Description
DCFA optical cable features colored optical fibers placed in a loose tube made of high-modulus, hydrolysis-resistant material filled with thixotropic water-blocking gel. A non-metallic strength member (FRP) serves as the central core, around which the loose tube and filling rope are helically twisted to form a compact, circular cable core. The core is protected by water-blocking yarn and longitudinally wrapped with water-blocking tape, followed by a layer of coated aluminum tape for additional protection. Finally, a polyethylene sheath is extruded to complete the cable, delivering excellent performance and reliability in diverse environments.
Feature
Cross-section Diagram
- Good mechanical performance and excellent temperature stability.
- Loose tube material offers high hydrolysis resistance and outstanding pressure resistance.
- Special water-blocking yarn inside the loose tube ensures crucial protection for optical fibers.
- Tight cable structure effectively prevents tube shrinkage.
- Coated aluminum tape layer enhances moisture resistance.
- Polyethylene sheath provides excellent ultraviolet (UV) radiation resistance.
Application Scenario
1. Telecommunications Networks
- Backbone and long-distance optical communication networks.
- Metropolitan area networks (MANs) for urban data transmission.
- Fiber-to-the-home (FTTH) and fiber-to-the-building (FTTB) installations.
2. Data Centers
- High-density fiber installations for interconnectivity and fast data transfer.
- Supporting large-scale data center network expansions.
3. Outdoor Installations
- Suitable for aerial, duct, or direct burial applications in outdoor environments.
- Ideal for regions with high UV exposure due to the polyethylene sheath's UV resistance.
4. Energy and Utilities
- Smart grid networks and power system monitoring.
- Renewable energy systems such as solar and wind farms for data communication.
