Fiber optic splitters, also known as beam splitters or couplers, are essential components in optical communication systems. They allow a single optical signal to be split into multiple signals or combined multiple signals into a single one. Fiber optic splitters work based on the principle of light wave interference and rely on the properties of the optical fibers used.
There are two main types of fiber optic splitters: fused couplers (also known as fused biconical taper couplers) and planar lightwave circuit (PLC) splitters. Here's how each type works:
Fused Couplers:
Planar Lightwave Circuit (PLC) Splitters:
In both types of splitters, the split signals retain the same optical properties, such as wavelength and phase, as the original input signal. This property allows fiber optic splitters to be used in various applications, such as distributing optical signals to multiple receivers in a network or combining signals from multiple transmitters into a single fiber.
Fiber optic splitters play a crucial role in optical communication systems, enabling the efficient and reliable distribution of optical signals over long distances with minimal signal loss or distortion.
