Ultimately, for a new interface to be adopted, the user experience must be positive. One of the key aspects that impact the experience of the user is mating style. The most prominent feature of the HD-BNC™ is the bayonet style mating. Users of the BNC, especially field installers are very familiar and comfortable with this mating style. Incorporating this mating style in a high density variant was a mandatory requirement during the development. A secondary advantage of the bayonet is the ability to validate the mated condition visually. The HD-BNC™ features two full axial grooves on the outer surface which are oriented to bayonet lug engagement features as shown. This allows a user to inspect the mating condition of many connectors with a clear visual indication.
