Fiber-to-the-home (FTTH), which directly uses optical fiber to directly enter the communication line from the central office into the user’s home, has unparalleled advantages in bandwidth and can realize comprehensive access of various services.
The optical fiber in the drop cable adopts G.657A small bending radius optical fiber, which can be laid with a bending radius of 20mm. The ftth butterfly optical cable has the characteristics of small curvature radius, light weight and relatively good bending resistance.
According to the type of strength member, the drop cable can be divided into two types: metal strength members and non-metal strength members. The metal-strengthened drop cable can achieve greater tensile strength and is suitable for long-distance indoor horizontal wiring or short-distance indoor vertical wiring. The fiber optic cable of the non-metallic reinforcement adopts FRP as the reinforcement material, which can realize all non-metallic entry into the home, and has superior lightning protection performance, which is suitable for introduction from outdoor to indoor.
Models of metal-strengthened drop-wire optical cables are: GJXH, GJYXCH (self-supporting), non-metallic-strengthened drop-wire optical cable models are: GJXFH, GJYXFCH (self-supporting), indoor butterfly cable has 1 core, 2 cores, 4 cores Core and other specifications.
The outer sheath of the drop cable is generally made of PVC material or LSZH material. The flame retardant performance of LSZH material is higher than that of PVC material. At the same time, the use of black LSZH material can block ultraviolet erosion and prevent cracking, which is suitable for outdoor to indoor introduction.
KSD as a leading FOC manufacturer in China, We supplied to National Grid,cooperated with domestic design institutes,not only supplied to China National Grid, but also more than 10 foreign National Grid.we has our full range of optical fiber cable to more than 60+ countries, such as Ecuador, Peru, Colombia, Chile, Venezuela, Canada, Korea, Indonesia,Vietnam, Zambia, Nepal, Philippine, Bulgaria, etc.
