Single-mode fibres confine optical propagation to the fundamental LP₀₁ mode only — light travels essentially parallel to the fibre axis with minimal modal dispersion. Core: 9 μm diameter; cladding: 125 μm; cutoff wavelength: ~1,260 nm (ensuring only fundamental mode at 1,310/1,550 nm telecom bands). Advantage in reeling service: Modal dispersion (temporal spreading from different modes arriving at different velocities) is completely eliminated, enabling high-speed data (10–100 Gbps) over extended distances without signal degradation. For mission-critical automated port cranes transmitting high-definition video from STS gantry cameras, SMF is essential. Challenge: SMF is mechanically fragile — the 9 μm core is minuscule; any microbend creates mode coupling (fundamental mode energy leaks to radiated/cladding modes), causing signal loss. RHEYCORD®-OFE loose-tube jelly-fill is engineered to minimize mechanical stress on SMF.
