IOL specializes in large and complex construction custom bulk cable.

Our capabilities include:
  • Massive scaling of production when required... and nimble enough to compete at lower volumes;
  • Significant investments in test gear, fixtures & software;
  • Cabling equipment to perform a full range of planetary production;
  • A variety of low capacitance, controlled impedance solid & foamed insulations;
  • Numerous shield types deployed for a wide range of shield effectiveness & applications;
  • Durable, flexible jacketing compounds to meet virtually all environmental and usage requirements;
  • Decades of experience and expertise in custom bulk cable design and manufacturing.

We have built cables comprised of many multiple individual coaxial cables; designs featuring nineteen 12AWG conductors around a DMX core; an uber-flexible cable of 48 individually shielded & jacketed OFC twisted pairs; and, massive custom cables exceeding 50mm (2") in diameter.
