Amphenol introduces the HMAtwo Series into the Harsh Environment product portfolio. This legacy
hermaphroditic fibre optic lens connector facilitates the inter-connection of multiple identical fibre optic
cable assemblies known as daisy chaining, thus eliminating the need for polarising the assemblies and
the use of in-line adapters. Lens technology is less vulnerable to mud, dirt and other contaminants than
the traditional physical contact technology. This allows rapid and reliable deployment of assemblies in
extreme environments. The Connector is available in 1 to 4 way configurations for multi-mode fibres at
both 850 and 1300nm applications and is inter-mateable/interchangeable with other manufacturers
equivalent products.
The standard connector components are aluminium with a long life Hard Black anodise finish with the
coupling ring featuring a protective “rubber” overmould. The connector has been designed for both
factory and field termination directly onto standard tactical fibre optic cable without specialist lens
termination tooling. The connector construction allows for both first line field repairs and return to base
overhauls of both the connector and the Lens assembly.
