Abstract
An optical fiber ribbon stack in which individual ribbons are pre-stressed according to a predetermined tension/compression distribution before being laminated together in a stack. This distribution corresponds to expected thermo-mechanical conditions which occur during the service of the cable housing the ribbon stack, and may be linear or non-linear, symmetric or non-symmetric, producing straight or curved stacks.
Claims20
An optical fiber ribbon stack, comprising:
- a plurality of optical fiber ribbons laminated together to form a stack;
- wherein some of the optical fiber ribbons include an internal force of a tensile pre-stress and some of the optical fiber ribbons include an internal force of a compression pre-stress.
An optical fiber ribbon stack, comprising:
- a plurality of optical fiber ribbons laminated together to form a stack;
- wherein some of the optical fiber ribbons include an internal force of one of a tensile pre-stress and a compression pre-stress, and wherein a stress distribution of the stack is symmetric.
A method for forming a pre-stressed ribbon stack for use in a cable, comprising the steps of:
- imparting different tensile stresses on respective ones of the plurality of ribbons;
- and
- laminating the pre-stressed ribbons to form a laminated ribbon stack;
- wherein after lamination, some of the ribbons include an internal force of a tensile pre-stress and some of the ribbons include an internal force of a compression pre-stress.
A method for forming a pre-stressed ribbon stack for use in a cable, comprising the steps of:
- imparting different tensile stresses on respective ones of the plurality of ribbons;
- and
- laminating the pre-stressed ribbons to form a laminated ribbon stack, wherein the stress distribution of the laminated ribbon stack is symmetric.
