A fiber fused coupler is one of the most popular passive components for wavelength multi/demultiplexing or branching/combining of optical signal. They are used to split optical signals between two fibers, or to combine optical signals from two fibers into one fiber. Fused couplers do suffer from some disadvantage. Multimode fused couplers are mode dependent. Single fused couplers only transmit one mode, so they do not suffer from mode dependency.

It does this by taking power from a power supply and increasing the output to match the (relatively low-power) input signal. This process invariably introduces some noise and distortion into the signal; and the process cannot be 100% efficient at increasing the gain without loss — amplifiers inherently will lose some energy in the form of heat. The ideal amplifier can be described as "a straight wire with gain," as the output would be identical to the input, just greater.

Gastroenterology involves the overall understanding of the normal gastrointestinal organs action. Gastroenterologists have to understand motility - the movement of material through the stomach and intestine, the digestion and absorption of nutrients and the function of the liver.
