Abstract
A filament (36) of a material having resilient springlike characteristics is helically wound to form a hollow tubular guide (34) for an optical fiber (14) dispensed from a wound stack (37). The guide can have a constant diameter (34) or, alternatively, include portions of a different diameter (44, 50, 52). A further embodiment especially advantageous for use in a helicopter (10) positions a rigid tube (58) around the guide (56) leaving a portion of the guide extending from the rigid tube.
