Optical Splitters
Definition:
Optical splitters are passive optical devices that divide or combine optical signals from one or more sources into multiple outputs. They play a crucial role in optical fiber networks, enabling efficient signal distribution and management.
Types:
- Equal Splitters: Divide the input signal into equal power outputs.
- Unequal Splitters: Distribute the input signal unequally among the outputs.
- 2xN Splitters: Split an input signal into N equal or unequal outputs.
- N+1 Splitters: Combine N input signals into a single output.
Design:
- Fiber-Coupled Splitters: Use fused fiber technology to split the signal.
- Planar Lightwave Circuit (PLC) Splitters: Fabricated using semiconductor processes on a substrate.
- Array Waveguide Grating (AWG) Splitters: Utilize diffraction gratings to divide the signal.
Applications:
- Telecommunications: Dividing or combining signals for fiber-optic networks.
- Cable TV Distribution: Delivering TV signals to multiple subscribers.
- Industrial Automation: Connecting multiple sensors or actuators to a central control system.
- Medical Imaging: Distributing laser or LED light for diagnostic purposes.
Key Characteristics:
- Port Count: The number of input and output ports.
- Split Ratio: The ratio of the input power to the output power for each port.
- Insertion Loss: The optical power loss introduced by the splitter.
- Polarization Dependence: The variation in performance based on the polarization of the input light.
- Wavelength Range: The range of wavelengths over which the splitter operates efficiently.
Benefits:
- Signal Distribution: Allow for the efficient distribution of optical signals to multiple destinations.
- Power Management: Control the power levels of optical signals to prevent oversaturation or signal degradation.
- Noise Isolation: Isolate signals from different sources to prevent crosstalk.
- Cost-Effective: Provide a cost-effective solution for managing optical signals in large-scale networks.
Considerations:
- Wavelength Compatibility: Ensure that the splitter can handle the desired wavelengths of the signals.
- Loss Budget: Account for the insertion loss of the splitter when designing the network.
- Polarization Sensitivity: Consider the polarization sensitivity of the splitter if using polarized light.
- Power Handling Capacity: Select a splitter that can withstand the required power levels.

Optical splitter is an integrated waveguide optical power distribution device that serves to split optical signals. It is widely used in passive optical networks (such as EPON, GPON, BPON, FTTX, FTTH, etc.) and plays an important role.
When an optical signal is transmitted in a single-mode fiber, the optical energy cannot be completely concentrated in the fiber core, and a small amount of optical energy is propagated close to the fiber cladding. In general, when the distance between the cores of two optical fibers is close enough, the optical signal transmitted in one optical fiber can enter the other optical fiber, that is, the optical signal can be redistributed in the two optical fibers, which is exactly the origin of the optical splitter.
For example, a 1x4 optical splitter can distribute the optical signal in one optical fiber to four optical fibers in equal proportions. In fact, in simple terms, it is to distribute 1000Mbps bandwidth to four families equally, and each family can use a network with 250Mbps bandwidth.
