  2. Twisted pair - Wikipedia

    en.wikipedia.org/wiki/Twisted_pair

    A twisted pair can be used as a balanced line, which as part of a balanced circuit can greatly reduce the effect of noise currents induced on the line by coupling of electric or magnetic fields. The idea is that the currents induced in each of the two wires are very nearly equal. The twisting ensures that the two wires are on average the same ...

  3. Small Form-factor Pluggable - Wikipedia

    en.wikipedia.org/wiki/Small_Form-factor_Pluggable

    Small Form-factor Pluggable connected to a pair of fiber-optic cables. Small Form-factor Pluggable (SFP) is a compact, hot-pluggable network interface module format used for both telecommunication and data communications applications. An SFP interface on networking hardware is a modular slot for a media-specific transceiver, such as for a fiber ...

    25-pair telco cable pinout. A common application of the 25-pair color code is the cabling for the Registered Jack interface RJ21, which uses a female 50-pin miniature ribbon connector, as shown in the following table. The geometry of the pins of the receptacle (right hand image) corresponds to the pin numbers of the table.

  8. Category 5 cable - Wikipedia

    en.wikipedia.org/wiki/Category_5_cable

    Category 5 cable (Cat 5) is a twisted pair cable for computer networks. Since 2001, the variant commonly in use is the Category 5e specification (Cat 5e). The cable standard provides performance of up to 100 MHz and is suitable for most varieties of Ethernet over twisted pair up to 2.5GBASE-T [1][2][3][4] but more commonly runs at 1000BASE-T ...

  9. Hybrid fiber-coaxial - Wikipedia

    en.wikipedia.org/wiki/Hybrid_fiber-coaxial

    Digital subscriber line (DSL) is a technology used by traditional telephone companies to deliver advanced services (high-speed data and sometimes video) over twisted pair copper telephone wires. It typically has lower data carrying capacity than HFC networks and data speeds can be range-limited by line lengths and quality.
