Description
What it is
A fiber optic drop cable is the final link between a service provider’s distribution network and the subscriber. This series is built around G.657 bend-insensitive fiber for tight spaces and in-building pathways, with structures ranging from indoor FRP to outdoor steel-reinforced and figure-8 self-supporting aerial designs.
Where it’s used
- FTTH/FTTP last-mile introductions from distribution points to ONTs/routers
- Indoor runs (hallways, shafts, MDU risers) and duct entries
- Aerial spans using figure-8 self-supporting variants
- Outdoor-to-indoor transitions requiring compact routing and flame-retardant jackets
Construction highlights
- Fiber: G.657 (A1/A2) bend-insensitive, 1F/2F/4F typical (≤12F optional)
- Strength: parallel FRP or steel; steel messenger for figure-8 aerial
- Jackets: LSZH or flame-retardant PVC for indoor; PE for outdoor/weather
- Groove/Easy-peel geometry for fast access, field termination, and maintenance
- Compatibility: supports field connectors (fast-connect/mechanical) and pre-terminated assemblies
Termination options (Splice or Connector)
- Fusion splice: lowest loss & reflection for permanent joints
- Mechanical splice/field connector: fast, tool-light installs and easy service access
Choose splice for fixed layouts; choose connectors where testing or future re-arrangement is expected.

Key Benefits
- Bend-insensitive G.657 fiber supports tight pathways with minimal signal penalty.
- Multiple structures (FRP/steel/figure-8/armored) cover indoor, duct, and aerial installs.
- Easy-peel groove design speeds access, splicing, and field connectorization.
- Indoor flame-retardant (LSZH/FR-PVC) and outdoor UV/PE jackets meet code and environment needs.
- Compact, lightweight profiles simplify last-mile routing and reduce installation time.
- Pre-terminated or field-terminated options to match deployment strategy and OPEX.
