Bend-Optimized Fiber

OFS bends the rules of optical fiber by offering a complete portfolio of bend-optimized technologies that meet the most demanding requirements of communications, fiber-to-the-home (FTTH), cable television, medicine, industry and other applications. As a leading designer of innovative fiber solutions, OFS Laboratories has a long tradition of developing optical bend capability and transforming industry-leading discoveries into real-world products. In fact, Bell Labs optical fiber research group (now OFS Labs) invented bend-optimized single-mode fibers in 1984. OFS creates its bend-optimized fiber designs to provide optimal bending support for each application.
