Considered the world's first terrestrial hollow-core fiber (HCF) solution, details of AccuCore OFS's HCF optical fiber cable, the manufacturer's latest HCF product, were presented as a post-deadline paper on March 12 at OFC 2020 in San Diego. OFC post-deadline papers represent the latest and most advanced technical achievements in the field of optical communications technology.
As OFS noted, light travels approximately 50% faster in a hollow core compared to a solid silica core in conventional optical fiber. Consequently, light transmitted in a hollow-core fiber arrives 1.54 microseconds faster per kilometer traveled compared to conventional optical fiber.
The document reported error-free transmission of 10 Gb/s direct-sensing DWDM signals over 3.1 km of cascaded wired HCF. This is the first time transmission results have been reported over a wired HCF, the manufacturer noted.
Key applications for AccuCore HCF include: high-frequency trading; high-performance computing; 5G X-haul mobile networks; and interconnection within the data center.
