OFS

At work and at home, the rapid and precise transmission of data, voice, and video information has become an essential part of our daily lives. A vital link information technology is the path through w Optical fiber is the most advanced transmission medi At OFS, we've been meeting global demand for world-class optical fiber since 2001. In fact, our heritage dates back to the earliest days of the industry, when Spectran Corporation was founded in 1981 in Sturbridge, Massachusetts. OFS multi-mode fiber products are used primarily for data communications in data centers, Our 50-micron laser-optimized products, known as laser wave fibers, are designed for maxim The first step in manufacturing our multi-mode fiber is the creation of a solid glass rod called a preform. In our patented modified chemical vapor deposition process, ultra-pure chemicals are introduced into a synthetic silica glass tube. As a special torch moves along the rotating tube, w The soot is heated and fused into a t Layer by layer, the MCVD process creates a precise waveguide profile. Also known as the refractive index profile, it's required for laser-based communication systems. After these layers are deposited, the tube is collapsed into a solid rod or preform by increasing the temperature of the flame and decreasing the speed of the torch. Finally, the preform is analyzed to measure its refractive index and core diameter. The preform is converted into optical fiber in a process called fiber draw. First, the preform is lowered into a Tightly controlled temperatures approac Then, gravity takes over, allowing the molten tip to free fall, drawing a throughout the draw process, the fiber diameter is controlled to 125 microns, wit A laser-based diameter gauge samples the fiber more than a thousand times a second, ensuring that precise dimensions are maintained. Before the fiber is put onto winding dr Our Flex10 coating protects the pristine surface of the fiber from the environment and makes the fiber easier to handle. Our fibers are available with 245 micron or 500 micron coating options. After the preform draw, the fiber goes to test and measurement. Here, The fiber must prove to have a tensile strength of at least 100,000 pounds per square inch before it is wound onto the spool. A series of optical tests are conducted on every fiber. A device called an OTDR is used to measure attenuation or loss of optical power. The fiber is also tested for bandwidth, or the information carrying capacity of the fiber, the n Our laser wave fiber is designed for use at Its bandwidth must be verified using a measurement called differential mode delay, or DMD. T DMD measurement also provides vital process control feedback for the MCVD process. Geometric testing includes tests for core, clad and coating diameter, non-circularity and core to clad offset. Tight tolerance control of these parameters ensures minimal splice and connecturization losses. Be Every employee is trained to ass At OFS, these are the words we live by. They empower us to respond quickly, accurately and creatively to the challenges of our customers. As the transmission requirements of the information age continue to grow, OFS will be there, providing the latest solutions to meet communication challenges in the 21st century.
