What our clients have to say.

MRO has consistently met our strict specifications, challenging requirements and aggressive lead times. Our Military Spec Cable Assemblies require superior manufacturing techniques, not common in conventional cable assembly manufacturing. MRO has the required experience and capabilities for our Military Specifications and complex designs.

Effective communication is MRO’s strongest point. Particularly, openness to listen.

Recently, we introduced MRO to some of our end customers. The key takeaway was that they were impressed with MRO’s understanding and execution of the customers’ complex designs.

MRO has become an integral part of our success by effectively delivering tight schedule requirements, from large orders to small design verification's. On time and with a high level of quality.

Are your cable assemblies over-engineered?

An over-engineered cable assembly can increase lead times and drive up costs. Working with your manufacturer to look for design opportunities and component substitutions can help mitigate these issues.

Case Studies

Detecting gravity waves - the CHIME telescope project

The CHIME radio telescope was under construction at the Dominion Radio Astrophysical Observatory in British Columbia, Canada and and required specialized cable assemblies with high signal velocity capabilities.

Developing a rugged cable assembly for seismic data

A client had two challenges for us to solve. The first was a torque problem due to the wear and tear from movement during use of the cable assembly. The second was from local camels that had wandered into the area and were chewing through the cable assemblies.
