Underground Optical Fiber Cable (OFC) installation in densely populated urban centers presents unique engineering challenges, from negotiating right-of-way (RoW) approvals to protecting underground utility lines.
HDD (Horizontal Directional Drilling) Techniques
Trenchless HDD technology allows fiber ducts to be laid under major highway intersections, railway tracks, and concrete paved roads without digging open trenches. This reduces traffic congestion and project turnaround times drastically.
Precision Fusion Splicing
Optical fiber joints require sub-micron alignment accuracy. Using automatic core-alignment fusion splicers, our field crews keep splice loss under 0.02 dB per joint, ensuring peak optical transmission efficiency.
