AccuCore HCF™ Optical Fiber Cable is the world’s first terrestrial hollow-core fiber (HCF) cable solution. Light travels about 50% faster in a hollow core optical fiber compared to the solid silica core of conventional fiber. Consequently, light transmitted in a hollow-core fiber arrives 1.54 microseconds faster for each kilometer traveled compared with conventional optical fiber.

The AccuCore HCF Optical Fiber Cable solution includes indoor/outdoor cable and termination with standard connectors, which are fusion-spliced to the patented photonic bandgap hollow-core fiber. OFS also offers installation services and both passive and active component selection to meet customer requirements.  AccuCore HCF optical fiber cable has been successfully deployed, carrying live traffic in several networks.

This latest development from OFS was presented as a postdeadline paper on March 12, 2020 at the Optical Fiber Communication Conference and Exhibition (OFC) held in San Diego.  OFC postdeadline papers represent the latest and most advanced technical achievements in the field. The paper reported error-free transmission of direct-detection 10 Gb/s DWDM signals over 3.1 km of cascaded cabled HCF. This is the first time that transmission results in a cabled HCF have been reported.  That white paper is available here.
