Shanghai Unicom Tower – China
Molex has designed a Category 6, Optical Fiber Cabling Solution and flexible PDS solution comprised of five subsystems for Unicom Tower, the headquarters office of China Unicom Shanghai Branch.
Materials of China Unicom Optical Cables
China Unicom optical cables are primarily made of doped silica glass fibers with polymer coatings, mechanical stress-resistant structures, and water-resistant materials.Core Optical FiberThe main data-transmitting component of China Unicom optical cables is the single-mode optical fiber, specifically the G.654E standard used in high-speed backbone networks . The fiber core and cladding are made of ultra-pure silica (SiO₂), often doped with germanium to control the refractive index and optimize signal transmission . These fibers are designed for low attenuation and large effective area, which improves performance in 400G and higher-speed networks .Protective Coatings and BuffersTo protect the delicate glass fiber, China Unicom cables use dual-layer UV-cured acrylate coatings: a soft primary coating and a hard secondary coating . These coatings provide mechanical protection, reduce microbending losses, and enhance durability during installation and operation. Additionally, polymer mechanical buffer coatings and PBT bushings are applied to further protect the fiber from stress and environmental factors .Cable Structure and Environmental ProtectionThe optical cables include mechanical stress-resistant structures, such as aramid yarns or FRP rods, to maintain integrity under tension and bending . Water-resistant special fiber pastes and cable pastes are incorporated to prevent moisture ingress, which is critical for outdoor and harsh-environment deployments, such as in Xinjiang and Shandong . Some cables may also include metallic components for grounding or additional protection, depending on the application .SummaryIn essence, China Unicom optical cables combine:Doped silica glass fibers (core and cladding)UV-cured dual-layer polymer coatingsMechanical buffers and stress-resistant structuresWater-resistant pastes and protective jackets These materials ensure high-speed, low-loss transmission, durability in extreme climates, and suitability for large-scale backbone network deployment .
