Indoor Ribbon Fiber Optic Cable Multi-Cores Mini Flat

4, 6, 8 & 12 Core GJFDBV Indoor Flat Ribbon Fiber Optic Cable

The GJFDBV Indoor Flat Ribbon Fiber Optic Cable is a high-density solution engineered for modern data centers, LAN backbones, and Fiber-to-the-Home (FTTH) deployments. This cable’s core feature is its optical fiber ribbon, where multiple fibers (4, 6, 8, or 12) are precisely arranged in a flat matrix. This design dramatically accelerates installation by enabling mass fusion splicing, significantly reducing labor time and costs. Encased in a flame-retardant LSZH jacket and reinforced with high-strength aramid yarn, the GJFDBV cable offers a compact, efficient, and safe solution for high-capacity indoor networking.

Key Features

• Ribbon Fiber Technology: Contains 4 to 12 color-coded fibers in a single ribbon, enabling rapid mass fusion splicing to connect all fibers simultaneously.
• Compact Flat Profile: The mini flat design allows for high-density packing in cable trays, ducts, and conduits, saving valuable space in crowded pathways.
• Easy Strippability: The ribbon’s matrix material is engineered for quick and clean removal, simplifying the preparation process for splicing or termination.
• Non-Metallic Strength Member: High-tensile aramid yarns serve as the primary strength member, providing excellent protection against pulling forces during installation while keeping the cable lightweight and fully dielectric.
• Multiple Fiber Types Available: Fully customizable with various fiber types, including single-mode (G.652.D, G.657.A1/A2) and multimode (OM3, OM4, OM5), to meet diverse network requirements.
• LSZH Safety Jacket: The standard Low Smoke Zero Halogen (LSZH) jacket ensures maximum safety in indoor environments by minimizing smoke and toxic gas emissions in case of fire.

Frequently Asked Questions (FAQ)

1. What is a ribbon fiber optic cable?

A ribbon fiber optic cable is a type of cable where multiple optical fibers are laid out parallel to each other and encapsulated in a plastic matrix, forming a flat, ribbon-like structure. This design facilitates connecting many fibers at once.

2. What is the main advantage of using ribbon cable?

The primary advantage is speed and cost efficiency during installation. Ribbon cables are designed for mass fusion splicing, a process that splices all 12 fibers (or fewer) in a ribbon simultaneously, drastically reducing connection time compared to single-fiber splicing.

3. What does GJFDBV stand for?

GJFDBV is a model designation. In general, ‘GJ’ signifies an indoor cable, ‘F’ indicates a non-metallic strength member (like aramid yarn), ‘D’ refers to a fiber ribbon structure, ‘B’ means it’s a flat cable, and ‘V’ denotes a PVC jacket (though LSZH is also a common option).

4. Where is this type of cable typically installed?

This cable is designed for indoor environments with high fiber density requirements, such as data centers, telecommunication rooms, LAN backbones, and for distributing fiber vertically within buildings (FTTH MDU applications).

5. Can this cable be terminated with standard connectors like LC or SC?

Yes, but it requires a fan-out kit. The ribbon is first stripped, and then the individual 250µm fibers are threaded into a fan-out kit’s color-coded tubes, which build them up to a 900µm diameter suitable for standard connector termination.

6. What is mass fusion splicing?

Mass fusion splicing is a technique that uses a specialized machine to align, fuse, and protect an entire ribbon of fibers (e.g., all 12 fibers) in a single, automated process, offering huge time savings over splicing fibers one by one.

7. Is this cable plenum-rated?

This standard GJFDBV cable with an LSZH or PVC jacket is typically Riser-rated (OFNR). A Plenum-rated (OFNP) version would require a different jacket material to meet stricter fire codes for plenum air spaces. Custom plenum versions can be manufactured upon request.

8. What’s the difference between PVC and LSZH jackets?

The key difference is fire safety. A standard PVC jacket can release thick, toxic smoke when burned. An LSZH (Low Smoke Zero Halogen) jacket emits very little smoke and no toxic halogen gasses, making it the safer and often required choice for enclosed indoor spaces.

9. What fiber types are available for this cable?

We can manufacture this cable with virtually any fiber type, including single-mode OS2 (G.652.D, G.657.A2) and multimode OM3, OM4, and OM5 to support various network speeds and distances.

10. How does this cable save installation time?

It saves time primarily through mass fusion splicing. Splicing 12 fibers individually could take up to an hour, while a mass fusion splice of a 12-fiber ribbon can be completed in just a few minutes, including preparation.

11. What is a fan-out kit used for with ribbon cable?

A fan-out kit is used to transition from the high-density ribbon to individual, more robust fibers for connectorization. It separates the 250µm fibers from the ribbon and protects each one inside a color-coded 900µm buffer tube.

12. Why is aramid yarn used as a strength member?

Aramid yarn (similar to Kevlar®) offers an extremely high tensile strength-to-weight ratio. It protects the delicate optical fibers from pulling forces during installation without adding metallic components, which keeps the cable dielectric and immune to EMI.

13. Is the ribbon’s matrix material easy to remove?

Yes, the material binding the fibers into a ribbon is specifically designed to be ‘strippable.’ Using a special tool, an installer can quickly and cleanly remove the matrix to expose the individual fibers for splicing or termination.

14. Can I get this cable with custom printing on the jacket?

Absolutely. As the manufacturer, we offer custom printing on the cable jacket, which can include your company name, project codes, or sequential length markings to simplify installation and inventory management.

15. Why choose a flat cable design for indoor use?

A flat design is highly space-efficient, allowing more cables to fit into crowded cable trays and conduits. It also prevents twisting and can make cable management and routing simpler compared to round cables.
