en.Wedoany.com Reported - Belden has introduced the PPC DiamonDrop single-fiber drop cable, designed for last-mile and drop segment broadband applications, suitable for outdoor aerial and underground infrastructure installations, aiming to simplify field preparation and enhance termination efficiency.

Against the backdrop of accelerating regional broadband deployment, especially in rural and underserved areas, installation teams face challenges in quickly connecting users, maintaining deployment consistency, and reducing rework. The DiamonDrop addresses these issues by optimizing the field cable preparation process without requiring changes to existing deployment standards or company operating procedures. Compared to traditional lightweight flat drop cables, this product offers enhanced operational convenience while maintaining compatibility with industry-standard connectors and common outdoor facility field practices.

This single-fiber cable features a proprietary core layout designed to provide exceptional handling characteristics during splicing and field preparation. Its core design allows technicians to cleanly strip the outer jacket without the need for specialized stripping tools when exposing the 900-micron tight-buffered fiber, reducing the risk of fiber damage. The mechanical design ensures compatibility with a variety of industry-standard connectors and optical hardware components, supporting standard field termination methods. The components are encased in a weather-resistant and UV-resistant protective jacket, capable of withstanding long-term environmental degradation in outdoor settings. The cable is suitable for both aerial and underground deployment, including underground conduit installation or direct burial; under the National Electrical Safety Code (NESC) heavy loading conditions, it can support aerial spans of up to 150 feet. The product series fully complies with RoHS Directive 2011/65/EU and offers production options compliant with the Build America, Buy America Act (BABA) for infrastructure projects.

Doug Jones, Vice President of Broadband Solutions Product and Innovation at Belden, stated that the cable platform is designed to eliminate cable preparation and termination challenges, which are among the most common complexities in last-mile fiber work. Jones noted that the core architecture enables deployment teams to perform field installations with greater quality confidence and consistency in both aerial and underground environments. This drop cable is positioned for FTTX outdoor aerial and underground deployment, serving telecommunications providers, rural broadband initiatives, and data infrastructure projects.

Fiber-to-the-Home (FTTH) drop cables are the final link in the optical distribution network, connecting the local distribution splice closure to the subscriber premises. Standard flat drop cables typically feature a rigid, tightly bonded outer polyethylene jacket reinforced by parallel dielectric or metallic strength members, such as fiberglass-reinforced plastic (FRP) rods. Traditional preparation requires technicians to use specialized tools to cut the jacket along the strength members to access the central loose tube, posing a risk of tool slippage. The clean-strip jacket geometry introduces a weak shear plane between the outer jacket and the internal 900-micron tight-buffer layer through co-extrusion manufacturing technology, allowing technicians to smoothly strip the jacket by hand. The 900-micron tight-buffer layer provides secondary mechanical protection for the 250-micron acrylate-coated silica fiber, making the core robust enough for direct termination using mechanical field-installable connectors, such as SC/APC or LC/APC quick connectors. Under NESC heavy loading conditions, the cable span must withstand the simultaneous effects of 0.5 inches of radial ice and a wind pressure of 4 pounds per square foot (at 0°F/-18°C). The internal FRP strength members are designed with precise tensile modulus to limit sag and control structural elongation, preventing mechanical stress from being directly transmitted to the internal glass core.
