ABSTRACT:
An optical fiber unit for forming high-density optical cables in optical communication networks includes a core body having a twisted tensile strength member extended along the central axis thereof, spiral grooves in the outer surface thereof, and tape-shaped optical fibers placed in the spiral grooves of the core body, with the twist direction of the twisted member and the spiral direction of the grooves being opposite one another. Thus, when the core body is under tension, the angular moment produced in the tensile strength member and that produced in the ribs formed between the spiral grooves are opposite in direction and equal in magnitude, whereby the angular moment of the entire core body is substantially zero. As a result, the optical fiber residual strain produced during manufacture can be controlled with high precision.
