission losses and reduced sensitivity to noise and electromagnetic interference compared to all-electrical signal transmission.
Radio Frequency Systems (RFS) is a designer and manufacturer of wireless and broadcast cable solutions and accessories.Established in 1900, RFS operates across multiple sectors, including telecommunications, broadcasting, and industries including rail [1] and mining.
Video signals are usually encoded into binary digit (0, 1) or seven digit pulse-code modulation (PCM), which is a method used to digitally represent original video signal. . The video signal converted to binary digit PCM at the point of origin can be then transmitted over existing telephone cable or wire directly to the destination
