Indoor/Outdoor Riser Ribbon Cable


Sumitomo Electric Lightwave’s 4th Level® Indoor-Outdoor Riser Rated Ribbon fiber optic cables feature 250μm color-coded optical fibers for easy fiber identification and Sumitomo’s exclusive patented easy split and peel technology for easy fiber access and unprecedented ease of handling and splicing. The twelve fiber ribbons enable connectorization with both MPO and all industry standard connectors. The non-preferential bend axis allows for easy installation in space-constrained areas.

The cables include a dielectric strength member with a flexible, flame-retardant outer jacket in its all dielectric cable construction that eliminates grounding or bonding.
