How much does a meter of dual-core single-mode optical fiber cost

The price of a single-mode dual-core (duplex) optical fiber typically ranges from $0.30 to $2.80 per meter, depending on cable type, brand, and protection features.Price Range and FactorsStandard indoor single-mode duplex cable: Around $0.30 to $1.50 per meter, suitable for office or data center runs with simple routing and LSZH or PVC jackets .Outdoor or armored single-mode duplex cable: Can cost $1.20 to $3.00 per meter, with armored or gel-filled variants for harsh environments or direct burial .Premium brand fiber (e.g., Corning): May push the price toward the higher end of the range due to lower attenuation and higher quality glass .Key Price DriversFiber Count: Dual-core (2-core) cables are cheaper than higher-count cables like 12-core or 24-core .Cable Construction: Loose-tube, tight-buffered, armored, or gel-filled designs affect material and production costs .Jacket Material: LSZH jackets are common for indoor safety, while PE or UV-resistant jackets are used outdoors, increasing cost .Installation Environment: Outdoor, aerial, or direct-burial installations require more robust protection, raising the per-meter price .Pre-Termination: Factory-terminated cables cost more upfront but reduce on-site splicing labor, which can save overall project costs .Practical ConsiderationsFor short indoor runs, expect to pay closer to $0.30–$1.50 per meter.For long outdoor or armored installations, budget $1.50–$3.00 per meter.Bulk orders or direct manufacturer purchases can reduce costs by 20–30% compared to retail . In summary, a single-mode dual-core optical fiber is generally affordable for standard applications, but the final cost depends on cable protection, brand, and installation requirements.
