Cable Coupler Vs Splitter

I am trying to connect three nodes a b c through rf cables in the following manner.

Cable coupler vs splitter.

An essential feature of directional couplers is that they only couple power. It is to distribute the input signal proportionally to multiple outputs. 3 5mm stereo mini phone 3 5mm. For example 10 db coupler the input signal is 50db then the output signals are direct out and coupled output respectively 50db minus insertion loss 40db minus insertion.

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. Splitters couplers adapters. A tap or directional coupler sends a fixed amount of signal such as 6db 10db 15db or 20db to the direction of the shorter cable run s and channels the rest of available signal in the direction of the longer cable run s. Whether it s a plain three plug metal block or an elaborate multi port device all cable splitters do the same thing.

8 way splitter has 11db loss on each leg and so on. The coupler can be thought of as a type of power splitter but it s not equally divided. The other is an active system which may also use a donor antenna coaxial cables active repeater master fiber unit remote fiber unit.

A can communicate with both b and c and vice versa but b and c cannot communicate directly. In this manner it provides equal broadcasting capability for all interior antennas. Coaxial cable splitters take in a cable signal line and channel it out into multiple signals typically to a couple of tvs and a high speed cable internet modem. The differences between tv splitters and couplers are quite few.

For the most part the serve the same purpose which is to split the cable signal input for distribution between two or more electronic devices. Keep in mind that splitters introduce loss in the return upstream direction as well. The differences between a splitter and coupler lay in how the devices are designed and achieve their purposes. Somebody suggested using a splitter for this work but when i tested one i found that all three nodes could communicate with each other.

They couple a defined amount of the electromagnetic power in a transmission line to a port enabling the signal to be used in another circuit.
