Electronic Products and Expert Reviews
MRO delivers quality cables, wiring harnesses, rack builds, electronic enclosures, control panels, control systems and more. We also deliver the answers to very complex and sometimes daunting questions that could change the course of history, or at the very least, impact science and peoples lives. One exciting project that MRO provided expertise and product for was a cutting-edge telescope.
In British Columbia Canada, there is a facility known for science and technology research called the Dominion Radio Astrophysical Observatory, or “DRAO”. The facility is internationally known and is home to astronomers, astrophysicists, engineers and technologists, all working towards the design and development of world-class instrumentation. One of these leading-edge projects is the CHIME telescope.
When the CHIME radio telescope was under construction, they required specialized cable assemblies with high signal velocity capabilities. The project was extraordinarily complex, consisting of fixed linear reflectors with a bridgework of many antennas at the focal plane of the reflector. There are several reflectors. The signals from each antenna are connected to a coaxial cable. These signals are cabled into a combiner. The important thing is they have to be very precise in phase. It is not much different from an optical lens where all the rays of light have to focus at the same point or the image will be fuzzy. The time the signal travels from one end of the cable to the other has to be the same for each cable, give or take 1 nanosecond. A rough definition of a nanosecond is the time it takes light to travel one foot in a vacuum.
Even with the same type of cable from the same lot, the transit time will vary, so a method had to be found to measure that time. A couple of methods were tried, and the optimum one was a network analyzer. We used an Anritsu S331E. The astronomy staff at the UBC wrote a script that allowed the cable serial number barcoded and linked to the cable loss and the electrical length of each unique cable.
Our Schleuniger automated cable cutting and reeling machine was set up to cut over 2000pcs of these 50-meter cables very consistently, however, getting all our cable for that job from the same lot, a number of cables were out of tolerance and had to be re-terminated if they were too long, even though the physical length was within the specification. The short ones were repurposed.
General Dynamics Systems Canada is a global aerospace and defense company. Manufacturing products from Gulfstream business jets and combat vehicles to nuclear-powered submarines and communications systems, people around the world depend on their products and services for their safety and security. MRO is thrilled to have worked with General Dynamics, who had this to say about our work:
“MRO has a proven track record of consistently exceeding 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. On time and with a high level of quality.”
Vertically Integrated Manufacturing Dynamic for a broad range of industries
