A flexible clad, monofilament optical conduit having a flexible light transmitting polymeric core having a relatively high refractive index which is surrounded by a shrunk, heat shrinkable cladding having a relatively low refractive index in comparison to that of the core and which has a relatively small, uniform gap between the outer periphery of the core and the inner periphery of the heat shrinkable cladding, and a method of manufacture whereby a plurality of such conduits are simultaneously produced by polymerization of the conduit core forming material within a length of unshrunken heat shrinkable material which in turn is contained within a relatively thick, durable protective tubing and removal of the relatively thick protective tubing subsequent to polymerization and then shrinking the heat shrinkable material to form a relatively uniform gap between the core and the clad.
