Method and spacer for assembling flexible optical waveguide ribbons, and assembled stack of such ribbons
A method and spacer for assembling flexible optical waveguide ribbons and assembled stack of such ribbons. The method includes the steps of: providing at least two optical waveguide ribbons and a spacer, which includes at least two calibrated spaces; positioning a ribbon stack in the spacer, where the ribbon stack includes the at least two optical waveguide ribbons stacked on top of each other; constraining positioned ribbon stack in one of the calibrated spaces; and fixing constrained ribbon stack in the calibrated spaces.
1. A method for assembling flexible optical waveguide ribbons comprising:
positioning an optical waveguide ribbon in a receptacle;
applying an adhesive into said receptacle until an upper surface of said adhesive is located above an upper surface of said optical waveguide, said adhesive filling spaces between said receptacle and said optical waveguide ribbon;
engaging a portion of a spacer element in said receptacle until a calibrated space is achieved between said portion of said spacer element and said receptacle, wherein said optical waveguide ribbon is constrained and fixed in said calibrated space;
removing said spacer element; and
repeating said positioning, said applying, said engaging and said removing to obtain a N+1th optical waveguide ribbon fixed in said receptacle with respect to a Nth optical waveguide ribbon, wherein N is an integer greater than 0.
2. The method of claim 1 , wherein a layer of said adhesive is present between said N+1th optical waveguide ribbon and said Nth optical waveguide ribbon.
3. The method of claim 1 , wherein a height of said calibrated space is greater than a thickness of said optical waveguide ribbon.
4. The method of claim 1 , where said spacer element is dimensioned and shaped such that said portion of said spacer element can be engaged in the receptacle.
5. The method of claim 4 , wherein said spacer element is a T-shaped stamp, wherein a vertical portion of said T-shaped stamp comprises said portion of said spacer element.
6. The method of claim 5 , wherein said receptacle is U-shaped, wherein during said engaging, said vertical portion of said T-shaped stamp is engaged in said U-shaped receptacle.
7. The method of claim 1 , wherein said optical waveguide ribbon is constrained and fixed in said calibrated space by curing said adhesive.
8. The method of claim 1 , wherein a surface of said portion of said spacer element in contact with said adhesive is coated with an anti-sticking coating.
9. The method of claim 1 , wherein a non-engaged portion of said spacer element further comprises a plurality of stands having different dimensions.
