Abstract
An optical fiber ribbon splitting tool that accommodates an optical fiber ribbon in guide groove portion and splits longitudinally the accommodated optical fiber ribbon, where a cross section of the guide groove portion comprises a bottom portion with a width slightly smaller than a width of an optical fiber ribbon to be split, and side wall portions each composed of a straight-slant surface tilting so that a groove width becomes narrower as closer to the bottom portion from an opening portion in the guide groove portion.
Claims15
An optical fiber ribbon splitting tool that accommodates an optical fiber ribbon in a guide groove portion and splits longitudinally an accommodated optical fiber ribbon, wherein a cross section of said guide groove portion comprises a bottom portion with a width slightly smaller than a width of the optical fiber ribbon to be split, and side wall portions each composed of a straight-slant surface tilting in such a manner that a groove width becomes narrower as closer to said bottom portion from an opening portion in said guide groove portion.
An optical fiber ribbon splitting tool that splits longitudinally an optical fiber ribbon, said tool comprising:
- a guide member which is separable from said splitting tool and has a guide groove portion that accommodates the optical fiber ribbon and an attachment engaging portion;
- and
- a guide attachment portion which is provided in said splitting tool, engages in said attachment engaging portion of said guide member and thereby fixes said guide member to said splitting tool in an exchangeable manner.
An optical fiber ribbon splitting tool that sandwiches an optical fiber ribbon vertically and splits the optical fiber ribbon by shear stress along a longitudinal direction, said tool comprising:
- guide groove portion that accommodate the optical fiber ribbon to be split;
- and
- a shear splitting portion comprising a pair of fixed members which are vertically provided in a cut portion formed so as to separate said guide groove portion into two portions and sandwich vertically therebetween a part of the optical fiber ribbon in a width direction at a position lower than a bottom portion of said guide groove portion and hold said conductor at said position, and a pair of movable members which are vertically provided adjacent to said fixed members in said cut portion, sandwich vertically therebetween a remaining part of the optical fiber ribbon in a width direction at the same position as said fixed members to be held, and when pressed by force more than a predetermined level, move upwardly while holding said part of the optical fiber ribbon in the width direction.
A method of splitting longitudinally part of an optical fiber ribbon, comprising the steps of:
- (a) sandwiching the optical fiber ribbon and thereby applying a stress in one direction so as to provide a portion of the optical fiber ribbon to be split by shearing with a sag portion in said one direction;
- and
- (b) applying a shear stress in a direction opposed to said one direction to the portion of the optical fiber ribbon with the sag portion provided, and splitting a part of the optical fiber ribbon in a width direction by shearing.
