SUSPENDED OPTICAL COMMUNICATION CABLE Russian patent published in 1997 - IPC

FIELD: electrical engineering, design of fibre-optical communication lines on electric power lines. SUBSTANCE: optical cable has central dielectric element, optical fibres in polymer modules with hydrophobic filling agent, internal dielectric sheath, dielectric sheath compensating for twisting of cable and external dielectric sheath. Outer surface of external dielectric sheath has sinusoidal form along axis of cable with period of sinusoid T ≥ ndc, where T is period of sinusoid; DC is diameter of cable; n is positive integral number, n should be small number determined by rate of technological process of application of external dielectric sheath on core of cable. EFFECT: enhanced communication stability and reliability. 2 dwg
