2. Power dividers and directional couplers - Wikipedia

   en.wikipedia.org/wiki/Power_dividers_and...

   A 3 dB 2.0–4.2 GHz power divider/combiner. Power dividers (also power splitters and, when used in reverse, power combiners) and directional couplers are passive devices used mostly in the field of radio technology. They couple a defined amount of the electromagnetic power in a transmission line to a port enabling the signal to be used in ...

3. Hybrid fiber-coaxial - Wikipedia

   en.wikipedia.org/wiki/Hybrid_fiber-coaxial

   RF amplifiers called trunk amplifiers are used at intervals in the trunk to overcome cable attenuation and passive losses of the electrical signals caused by splitting or "tapping" the coaxial cable. Trunk cables also carry AC power which is added to the cable line at usually either 60 or 90 V by a power supply (with a lead acid backup battery ...

4. Fiber-optic splitter - Wikipedia

   en.wikipedia.org/wiki/Fiber-optic_splitter

   A fiber-optic splitter, also known as a beam splitter, is based on a quartz substrate of an integrated waveguide optical power distribution device, similar to a coaxial cable transmission system. The optical network system uses an optical signal coupled to the branch distribution. The fiber optic splitter is one of the most important passive ...

5. Power over Ethernet - Wikipedia

   en.wikipedia.org/wiki/Power_over_Ethernet

   In this configuration, an Ethernet connection includes Power over Ethernet (PoE) (gray cable looping below), and a PoE splitter provides a separate data cable (gray, looping above) and power cable (black, also looping above) for a wireless access point (WAP). The splitter is the silver and black box in the middle between the wiring junction box ...

6. Passive optical network - Wikipedia

   en.wikipedia.org/wiki/Passive_optical_network

   A passive optical network consists of an optical line terminal (OLT) at the service provider's central office (hub), passive (non-power-consuming) optical splitters, and a number of optical network units (ONUs) or optical network terminals (ONTs), which are near end users. [2][3] There may be amplifiers between the OLT and the ONUs. [4]
