Price of fiber optic cables for smart buildings in Sri Lanka s vertical shafts

Fiber optic cables for smart building vertical shafts in Sri Lanka typically range from LKR 1,500 to LKR 15,000 per meter, depending on type, core count, and armoring.Price OverviewFiber optic cable prices in Sri Lanka vary widely based on cable type, core count, indoor/outdoor rating, and armoring. For smart building vertical shafts, indoor-rated tight-buffered multimode cables or armored singlemode cables are commonly used to ensure durability and minimal signal loss in vertical risers . Typical price ranges include:Indoor Multimode (OM3/OM4, 4–12 cores, LSZH jacket): LKR 1,500–3,500 per meter Indoor Armored Singlemode (G652.D, 6–12 cores): LKR 3,500–6,500 per meter High-Density Backbone Cables (24–48 cores, armored, singlemode): LKR 7,000–15,000 per meter Prices are influenced by import costs, as over 80% of fiber optic cables in Sri Lanka are imported from China and Hong Kong, and by technological features such as bend-insensitive fibers (G657.A1/A2) which reduce installation costs and breakage .Factors Affecting CostCable Type: Singlemode cables are generally more expensive than multimode due to longer transmission distances and lower attenuation.Armoring: Armored cables for vertical shafts or risers provide mechanical protection but increase cost.Core Count: Higher core counts (24, 48, 96 cores) are used for backbone infrastructure and are priced higher.Supplier and Brand: International brands like A&G (France) and Dintek (Taiwan) may carry a premium for quality and reliability .Logistics and Currency Fluctuations: Import duties, freight, and USD/LKR exchange rates can affect final landed cost .Recommendations for Smart Building Vertical ShaftsUse LSZH (Low Smoke Zero Halogen) indoor-rated cables for fire safety compliance.Consider armored singlemode cables for vertical shafts to prevent damage during installation.Match core count to building network requirements; 6–12 cores are typical for small to medium buildings, while 24–48 cores suit larger smart buildings or backbone connections.Plan for lead times of 4–8 weeks due to import logistics . By selecting the appropriate cable type and supplier, smart building projects in Sri Lanka can balance performance, safety, and cost efficiency.
