GJFXTKV indoor outdoor fiber optic cable is a versatile optical cable designed for both indoor and outdoor applications. With a compact structure and excellent environmental resistance, it eliminates the need for transition joints between outdoor and indoor cabling.
This dual-purpose cable is widely used in FTTH networks, building entry applications, and distribution systems where reliability and installation efficiency are critical.
What is GJFXTKV Cable?
GJFXTKV is a central loose tube indoor/outdoor fiber optic cable, where optical fibers are housed inside a protective loose tube filled with water-blocking compound.
It is designed to:
- Resist moisture and environmental stress
- Maintain flexibility for indoor routing
- Provide reliable performance in hybrid installations
Typically, it supports 2–12 fibers and includes high-strength reinforcement materials such as E-glass or FRP.
Key Features
- Indoor & outdoor dual-use design
- Central loose tube structure
- Waterproof and moisture-resistant construction
- Small diameter and lightweight
- High tensile strength with reinforcement members
- LSZH / PVC / PE jacket options
- Fiber count: 2–12 cores
The loose tube is filled with water-resistant material to prevent moisture ingress and ensure long-term reliability.
Why Use Indoor/Outdoor Fiber Cable?
Traditional installations require separate cables:
- Outdoor cable → up to building entry
- Indoor cable → inside building
This creates:
- Extra splicing points
- Higher installation cost
- Increased signal loss risk
👉 GJFXTKV solves this by combining both functions.
Indoor/outdoor cables are designed to combine environmental resistance with indoor safety requirements, avoiding transition points.
Applications
- FTTH (Fiber to the Home)
- Building entry cabling
- Indoor/outdoor distribution networks
- Telecom and access networks
- Aerial and duct installations
GJFXTKV is widely used in FTTH systems to connect outdoor networks directly into buildings without additional cable transitions.
