Types of beam splitters in optical distribution boxes
Optical distribution boxes commonly use Fused Biconical Taper (FBT) splitters and Planar Lightwave Circuit (PLC) splitters, along with cube and plate beam splitters for specific optical applications.
Fiber-Optic Splitters
1. Fused Biconical Taper (FBT) Splitters FBT splitters are widely used in passive optical networks (PONs) for smaller split configurations such as 1×2, 1×4, or 2×2. They are made by removing the coating from two fibers, twisting and heating them to form a double-cone structure. This allows precise control of the splitting ratio by adjusting the fiber stretch and torsion angle. FBT splitters are cost-effective but can be temperature-sensitive and have wavelength-dependent losses . 2. Planar Lightwave Circuit (PLC) Splitters PLC splitters are fabricated using photolithography on a silica glass substrate to create integrated waveguides. They are ideal for larger split ratios and provide uniform splitting with minimal loss. PLC splitters are more compact, spectrally uniform, and less sensitive to wavelength variations compared to FBT splitters, making them suitable for high-density optical distribution boxes .
Free-Space Beam Splitters
1. Cube Beam Splitters Cube splitters consist of two right-angle prisms cemented together with a partially reflective coating on the hypotenuse. They are used to split or combine light beams in free-space optical systems. Cube splitters can be polarizing or non-polarizing, depending on the coating and application . 2. Plate Beam Splitters Plate splitters are thin, flat glass plates coated on one surface to reflect part of the light while transmitting the rest. They are often used at a 45° angle of incidence and are lighter and more compact than cube splitters. Plate splitters are cost-effective and suitable for applications where low chromatic aberration and simple assembly are important .
Polarizing vs Non-Polarizing Splitters
- Polarizing Beam Splitters (PBS) separate light into orthogonal polarization states, reflecting S-polarized light and transmitting P-polarized light. They are used in optical isolation and polarization-sensitive applications .
- Non-Polarizing Beam Splitters (NPBS) split light without regard to polarization, commonly used in general optical distribution where polarization is not critical .
Summary
In an optical distribution box, the most common beam splitters are FBT and PLC fiber-optic splitters for signal branching, while cube and plate splitters are used in free-space optical setups. Depending on the application, splitters may be polarizing or non-polarizing, and the choice depends on factors like split ratio, wavelength uniformity, and environmental stability .
