Rebuilding a High-Stakes Fiber Network

JDH restored critical long-haul fiber performance for a national utility provider by engineering and supporting the replacement of approximately 22,000 feet of direct-buried cable that was causing excessive dB loss. Through detailed field verification, route optimization, and proactive coordination with permitting agencies, the project improved network reliability while minimizing future maintenance risks. The successful outcome showcased JDH’s turnkey capabilities to plan, design, coordinate, and support construction of complex, high-stakes fiber engineering projects, further strengthening our long-standing partnership and positioning us for continued collaboration.

The project took place in Lebanon, Indiana, and involved replacing a long-haul direct-buried fiber segment experiencing significant signal loss due to multiple splice points and aging infrastructure. The route presented substantial challenges including congested and narrow right-of-way, unlocatable facilities, interstate and creek crossings, buried manholes, and simultaneous utility construction in the same corridor. JDH worked closely with the County Highway Department and INDOT to navigate complex permitting requirements while providing the client with multiple design options for informed decision-making. Detailed as-built documentation and identification of retired facilities delivered long-term value by improving record accuracy and eliminating unnecessary ongoing costs for inactive infrastructure.
