Thorlabs, TYCLON, and MFOPTEX are key manufacturers of two-core bundled optical cables, offering customizable fiber types, core sizes, and connector options.

Thorlabs

Thorlabs produces bifurcated fiber bundles (two-core cables) constructed from high-grade optical fibers encased in stainless steel tubing for durability. They offer a variety of fiber types including solarization-resistant, high-OH, low-OH, and ZBLAN fibers, with core sizes ranging from 50 µm to 1000 µm. The cables are terminated with SMA905 or FC/PC connectors, and lengths vary depending on fiber type (2 m for standard fibers, 0.5 m for ZBLAN). These bundles are suitable for spectroscopy and other applications requiring broad wavelength transmission from UV to mid-IR (285 nm - 4.5 µm) (Thorlabs) .

TYCLON

TYCLON manufactures bundled 2-core fiber optic cables for both single-mode (SM) and multi-mode (OM1–OM5) applications. They provide a wide selection of connectors including SC, LC, ST, FC, MU, and SMA905, and allow custom cable lengths and quantities. TYCLON's two-core cables are ideal for bidirectional communication, and they also offer cord-bundle and flat-type configurations. Non-standard configurations can be requested to match specific application requirements (TYCLON) .

MFOPTEX

MFOPTEX offers fiber bundles composed of 2 or more optical fibers, with options for precise fiber arrangements, anti-reflective coatings, and customized layouts. Their bundles can be used to split or combine light paths, adjust beam shapes, and transmit light over a wide wavelength range from deep UV to near IR. MFOPTEX supports customized designs to meet specific equipment or experimental requirements, making them suitable for high-precision optical applications (MFOPTEX) .

Considerations for Selection

When choosing a two-core bundled optical cable, consider the following:

• Fiber type: Single-mode for long-distance, high-speed communication; multi-mode for short-distance, high-bandwidth applications.
• Connector type: Ensure compatibility with your equipment (SC, LC, ST, FC, MU, SMA905).
• Core size and numerical aperture: Affects light transmission efficiency and coupling.
• Cable length and flexibility: Customizable to fit installation requirements.
• Spectral range: Choose fibers suitable for your wavelength requirements (UV, visible, NIR, or mid-IR). These manufacturers provide both standard and customizable two-core bundled optical cables, making them suitable for a wide range of scientific, industrial, and communication applications.
