Bundled optical cables, or fiber optic bundles, come in customizable configurations including straight, bifurcated, fan-out, and fused-end designs, with options for single-mode, multimode, and specialized fibers.

Types and Configurations

1. Straight Bundles: Standard linear arrangements for transmitting light or signals from one point to another, often terminated with SMA, FC, or ST connectors . 2. Bifurcated (Y-Cable) Bundles: Split a single input into two outputs, commonly used in optogenetics or reflection probes, with dual ferrules or SMA/FC connectors . 3. Fan-Out Bundles: Multiple fibers spread out from a single bundle to connect to different devices or sensors, ideal for complex instrumentation . 4. Fused-End Bundles: Fibers are permanently fused at one end to create a homogeneous optical surface, providing low-loss, high-stability light distribution for spectroscopy or laser applications . 5. Custom Geometries: Bundles can be arranged in round, square, hexagonal, linear, or fully custom patterns to achieve precise light shaping, homogenization, or targeted distribution .

Fiber Types and Specifications

• Single-Mode Fibers: For long-distance, low-loss signal transmission.
• Multimode Fibers: Core sizes from 25 µm to 1800 µm, numerical apertures (NA) from 0.10 to 0.66, suitable for high-power or short-distance applications .
• Specialty Fibers: High OH, low OH, mid-IR fluoride fibers, polarization-maintaining fibers, and metal-coated fibers for high-temperature or high-power environments .

Connectors and End Terminations

• Standard connectors: SMA, FC, ST, SC, LC, MTP.
• Custom machined ferrules: round, square, rectangular, or slit-shaped.
• End caps available to reduce power density and increase laser damage threshold .

Applications

• Spectroscopy, laser systems, and photonics instrumentation.
• Medical devices: endoscopy, photodynamic therapy, diagnostic systems.
• Industrial sensing, chemical analysis, and high-power laser delivery.
• Research applications: DNA sequencing, optical tomography, and optogenetics .

Customization Options

• Fiber count: from a few fibers to thousands in 1D or 2D arrays.
• Lengths: up to 100 meters or more, with precise tolerances.
• Jackets: polymer, metal, or monocoil for environmental protection.
• Coatings: aluminum, gold, or anti-reflective treatments for high-temperature or high-power use . Bundled optical cables are highly versatile and can be tailored to meet specific technical requirements, making them suitable for a wide range of industrial, medical, and research applications. For precise model selection, contacting manufacturers like FiberTech Optica, Thorlabs, CeramOptec, or AMS Technologies is recommended to discuss custom configurations and performance specifications .
