Dublex Cables

Description

Dublex Drop Cables (2F drop cables) are engineered for FTTH and FTTB networks that require a compact, flexible and reliable dual-fiber connection between distribution points and customer premises. With two optical fibers positioned in a flat or round structure, these cables support dual-service provisioning, redundant paths or parallel routing within the same drop segment. Thanks to their excellent handling characteristics and high bend performance, dublex drop cables can also function as premises-level patch cables, providing a versatile solution for both outside plant and indoor connectivity needs.

Designed for telecom operators, ISPs, deployment contractors and system integrators, these cables deliver a stable optical link across the entire last-mile segment — from aerial spans to building entry and final in-home connection points.

Performance Characteristics

Dublex drop cables combine optical stability with mechanical strength, featuring:

1. Dual-fiber (2F) configuration for redundancy or multi-service applications

2. Flat or round duplex profiles suitable for patching, indoor routing and outdoor installations

3. Parallel FRP or steel strength members for controlled tensile behaviour in both drop and patch environments

4. G.657.A1/A2 bend-insensitive fibers, ensuring reliable performance in tight wall corners, customer premises and rack-mount termination

5. UV-resistant PE jackets for outdoor exposure

6. Optional LSZH sheathing for indoor patch cord use or indoor–outdoor transitions

7. Excellent compatibility with mechanical connectors, pre-terminated solutions and optical outlets

This construction supports efficient termination and low-loss performance from distribution tap to customer premises equipment (CPE).

Application Scenarios

Dublex drop cables are designed for a broad spectrum of FTTH/FTTB deployment environments, including:

1. Pole-to-home aerial routes

2. Façade-mounted pathways for residential and MDU buildings

3. Building entry points and indoor wall routing

4. Rural broadband networks requiring extended drop lengths

5. Dual-service delivery (e.g., Internet + IPTV, primary + backup link)

In addition, thanks to their compact profile, bend-optimized fibers and strength-balanced structure, dublex drop cables can function as premises-level patch cords. When produced with LSZH or indoor-rated jackets, they can be used for:

1. ONT/ONU-to-wall outlet patching

2. Indoor cabinet-to-distribution frame connections

3. Equipment room interconnects

4. Rack-to-rack patch links for FTTH distribution points

This makes the cable a multi-purpose solution capable of bridging the gap between outdoor drop requirements and indoor patching needs.
