ABSTRACT:
Provided is an optical cable using multifiber optical units. Each of said multifiber optical units has a laminated body of a tape-type optical unit accommodated in a groove formed in a rod-like member. The tape-type optical unit is constituted by a plurality of optical fibers arranged in one row and coated collectively. The improvement is that the distance between the center of the rod-like member and a bottom portion of said groove is made to be equal to or larger than one half of the height of the laminated body to thereby reduce side pressure exerted on the tape type-optical units at the groove bottom portion thereof.
