4.1 Directional couplers
To understand the operation of a directional coupler, you must understand the terms directional and coupler.
First, let us look at the term coupler. If two transmission...
Optical data transmission (ODT) offers a means of sending data between moving objects without some of the drawbacks associated with radio-frequency and wired-communications methods. ODT essentially...
12.4 FIBER OPTIC COUPLERS
In fiber optic communication systems, it is often necessary to tap a small amount of
power from the signal. It may also be necessary to split the signal into two (or...

Power Dividers As discussed earlier, one of the most important applications of
a fiber directional coupler is as a power divider. In many applications, such as in
