Flat Dublex

Description

Flat Dublex Cables are compact, dual-fiber optical cables designed for FTTH/FTTB networks, indoor–outdoor transitions and customer-premises connectivity. Their flat profile positions two optical fibers side-by-side, delivering excellent bending performance, easy handling and reliable transmission even in tight routing spaces. Because of their balanced structure and mechanical stability, flat dublex cables can serve as both drop cables and premises-level patch cables, making them a versatile solution for last-mile fiber infrastructure.

Ideal for telecom operators, ISPs, integrators and installers, flat dublex cables support fast, clean and efficient deployment across residential and commercial installations.

Performance Characteristics

Flat dublex cables offer a combination of mechanical strength and optical stability through the following design features:

1. Dual-fiber (2F) arrangement, optimized for redundancy or dual-service delivery

2. Parallel FRP or steel strength members for controlled tensile behavior and stable routing

3. G.657.A1/A2 bend-insensitive fibers, ensuring low-loss performance in tight indoor or façade-mounted pathways

4. Flat geometry that supports easy stripping, termination and connectorization

5. UV-resistant outer jackets for outdoor exposure in façade or short aerial runs

6. Optional LSZH sheathing when fire-safety compliance is required indoors

7. Smooth jacket surface minimizing friction during wall mounting or duct entry

8. High compatibility with mechanical connectors and pre-terminated assemblies

These characteristics make flat dublex cables well-suited for both drop applications and patch-cord environments.

Application Scenarios

Flat dublex cables are used in a wide range of FTTH and customer-premises installations, including:

1. Pole-to-home or façade-mounted FTTH drops

2. Residential and commercial building entry points

3. Indoor wall-mounted routing with tight bends

4. Customer-premises patching (ONT/ONU to outlet, cabinet connections, short interconnects)

5. MDU installations requiring compact dual-fiber access

6. Rural FTTH networks where strengthened flat cables support longer drop distances

With their simple structure and high bend performance, flat dublex cables adapt easily to mixed outdoor–indoor segments.

Design Advantages

Flat dublex cables provide several technical and operational benefits:

1. Compact and lightweight construction for easy handling and fast installation

2. Enhanced bend tolerance for corner routing and indoor mounting

3. Parallel strength members delivering reliable tensile performance

4. Excellent termination workflow, supporting both field-installable and factory-terminated connectors

5. Clean, symmetrical design ideal for patching and structured wiring

6. UV-stable outdoor jackets combined with LSZH indoor variants for hybrid usage

7. Dual-fiber configuration enabling main + backup services or multi-service delivery

These advantages help reduce installation time and improve overall network reliability.
