    Passive DC-to-DC injectors also exist which convert a 9 V to 36 V DC, or 36 V to 72 V DC power source to a stabilized 24 V 1 A, 48 V 0.5 A, or up to 48 V 2.0 A PoE feed with '+' on pins 4 & 5 and '−' on pins 7 & 8. These DC-to-DC PoE injectors are used in various telecom applications. [57]

    en.wikipedia.org/wiki/Manifold_injection

    From 1992 to 1996 General Motors implemented a system called Central Port Injection or Central Port Fuel Injection. The system uses tubes with poppet valves from a central injector to spray fuel at each intake port rather than the central throttle body [citation needed]. Fuel pressure is similar to a single-point injection system.

  4. Network switch - Wikipedia

    Through port mirroring, a switch can create a mirror image of data that can go to an external device, such as intrusion detection systems and packet sniffers. A modern switch may implement power over Ethernet (PoE), which avoids the need for attached devices, such as a VoIP phone or wireless access point, to have a

    Terabit Ethernet (TbE) is Ethernet with speeds above 100 Gigabit Ethernet.The 400 Gigabit Ethernet (400G, 400GbE) and 200 Gigabit Ethernet (200G, 200GbE) [1] standard developed by the IEEE P802.3bs Task Force using broadly similar technology to 100 Gigabit Ethernet [2] [3] was approved on December 6, 2017.

    en.wikipedia.org/wiki/Bias_tee

    A bias tee is a three-port network used for setting the DC bias point of some electronic components without disturbing other components. The bias tee is a diplexer.The low-frequency port is used to set the bias; the high-frequency port passes the radio-frequency signals but blocks the biasing levels; the combined port connects to the device, which sees both the bias and RF.
