Fiber Optic Patch Cables

Not every patch cable is created equally. Our partner, Gulf Photonics, takes pride in manufacturing the highest quality, most durable patch cables out there. If you need your cables to perform right the first time, every time, don’t take chances with cheap imitations, call us for distribution today.

Our standard patch cables come with your choice of Broadband (200-2200nm) or UV/SR fiber (200-1100nm). If you have a need in the Deep UV (190nm and below), contact us to learn more about our Enhanced Solarization Resistant (ESR) product line.

Custom lengths, fiber types, connectors, and cable construction are also available, please inquire for more information and a quotation.

Bifurcated Cables

Our bifurcated cables are perfect for routing of light to and from a sample, for illuminating one sample with two light sources, or for collecting light to be routed to multiple detectors. Our standard cable lengths are from 1-10 meter common legs, with 0.5 meter breakout legs. They are terminated with high-quality proprietary Gulf Photonics SMA-905 connectors, and come standard with your choice of silicone monocoil or fully expanded stainless steel jacketing.

Custom Termination

Sometimes off-the-shelf just doesn’t cut it. Our partner, Gulf Photonics, has made it easy to help our customers find the exact solution they need to fit their application. We work with wide variety of fibers, connectors and sheathing options, which means whether you’re driven by cost or performance, we’ve got a solution for you. Gulf’s design engineering team can help define your requirements, develop documentation and select the best materials. Unlike many of our competitors, we’re happy to tackle low-volume and development projects.

Borosilicate Fiber Bundles

Borosilicate optical fiber is an efficient, effective method for moving light when reliability and cost are your key concerns. Our partner, Gulf Photonics, has been drawing its own borosilicate fibers for over 20 years. This experience ensures that we can custom configure bundles to fit any application. From complex medical applications to custom probes, we have seen it all. Whether your application needs just a few fibers or has a high degree of complexity, our team can make it happen.

Many application needs can be met with less expensive borosilicate glass fiber assemblies. This fiber transmits well in the visible, from 380-1700nm. Borosilicate glass fiber is typically small in diameter (<100um), with a thin cladding and no buffer. This allows it to be more flexible and have a very tight bend radius – perfect for small spaces.

The high core to cladding ratio makes borosilicate fiber ideal for tight packing into bundles, as seen to the right. Bundles can contain hundreds to thousands of single fibers, maximizing light collection and transmission, and offering valuable redundancy in case of fiber breakage.

Borosilicate fiber also boasts a larger numerical aperture, making it well-suited to spectroscopy and sensing applications requiring efficient light collection. Bundle geometries can be customized to the application, with each termination uniquely matching the object to which it is mated – a narrow slit, a round LED, or a series of legs routed to different sampling locations.

We have 35um and 50um diameter fiber available, with numerical apertures of 0.55 and 0.66.

The large number of fibers used in a borosilicate fiber bundle makes it ideal for light manipulation. A multi-legged assembly can be built such that the input from each leg is evenly distributed across the bundle area (randomized), thus mixing light from different sampling points (or sources of different wavelength) without the use of a diffusing element and its associated attenuation. Conversely, the light can be carefully mapped, with input from each leg routing to a different part of the bundle or slit.  Contact us if you think borosilicate may be an option for your application.
