Description

GJJV-1B6A2 Invisible Optical Fiber Cable

The GJJV-1B6A2 is an ultra-thin 0.9mm nylon tight-buffered indoor optical fiber cable designed for discreet, nearly invisible fiber deployments. Built with ITU-T G.657A2 bend-insensitive single-mode fiber, it delivers reliable optical performance even when routed around tight corners and through constrained pathways — making it the ideal choice for FTTH in-home wiring, MDU (Multi-Dwelling Unit) installations, and surface-mount applications where aesthetics matter.

Key Features

  • Ultra-Thin Profile: 0.9 ± 0.1 mm outer diameter — virtually invisible when surface-mounted along walls, baseboards, or ceiling corners
  • Bend-Insensitive G.657A2 Fiber: Macrobend loss ≤ 0.1 dB at 1550 nm (1 turn, 10 mm radius), enabling tight routing without signal degradation
  • Durable Nylon Outer Sheath: Transparent nylon jacket protects the fiber while maintaining a discreet appearance
  • Lightweight: Approximately 0.9 kg/km — easy to handle and install
  • Wide Operating Range: Reliable performance from -10°C to +50°C

Applications

  • FTTH in-home / in-building drop wiring
  • MDU (Multi-Dwelling Unit) fiber distribution
  • Surface-mount deployments along walls, baseboards, and moldings
  • Office and commercial building fiber-to-the-desk
  • Hotels, hospitals, and heritage buildings requiring minimal visual impact
