This decade has seen a series of game changing innovations, such as the Procyon Blade, the MHC® T2 & MHC® T3 Cable Assemblies, and most recently, the patented Category 8 Jacks and Plugs which feature a new, easy-to-terminate construction. In Prysmian, we design our special fibre optic cables to overcome the obstacles presented in the creation of communication networks. We provide new solutions specifically for industrial, Oil & Gas, underwater and flooded areas and harsh environments. The application of OPGW cable plays a dual function of ground and communication, effectively improving the utilization rate of power towers. Winding fiber optic. OFS specialty optical fibers are application-specific and unique-purpose products used in diverse applications that may require among other things-- environmental resistance, wide operating temperature ranges, optimal bend performance, non-traditional fiber sizes, and non-traditional operating. Special fiber optic projects are created where standard solutions reach their limits and special requirements demand individual approaches. Our development process for tailor-made fiber optic projects is based on 30 years of practical experience and the principle of intelligently expanding proven. Types of power special optical cable and field optical fiber Power special optical cable generally refers to OPGW (optical composite ground wire), OPPC (optical composite phase wire), MASS (metal self-supporting optical cable), ADSS (all-dielectric self-supporting optical cable), ADL (phase/ground.
