Cost of ADSS for Long-Distance Optical Cables in Rail Transit
To budget accurately for ADSS optical cables, you must go beyond the base per-kilometer price. Every year, our sales team fields hundreds of RFQs from contractors and distributors who later discover their ADSS cable budgets were off by 30% or more. ADSS optical cables 1 The gap between a quoted price and the real landed cost has caused delayed projects, blown budgets, and strained. ADSS cable cost may be determined by the following factors, among others: Number of Fibers (Core Count) – More fibers = higher cost. Sheath Type – Consequently, the price of an anti-tracking sheath (typically referred to as AT) is higher than that of a standard PE one. The loose sleeving (and filler rope) is twisted around a non-metallic central reinforcement core (FRP) to form a. ADSS optical cable (All-Dielectric Self-Supporting Optical Cable) is widely used in power systems, high-voltage transmission lines, and other fields due to its metal-free and self-supporting characteristics.
