  2. Cable modem termination system - Wikipedia

    en.wikipedia.org/wiki/Cable_modem_termination_system

    A given headend may have between 1–12 CMTSs to service the cable modem population served by that headend or HFC hub. One way to think of a CMTS is to imagine a router with Ethernet interfaces (connections) on one side and coaxial cable RF interfaces on the other side. The Ethernet side is known as the Network Side Interface or NSI.

  3. Cable modem - Wikipedia

    en.wikipedia.org/wiki/Cable_modem

    The PSTN-based service was considered 'one-way cable' and had many of the same drawbacks as satellite Internet service; as a result, it quickly gave way to "two-way cable." Cable modems that used the RF cable network for the return path were considered 'two-way cable', and were better able to compete with the bi-directional digital subscriber ...

  4. RF connector - Wikipedia

    en.wikipedia.org/wiki/RF_connector

    Various popular RF connectors Electronic symbols for the plug and jack coaxial connectors Time-domain reflectometry shows reflections due to impedance variations in mated RF connectors. An RF connector (radio frequency connector) is an electrical connector designed to work at radio frequencies in the multi-megahertz range.

  5. Radio frequency over glass - Wikipedia

    en.wikipedia.org/wiki/Radio_frequency_over_glass

    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 ...

  6. Radio over fiber - Wikipedia

    en.wikipedia.org/wiki/Radio_over_fiber

    Electrical RF is directly connected to a TV or set-top box. 1550 nm is more popular because it has less losses in the fiber and by using fiber-optic amplifier known as EDFA it is possible to extend the transport distance. 1310 nm loses about 0.35 dB/km of optical signal, 1550 nm loses only 0.25 dB/km. Optical budget between transmitter and ...

  7. F connector - Wikipedia

    en.wikipedia.org/wiki/F_connector

    The F connector (also F-type connector) is a coaxial RF connector commonly used for "over the air" terrestrial television, cable television and universally for satellite television and cable modems, usually with RG-6/U cable or with RG-59/U cable.

  8. 7/16 DIN connector - Wikipedia

    en.wikipedia.org/wiki/7/16_DIN_connector

    The 7-16 DIN connector or 7/16 (seven and sixteen millimeter DIN) is a 50 Ω threaded RF connector used to join coaxial cables. It was designed to reduce passive intermodulation from multiple transmitters. It is among the most widely used high power RF connectors in cellular network antenna systems. Originally popular in Europe, it has gained ...

  9. RF switch matrix - Wikipedia

    en.wikipedia.org/wiki/RF_Switch_Matrix

    A PIN Diode RF Microwave Switch. There are two types of switches typically used in switch matrices: Coaxial Electromechanical Switches and Solid State Switches, also known as electronic switches. Coaxial electromechanical switches can be further divided into two categories based on their architecture, latching relay and non-latching relay.
