Abstract
An improved optical signal transmission media comprises at least one light-transmitting fiber core defined by a cladded optical fiber, and a buffering surrounding the light transmitting fiber core. The buffering is defined by a closed-cell porous polymer material.
Claims2
An improved optical signal transmission media comprising:
- at least one light-transmitting fiber core including a cladded optical fiber;
- a buffering surrounding the light transmitting fiber core, the buffering defined by a closed-cell porous polymer material;
- and
- wherein said buffering is comprised at least in part from a group consisting of foamed polyethylene, porous polypropylene, foamed polyurethane, foamed polytetrafluoroethylene, foamed flourinated ethylenepropylene (FEP), foamed rubber, and biaxially oriented, closed cell, 50% porous co-extruded polypropylene film.

An optical fiber ribbon cable comprising:
- a plurality of polymer coated optical fibers disposed in parallel arrangement, one to each other;
- a buffering at least partially surrounding said plurality of optical fibers, the buffering defined by a closed-cell porous polymer material;
- and
- wherein said buffering is comprised at least in part from a group consisting of foamed polyethylene, porous polypropylene, foamed polyurethane, foamed polytetrafluoroethylene, foamed fluorinated ethylenepropylene (FEP), foamed rubber, and biaxially oriented, closed cell, 50% porous co-extruded polypropylene film.
