InfiniBeam Expanded Beam Cable Assemblies


Stran Technologies InfiniBeam® expanded beam fiber optic assemblies provide the ultimate in reliable performance in harsh environments where water, mud, dust and fluid exposure are a concern. Utilizing expanded beam technology, the design and packaging of these connectors provide a robust connectivity solution resistant to corrosion, mechanical and thermal shock while inherently providing easy field cleaning. Available in a variety of configurations, number of channels and sizes.

Expanded beam inserts expand optical signals by 200x reducing the effect of dust, dirt and other contaminants on the optical data communications path. The inserts offer easy field cleaning without tools on the hermaphroditic interface.
