FTTH Drop Cable

The page will come soon!In the optical fiber access project, the indoor wiring close to the user is the most complex link. The bending performance and tensile performance of conventional indoor optical cables can no longer meet the needs of FTTH (fiber to the home) indoor wiring, while the cable adopts fiber with smaller bending radius, soft and light materials are widely used in access networks like drop cable (for indoor wiring), such as G.657A fiber, which can be laid with a bending radius of 20mm and is suitable for entering homes in the building through pipes or open wires.


The drop cable can be divided into single-core, dual-core, or four-core structures. The cross-section is figure-8 or butterfly shape. The optical fiber is located in the geometric center of the 8-shaped shape, and two parallel non-metallic reinforcements (FRP) or metal reinforcement members on both sides, and then finally squeeze black or colored polyvinyl chloride (PVC) or low-smoke halogen-free material (LSZH, low-smoke, halogen-free, flame retardant) sheath.


With the different application scenarios, there are now many types of FTTH drop cables.


  • Special bend-resistant fiber provides greater bandwidth and enhances network transmission performance;
  • Two parallel FRP or metal reinforcements make the optical cable have good compression resistance and protect the optical fiber;
  • Optical cable has simple structure, light weight and strong practicability;
  • Unique groove design, easy to peel off, easy to connect, simplifies installation and maintenance;
  • Low-smoke, halogen-free, flame-retardant polyethylene sheath or flame-retardant PVC sheath, environmentally friendly.
  • It can be matched with a variety of field connectors and can be terminated on site.


  • Used for indoor wiring, end users use cables directly;
  • For fiber optic cable introduction into buildings;
  • Used for user indoor wiring in FTTH.
  • Shaft, building wiring
