Thorlabs’ line of high-quality fiber optical bundles consists of either 7 or 19 high-grade optical fibers in a round configuration combined in an SMA 905 connector. Versions are available with either low-OH or high-OH fibers. Fibers with Ø200 μm cores are used in the bundles of 19 fibers and feature a Ø1.3 mm bundle aperture. In contrast, fibers with Ø550 μm cores are used in the bundles of 7 fibers and feature a Ø2.0 mm bundle aperture. The Ø1.3 mm fiber bundle has a smaller bend radius than the Ø2.0 mm bundle. However, the Ø2.0 mm bundle has a larger diameter allowing more light to travel along it. These fiber bundles are primarily designed for coupling to light sources and therefore the fibers are not in the same orientation at each end, and each item may have some variation in the relative position of the fibers in the connector. For increased durability, these cables incorporate stainless steel protective tubing (FT05SS).
The OSL1-SMA Lamp Adapter allows our OSL1 High-Intensity Halogen Light Source to be coupled into our fiber bundles for microscopy and illumination applications.
Each patch cable includes two protective caps that shield the connector ends from dust and other hazards. Additional CAPM Rubber Fiber Caps and CAPMM Metal Threaded Fiber Caps for SMA-terminated ends are also sold separately.
Custom fiber bundles are available upon request. We can also make custom bifurcated fiber bundles, where one common connector is split into two or more connectors. Please contact Thorlabs' Tech Support at email@example.com.

Custom Fiber Bundles
Thorlabs is pleased to offer custom straight and fanout fiber bundles with random or mapped fiber configurations. The table to the bottom right outlines some of our current bundle production capabilities. We are in the process of expanding our bundle production capabilities, so don't hesitate to inquire if you do not see the bundle that you require described here.
Some custom bundles will require techniques outside of our usual production processes. As a result, we cannot guarantee that we will be able to make a bundle configuration to fit the requirements of your specific application. However, our engineers will be happy to work with you to determine if Thorlabs can produce a fiber bundle that fulfills your needs. To receive a quote, please provide drawing or draft of your bundle configuration.
Our cable engineers are available to help you design a bundle for your application.
