An optical fiber ribbon includes an interfacial layer between a plurality of coated optical fibers and a common coating layer. The interfacial layer includes a liquid lubricant material dispersed in a cross-linked solid material. The optical fiber ribbon is both peelable and thermally strippable. The interfacial layer adheres more strongly to the common coating material than to the coated optical fibers. The interfacial layer may be provided either as the outer layer of each of the individual coated optical fibers or as an inner layer of the common matrix coating.

Why it's free to use
- Filed March 4, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 4, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 4, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
