Optical fibers enable fast, noise-free signal transmission over long distances, but maintaining that performance in demanding environments requires a reliable sealing solution. Douglas Electrical Components’ OptiSeal™ fiber optic feedthroughs are designed to deliver true hermetic sealing, with pre-wired and pre-tested assemblies that ensure consistent performance and easy integration.

Our team hermetically seals directly to the optical fiber, supporting both vacuum and positive pressure applications. With the ability to create hybrid harnesses that combine fiber optics with copper wires, thermocouples, and power cables, OptiSeal helps reduce weight and cost while improving overall system reliability.

From hermetically sealed MIL-spec connectors to plug-and-play OEM solutions, OptiSeal feedthroughs are built for flexibility and durability. Whether for industrial, IoT, or military applications, Douglas Electrical Components provides custom-engineered solutions to protect high-speed communication systems in even the most demanding conditions.
