Fiber-to-the-home (FTTH) directly uses optical fiber to connect communication lines from the central office directly to users' homes. It has unparalleled advantages in bandwidth and can realize comprehensive access to multiple 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. It is suitable for entering the house through pipes or open wires in the building. ftth butterfly optical cable has the characteristics of small curvature radius, light weight and relatively good bending resistance.
Drop optical cables can be divided into metal reinforcements and non-metal reinforcements according to the type of reinforcements. Sheath optical cables with metal reinforcements can achieve greater tensile strength and are suitable for long-distance indoor horizontal wiring or short-distance indoor vertical wiring. The non-metal reinforcement sheath optical cable uses FRP as the reinforcement material, which can achieve all-non-metal home entry, has excellent lightning protection performance, and is suitable for introduction from outdoors to indoors.
FTTH drop optical cable models with metal reinforcements include: GJXH, GJYXCH (self-supporting), non-metal reinforcement leather optical cable models include: GJXFH, GJYXFCH (self-supporting), indoor butterfly optical cables include 1 core, 2 core, 4 core Core and other specifications.
The outer sheath of drop optical cables 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 black LSZH material can block ultraviolet erosion and prevent cracking, and is suitable for introduction from outdoor to indoor.
