An exemplary optical cable includes a first type of ribbon bundles, a second type of ribbon bundles, a third type of ribbon bundles, a plurality of strength rods, and an outer jacket. Each of the first, the second, and third type of ribbon bundles includes a first, a second, a third flexible ribbon with corresponding optical fibers disposed within a ribbon bundle jacket. The first type of ribbon bundles is arranged in an interlocking pattern in a central region of the optical cable. The second type of ribbon bundles and the third type of ribbon bundles are disposed around the first type of ribbon bundles in a peripheral region of the optical cable. The outer jacket is disposed around the second and the third type of ribbon bundles, and the plurality of strength rods being at least partially embedded in the outer jacket, where the cumulative cross-sectional area of all of the strength rods in the cable divided by the cumulative cross-sectional area of all glass parts of the optical fibers in the cable is a first value less than 0.22, and where, at a temperature between −40° C. and 0° C. and at a wavelength of 1550 nm, the attenuation increase of the optical fibers in the cable relative to 25° C. is below 0.15 dB/km.

High fiber density cable with flexible optical fiber ribbons

An optical-fiber ribbon having excellent flexibility, strength, and robustness facilitates separation of an optical fiber from the optical-fiber ribbon without damaging the optical fiber's glass core, glass cladding, primary coating, secondary coating, and ink layer, if present.

Flexible optical-fiber ribbon

The present disclosure relates to an impact resistant, multipolar power cable () comprising, a plurality of cores (), each core () comprising at least one conductive element () and an electrical insulating layer () in a position radially external to the at least one conductive element (). The cores () are stranded together so as to form an assembled element providing a plurality of interstitial zones (). An expanded polymeric filler () fills the interstitial zones () between the plurality of cores (). An expanded impact resistant layer () is in a position radially external to the expanded polymeric filler () and comprises a polymer that differs from the expanded polymeric filler ().
