Distribution Tight Mini Cable GJFJV
- Product Detail
- Specification
GJFJV distribution tight buffer fiber optic cable is a compact and flexible indoor cable designed for reliable optical communication and easy termination. Built with 900μm tight-buffered fibers and reinforced with aramid yarn, it offers excellent mechanical strength and stable performance.
This mini round cable is widely used in indoor distribution, patch cord production, and equipment interconnection in data centers and telecom networks.
What is GJFJV Cable?
GJFJV is a tight-buffered distribution fiber optic cable where each fiber is protected by a 900μm buffer layer and surrounded by aramid yarn strength members.
This structure allows:
- Easy stripping and termination
- High flexibility for indoor routing
- Reliable performance in short-distance communication
Tight-buffered cables are typically smaller, more flexible, and ideal for indoor installations compared to loose tube designs.
Key Features
- 900μm tight-buffered fiber structure
- Aramid yarn (Kevlar) strength member
- Small diameter and lightweight design
- Easy stripping and connector termination
- Available in simplex, duplex, and multi-core
- Jacket options: PVC / LSZH / OFNP
- Excellent mechanical and environmental performance
The tight buffer design enables fast installation and simplifies termination processes.
Cable Structure
Typical GJFJV cable structure includes:
- Optical fiber (SM or MM)
- 900μm tight buffer coating
- Aramid yarn reinforcement
- Outer sheath (PVC or LSZH)
This design ensures strong tensile performance and protects fibers during installation and operation.
Applications
- Indoor distribution cabling
- Fiber optic patch cords and pigtails
- Data centers and server rooms
- Equipment interconnection
- LAN and telecom networks
GJFJV cables are widely used for patch cords and equipment connections due to their easy termination and flexibility.
FAQ Section
What is GJFJV cable used for?
