Optimum Systems International is a high technology manufacturer specialized in quality custom and special application cable assemblies, wire harnesses, panel assemblies, and electro-mechanical assemblies. We can provide fully assembled and tested product for requirements ranging from prototype to volume production, and at a competitive price.

Located in Arvada, CO, we grew from a demand in the market for a company that could understand and fabricate harnesses to support the high-tech requirements of the Hot-Pluggable power supply industry. As we grew in this segment, we were also exposed to other very specialized applications ranging from PLC panel assemblies to ground support cables for missile systems.
