BIRNS has a nearly 70 year history of innovating and ad- vancing technology for the subsea industry. When the com- pany was created in 1954, it started out supplying lighting sys- tems and other key marine equipment for the US Navy, and over the subsequent decades continued that naval partnership, and expanded with support of high pro? le projects for custom- ers spanning the globe. Today it continues breaking many of the technological barriers formerly found in designing high 3GHz. An exciting development to access this innovative con- performance connectors, cable assemblies, penetrators and nectivity technology was launched in 2022, with the compa- lighting systems, and as a result, BIRNS products are trusted ny’s new interactive ecommerce site.
