High Power Under Tight Bends

Laser-induced Damage to Large Core Optical Fiber by High Peak Laser Power
Laser-induced Damage to Large Core
Optical Fiber by High Peak Laser Power

Adapted from manuscript by Dr. Xiaoguang Sun and Dr. Jie Li | rewrite by Anthea Croghan

As medical applications are demanding optical fibers to transmit with increasingly higher peak powers and smaller bend diameters, it has become necessary to test and develop fibers that can perform under these strenuous conditions. A study recently completed by Dr. Xiaoguang Sun and Dr. Jie Li of OFS examined laser damage to large core multimode glass optical fibers from high peak laser power, providing important insight into the damage mechanism for a particular failure mode. A two-point bend tester was used on fiber samples prepared with polymer coatings, having different refractive indices. It was found that peak power was one of the main determining factors in performance among the samples. Polymer coatings with lower refractive indices were found to significantly improve fiber resistance to bending while transmitting. Read More…

cardiology and so much more!

Optical fibers are successfully used in various areas of medicine, including urology, general surgery, ophthalmology, cardiology, endoscopy, dentistry and medical sensing [1 – 4]. Prior to use inside a human body the fiber must be sterilized to ensure it is free of microorganisms such as fungi, bacteria, and virus or spore forms. Read More…

Standards Update: Bend-Insensitive Multimode Fiber

Enterprise Networks
Enterprise Networks

Standardization of bend-insensitive multimode fiber (BIMMF) has been a very active area within the Telecommunications Industry Association (TIA) and the International Electrotechnical Commission (IEC). Since the start of the year, more than a dozen contributions on the topic have been reviewed in the TIA working group TR-42.12 “Optical Fiber and Cable.” Read More

Does Optical Fiber Have You Tied in Knots?

Tied in Knots

At the upcoming PowerGen trade event in Orlando (December 11-13, 2012), OFS is proud to demonstrate HCS® (Hard Clad Silica) optical fiber, cable and field termination technology. Unlike telecommunications grade optical fibers, you can tie our products in knots. While we don’t recommend this in practice, seeing it first hand will help you understand just how rugged these industrialized glass optical fibers are. Read More…

The inquiry arrived through our sales guy on the west coast. A simple request with little detail and no hint at what the future would bear.

“The customer is thinking about using fiber optics as a data link and they don’t have complete control over the operating environment. Can we help them out?”

“Well, we may have a solution but we’ll need to know a bit more about the application before we can make any recommendations. Can you describe the operating conditions with more detail?” Read More…

When most people hear the term & "fiber optics" they naturally envision hair-thin strands of glass, the enablers of today’s high speed telecommunication and global internet. While that’s all true, it’s really just the beginning where the technology of fiber optics is concerned. In the Specialty Photonics Division of OFS we work in a world that extends well beyond telecommunications. Read More

Why Optical Fiber for the Medical Industry?

Even though the first use of lasers in medicine was reported by Goldman in 1962-and then in 1963 for experimental cardiovascular plaque ablation-it is the Aesthetic and Ophthalmic applications that historically pushed the use and adoption of photons in medicine. In addition to invasive and non-invasive cosmetic treatments and ophthalmic therapies, urology is another mature market today using lasers and optical fiber probes. In this market lasers and optical fibers are used in transurethral laser therapy for benign prostatic hyperplasia (BPH) and kidney stone ablation. Read More…
