OpTech Harness Lab

The OpTech Harness Lab (OHL) delivers high-reliability harness and cable solutions for satellites, payloads, FlatSats, and test systems. Housed in a dedicated ISO Class 8 (100k) cleanroom in our AS9100-certified Sterling, VA facility, the OHL is staffed by a seasoned team of engineers, technicians, and quality assurance professionals with decades of spaceflight experience.

COre Capabilities

  • End-to-End Harness Development

    From requirements through flight-ready hardware — including design, procurement, fabrication, and testing.

  • Custom Harnessing

    Micro-D through D38999 connectors, MIL-STD-1553 harnessing, Winchesters, and complex builds including embedded resistors, diodes, and thermal components.

  • 3D-Printed Integration

    Custom mounts and structures to optimize cable routing and support unconventional mechanical layouts.

  • Ground & Thermal Harnessing

    Support for thermostats, thermistors, heaters, thermocouple welding, grounding handshakes, and lug terminations.

  • Lab & Test Support Builds

    Adapter harnesses, bypass harnesses, and backshell-less solutions tailored to test rack integration and diagnostics.

Certifications & Standards

  • AS9100 Certified

  • TS Facility Clearance

  • J-STD-001 — Soldered Electrical and Electronic Assemblies

  • NASA-STD 8739.4 — Crimping, Cable Harnessing, and Wiring

  • IPC/WHMA-A-620 — Cable and Wire Harness Assemblies Acceptance

On-Site Testing Services

  • Pull testing

  • Continuity & isolation testing

  • Hi-pot (high potential) testing

All tests are performed in-house to validate build integrity and mission readiness.

Design Tools & Collaboration

We design using advanced platforms including Creo for 3D mechanical modeling and Zuken for electrical harness design and documentation. These tools enable accurate, build-ready outputs and integration with other spacecraft subsystems. Our in-house capabilities are supported by a trusted network of suppliers and industry partners, ensuring agility and scalability for fast-paced missions.

Location & Integration

OHL is located within our Sterling, VA campus — just 3.5 miles from Dulles International Airport — and directly integrated with our spacecraft assembly and integration workflows. This proximity enhances cross-functional collaboration and schedule responsiveness.
