What Do You Know About Special Optical Cables? Only They Can Be Used in These Special Scenarios
In special environments or functional requirements that conventional optical cables cannot cope with, special optical cables have become the core of solutions with their unique designs. From high-voltage power communication to underwater laying, from extreme temperature environments to optical fiber sensing monitoring, special optical cables are supporting more and more high-end application scenarios. Understanding their classification and scope of application is crucial for industry practitioners. The power communication field is one of the core application scenarios of special optical cables. OPGW (Optical Fiber Composite Overhead Ground Wire) has both lightning protection and communication functions, suitable for high-voltage transmission lines above 66kV; ADSS (All-Dielectric Self-Supporting) optical cables support live-line erection, suitable for old network transformation or long-span scenarios. In extreme environments, rodent-proof optical cables adopt stainless steel tape armoring, which can resist gnawing damage in farmland and forests; underwater optical cables adapt to riverbed environments with unstable riverbeds and high flow rates through double-layer steel wire armoring design. Under complex erection conditions, micro air-blown optical cables can be laid in micro-pipes by air blowing, solving the problem of tight pipeline resources; optical fiber sensing cables can realize real-time monitoring of temperature, pressure and other parameters, and are applied in intelligent manufacturing, oil pipeline monitoring and other fields. The key to selecting special optical cables is "precise matching with scenario requirements". Only by selecting the corresponding structural design according to environmental characteristics and functional requirements can the communication be stable and reliable.
