Also called a low-noise block, [1] [2] low-noise converter (LNC), or even low-noise downconverter (LND), [3] the device is sometimes inaccurately called a low-noise amplifier (LNA). [ 4 ] The LNB is a combination of low-noise amplifier, frequency mixer , local oscillator and intermediate frequency (IF) amplifier.
Asynchronous Serial Interface, or ASI, is a method of carrying an MPEG Transport Stream over 75-ohm copper coaxial cable or optical fiber. [1] It is popular in the television industry as a means of transporting broadcast programs from the studio to the final transmission equipment before it reaches viewers sitting at home.
The signal loss in coaxial components led to the first widespread use of waveguide, extending the filter technology from the coaxial domain into the waveguide domain. [ 61 ] The wartime work was mostly unpublished until after the war for security reasons, which made it difficult to ascertain who was responsible for each development.
Low-noise block converter The circuit depicted in figure 1 is a low-noise block converter and is intended to be attached to a satellite television receiving dish antenna. It is called a block converter because it converts a large number of satellite channels as a block with no attempt to extract to a particular channel.
That is a traditional EPON deployment consisting of an OLT device and one or more ONU devices attached to the same PON with one or more new devices referred to functionally as an optical to Coax Media Converter (CMC) that attach one side to the PON and the other to a CxDN with their associated CNUs, where the communications over the coax media ...
In telecommunications, radio frequency over glass (RFoG) is a deep-fiber network design in which the coax portion of the hybrid fiber coax (HFC) network is replaced by a single-fiber passive optical network (PON). Downstream and return-path transmission use different wavelengths to share the same fiber (typically 1550 nm downstream, and 1310 nm ...
The Multimedia over Coax Alliance (MoCA) is an international standards consortium that publishes specifications for networking over coaxial cable.The technology was originally developed to distribute IP television in homes using existing cabling, but is now used as a general-purpose Ethernet link where it is inconvenient or undesirable to replace existing coaxial cable with optical fiber or ...
Hybrid fiber-coaxial (HFC) is a broadband telecommunications network that combines optical fiber and coaxial cable. It has been commonly employed globally by cable television operators since the early 1990s.
