Single fiber assemblies are employed whenever light must be transmitted over a certain distance along a convoluted path. FTO manufactures several grades of single fiber assemblies and cables. We specialize in making extremely rugged cables for harsh environments. Our assemblies can be customized based on your needs and specifications.
