Thorlabs' Bifurcated Fiber Bundles, also known as fanout or Y-cables, are constructed from two high-grade optical fibers encased in stainless steel tubing for durability. We offer these bundles with seven fiber core sizes from Ø50 µm to Ø1000 µm. As shown in the table below, they are available with two high-OH fibers, two low-OH fibers, one high-OH and one low-OH fiber, or two ZBLAN ZrF

fibers. ZrF

fiber bundles are particularly advantageous for spectroscopy, as they offer exceptionally broad transmission from the UV into the mid-IR (285 nm - 4.5 µm).
All three ends of the cable are terminated with SMA905 or FC/PC connectors. SMA905 connectors are available for each fiber type and diameter. FC/PC connectors are available for high-OH fibers with a 200 or 400 µm core diameter. The stainless steel sleeves of the connectors on the breakout legs of the cable are engraved to indicate the fiber type in each leg. The sleeve of the common connector is engraved with the fiber core size and numerical aperture (NA).
One leg of each bundle contains both fibers before passing through a junction where the cable splits into two legs, each containing a single fiber. Cables with high-OH and/or low-OH fibers are 2 m long from the common end to the split ends, while cables with ZrF

fibers are 0.5 m long from the common end to the split ends. See the table below for a summary of the dimensions. The two legs are threaded through a sliding clamp so that the breakout length of the cable can be adjusted. The clamp can be locked in place by tightening the 5/64" (2 mm) hex setscrew. A 5/64" (2 mm) hex key is included with each bundle.
When using the common end as the input, these cables perform best when used with sources that provide even illumination across both fiber cores, such as LEDs with a large emitter angle or white light sources like Thorlabs'

Each patch cable includes three protective fiber caps that shield the connector ends from dust and other hazards. Bundles with SMA905 connectors include metal

dust caps;
