FTTH Drop Cable Self-supporting Aerial Black Sheath

The self-supporting aerial FTTH drop cable with black sheath is a special outdoor overhead laying optical cable developed for long-distance outdoor user access and cross-street, cross-yard wiring scenarios, integrating self-supporting mechanical structure and outdoor weather resistance performance. The most prominent advantage of this cable is its built-in self-supporting tensile structure, which omits the need for additional steel wire ropes and fixing supports during aerial laying. It can be directly suspended and fixed between utility poles, buildings and other overhead points, greatly simplifying the construction process, shortening the construction cycle, and reducing the overall engineering cost of outdoor FTTH access wiring.

The cable is equipped with a high-performance black weather-resistant outer sheath, which is specially modified to resist ultraviolet radiation, high temperature aging, low temperature brittleness and rain erosion. Long-term exposure to outdoor sunlight, wind and rain, high temperature in summer and low temperature in winter will not cause sheath cracking, aging, fading or performance degradation, effectively protecting the internal optical fiber and tensile components from external environmental erosion. The internal tensile unit adopts high-strength galvanized steel wire or high-performance fiber reinforcement, which has strong tensile strength and wind resistance, and can resist the impact of strong wind, snow and hail in outdoor open-air environment, ensuring the stability of overhead laying for a long time.

This self-supporting aerial FTTH drop cable is widely applicable to outdoor network access scenarios such as rural household fiber access, urban community remote building wiring, suburban factory and villa area optical network layout. Its lightweight self-supporting structure avoids the heavy installation of traditional overhead optical cables, and the black sheath also has good dustproof and anti-fouling performance, maintaining a neat and beautiful laying effect. With stable optical transmission performance, strong mechanical adaptability and excellent outdoor durability, it solves the wiring difficulties of scattered outdoor users and long-distance spanning laying, and is an essential core product for outdoor FTTH access engineering of communication operators.
