Douglas Electrical Components - Model OptiSeal Series -Hermetic Optical Fiber Feedthroughs
Optical fibers are an efficient way to transmit fast, noise-free signals over long distances. If you’re looking for reliable fiber optic feedthroughs, Douglas Electrical Components has got you covered with our OptiSeal™ products. Our pre-wired and pre-tested interconnecting harnesses and feedthroughs can be configured to accommodate any combination of optical fibers you need. Our team carefully hermetically seals directly to the optical fiber to ensure a true hermetic seal within the bulkhead of the assembly to operate in vacuum and/or positive pressure applications. In-house testing further confirms optical continuity of the optical fibers.
Our certified IPC-620 technicians can handle optical fibers carefully to effectively seal the feedthrough assembly. Designs are available for both vacuum and positive pressure applications. With OptiSeal, you can create a hybrid feedthrough harness that can combines a mixture of copper wires, fiber optic cables, thermocouples, power cables, shielded pairs, triplets, and quads; this can reduce cost and weight, while increasing reliability within your equipment or assembly. Mating harnesses with breakouts can be custom designed with optional features such as FC/APC terminations within individual armored fiber channels.
Douglas Electrical Components can hermetically seal MIL-spec and industrial fiber optic connectors through our backpotting process, making it possible to create a plug-and-play solution in an OEM application requiring optical fibers, from IoT control boxes to military equipment. OFC connector assemblies can also be hermetically sealed for simple integration and ultimate protection of the fiber. Integrate various fiber optic terminated patch cables directly into optical fibers to both protect the fiber and develop a solution that is designed ready for installation.
We also offer design support for explosion-proof assemblies exposed to hazardous liquids and gases with standard taper threads, O-ring seals, and flange designs. OptiSeal can be configured for wire-to-wire, cable-to-wire, as well as connector-to-wire assemblies in UHV and pressurized environments.
Our products also support applications requiring high-speed, complex communication over long distances. Contact the factory for customized bulkhead connector feedthrough designs and capabilities for fiber optic connections.
