摘　　要：典型产品 GYTA 金属加强构件、松套层绞填充式、铝-聚乙烯粘结护套通信用室外光缆 产品性能特点：光纤传输损衰减小、色散低。合理的设计及精确的控制松套管中光纤的余长及成缆方式。使光缆具有优良的机械性能和环境性能。光缆结构紧凑。采用SZ屡绞结构．易分支．保证光缆在恶劣的环境下，光纤不受到应力。加强件外和缆芯内充满阻水油膏．确保了光缆全截面阻水。复合铝带双面涂塑．并于PE护套紧密粘结，保证光缆的径向防潮。确保了光缆使用寿命。Outdoor optical cables for communication purpose with metal-reinforced components, filling mode by loose tube layer stranded, and laminated aluminum polyolefin sheath.Product property： minimized transmission attenuation and dispersion with rational design and accurate control of excessive length as well as cable-forming mode of the optical cable inside the loose tube so as to guarantee superior mechanic and environmental performance. The tight structure of the optical cable adopts SZ layered winding mode with easy branching to ensure that optical cables are not subject to stress under harsh environment. Between reinforced components and cable cotes ,are filled with water-resistant ointments so as to guarantee a full cross-sectional water resistance of the cables. Composite aluminum bands are plastically coated on both sides and also tightly connected to PE sheaths to ensure radial anti-dampness which would possibly bring along a relatively longer serviee life of the cables.
