Skeleton Unit Optical Cable
Skeleton optical fiber ribbon cable has the characteristics of high optical fiber density, small outer diameter saving pipeline resources, good lateral pressure resistance, stable structure, convenient connection, no filling grease, and environmental protection. The skeleton type optical cable comprises a central skeleton and a peripheral skeleton; the peripheral framework is embedded with optical fibers in a closed pre-wrapping mode and continuously wrapped on the central framework in a wrapping mode according to a preset pitch; the pitch value of the. FTTX can be divided into 4 modes: FTTC, FTTN, FTTP and FTTH. In the FTTH access mode, the feeder section and distribution section of the access network currently use three types of optical cables: loose cable, tight cable, and skeleton ribbon cable.
