DEFINITION

Classification: 385/100

OPTICAL TRANSMISSION CABLE:

(under the class definition) Subject matter wherein an optical fiber or fibers are incorporated into an assembly that provides tensile strength and external protection for

the fibers.

(1) Note. If significant electrical structure is claimed, classification is in Class 174.

(2) Note. This subclass includes optical fiber cables having additional transmission means such as electrical conductors within the cable where the optical fibers transmit light.

(3) Note. Sometimes the optical fibers within the cable are helically or reverse helical (S-Z) wound in order to provide protection thereto.

(4) Note. A single optical conductor with a protective coating not providing tensile strength is classified in subclass 128. A single conductor with cladding not used for protection is classified in subclasses 123+.

SEE OR SEARCH THIS CLASS, SUBCLASS:

115+, for an optical fiber bundle which is not in an assembly providing tensile strength and external protection thereto. 123+, for an optical fiber waveguide with cladding, per se.
