A Fiber Splitter, also commonly known as a Fiber Optic Splitter or an Optical Splitter, is a passive device used in fiber optic networks to distribute light signals from a single optical fiber to multiple optical fibers. It essentially functions as a signal divider, allowing a single light signal to be split and transmitted to multiple destinations without the need for amplification or active electronic components.
Here are some key points about Fiber Splitters:
-
Passive Device: As mentioned, a fiber splitter is a passive component, meaning it does not require power to operate. It simply divides the light signal based on the principles of optics.
-
Light Division: The splitter takes an incoming light signal and divides it into multiple output signals. The ratio of input to output signals can vary, depending on the specific splitter design. For example, a 1x4 splitter would divide one input signal into four output signals.
-
Signal Attenuation: Splitting a light signal into multiple outputs results in some loss of signal strength, known as attenuation. The amount of attenuation depends on the splitter's design and the number of output fibers.
-
Wavelength Division or Power Division: Fiber splitters can be categorized as wavelength division multiplexers (WDM) or power division splitters. WDM splitters separate signals by wavelength, while power division splitters distribute the power of the input signal among the output fibers.
-
Applications: Fiber splitters are widely used in fiber-to-the-home (FTTH) networks, fiber-optic sensors, and other applications where light signals need to be distributed to multiple locations.
-
Types: There are several types of fiber splitters, including fused biconical tapers (FBT), planar lightwave circuit (PLC) splitters, and mechanical splitters. Each type has its own advantages and disadvantages in terms of cost, performance, and reliability.
In summary, a Fiber Splitter is a crucial component in fiber optic networks that enables the efficient distribution of light signals to multiple destinations without the need for amplification.
