Fiber Optic Beam Splitters and Combiners: Precision Light Management for Fiber Systems
Fiber optic beam splitters and combiners are indispensable components in modern photonic systems, enabling the division or merging of optical signals in a controlled and efficient manner. These devices are widely used in telecommunications, fiber laser systems, sensing networks, and laboratory setups where signal routing and manipulation are critical. On FindLight, you’ll discover a comprehensive range of high-performance fiber splitters and combiners tailored for single-mode, multi-mode, and polarization-maintaining applications.
What Are Fiber Optic Beam Splitters and Combiners?
A fiber optic beam splitter divides an incoming optical signal into two or more outputs, typically in predefined ratios such as 50/50, 90/10, or 80/20. Conversely, a fiber combiner merges optical signals from multiple sources into a single output fiber. These components are constructed with precision fiber fusion or planar lightwave circuit (PLC) technology to ensure minimal signal loss, high uniformity, and stable performance over wide wavelength ranges.
Splitters and combiners can be designed for various wavelengths—most commonly for 850nm, 1310nm, and 1550nm—and are available in 1x2, 1x4, 2x2, and custom configurations.

Multiplexing and demultiplexing in photonic circuits
Whether you're building a passive optical network (PON), a lab interferometer, or a beam delivery system, fiber splitters and combiners offer reliable signal management.
Choosing the Right Fiber Splitter or Combiner
Important selection criteria include:
-
Wavelength Range: Match the component to your operating wavelength (e.g., 1310nm or 1550nm).
-
Split Ratio: Select based on how much power should be diverted (e.g., 50/50 vs 90/10).
-
Fiber Type: Choose single-mode, multi-mode, or polarization-maintaining depending on the system.
-
Connectorization: Available with bare fiber, or terminated with FC, SC, ST, LC, or custom connectors.
-
Environmental Durability: Ensure packaging and materials suit your application (e.g., lab, outdoor, or high-power use).
