Available in 1-2 Fibers (with Standard Single Mode G.652.D Fiber)
Application
Fiber To The Home Technology represent an attractive solution for providing high bandwidth from central office to residences and to small and medium sized businesses. It is cost effective; its simple cable structure provides ease in the network operations.
The cable is designed for Indoor Applications in FTTH configurations with low bending sensitivity fiber; it provides high bandwidth and excellent communication transmission characteristics. Small bending fiber’s fatigue lifetime is several hundred times longer than other standard single mode fibers.
1. Cable Construction
1.1. Cable Design
The optical fibers are placed in the center, Two Parallel Strength Members (Steel Wire or FRP) is placed at the two sides, the cable is then completed with LSZH sheath having a Notch to tear the cable and expose the fibers.
- Fiber: The Cable is based on
- Single Mode Fiber as per ITU-T G.652.D Specs – 9/125
- Also available in ITU-T G.657 – 9/125 Bend Insensitive Fiber
- Fiber Color:
- Any combination (Blue-Orange or Blue-White or as requested)
- Strength Member:
- Fiber Reinforced Plastic or Steel Wire is used as Strength Member.
- Sheaths:
- Sheath of Low Smoke Zero Halogen and Flame Retardant
- Color: White, Ivory, Black or as desired.
- Cable Size:
- 2mm (±0.1mm) x 3mm (±0.1mm)
- Average Cable Weight:
- 9.6kg/km
