DEFINITION

Classification: 264/1.28

Forming fiber bundle or cable (e.g., covering, sheath, etc.):

(under subclass 1.24) Processes wherein at least two optical fibers or waveguides are incorporated into an assembly (a) that provides tensile strength and external protection or (b) are adjacent one another to guide light collectively.

(1) Note. Extrusion processes involving forming a cable or fiber bundle are properly classified here. Extrusion processes involving a single (individual) optical fiber or waveguide are classified below.

(2) Note. Processes of forming or treating cables or fiber bundles wherein optical fibers or waveguides are (a) embedded in a matrix, (b) placed in separate preformed grooves or cavities, (c) sheathed, or (d) fastened adjacent one to another are proper for this subclass.
