BFY400HS02 In Stock

The BFY400HS02 by ThorLabs is a bifurcated fiber bundle, a durable and high-performance optical fiber solution for a range of applications. Constructed from two high-grade optical fibers, encased in stainless steel tubing, the BFY400HS02 is designed to provide long-lasting and reliable service.

With a core size of Ø400 µm, the BFY400HS02 contains two high-OH fibers and has three cable ends that are terminated with SMA905 and FC/PC connectors. The stainless steel sleeves of the connectors on the breakout legs of the cable are engraved to indicate the fiber type in each leg, while 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. Measuring 2 m long from the common end to the split ends, the BFY400HS02 features two legs that are threaded through a sliding clamp, enabling the breakout length of the cable to be adjusted. The clamp can be locked in place by tightening the 5/64" (2 mm) hex setscrew, with a 5/64" (2 mm) hex key included with each bundle.

The BFY400HS02 is an excellent choice for applications where sources that provide even illumination across both fiber cores are required. It is best used with sources such as LEDs with a large emitter angle or white light sources, where the common end is used as the input. Additionally, the BFY400HS02 features three protective fiber caps that shield the connector ends from dust and other hazards, ensuring long-lasting and reliable performance.
