Freeform Ribbon® Flexible Indoor Plenum Cordage

Sumitomo Electric Lightwave’s Freeform Ribbon® Flexible Indoor Plenum Cordage is designed for maximum fiber density with savings of valuable space in cable trays and patch panels, making them an ideal choice for interconnect applications. The cord features 250 μm color-code optical fibers for easy fiber identification for easy fiber access and unprecedented ease of handling and splicing. The twelve fiber ribbon groupings enable easy connectorization with both MPO and all industry standard connectors. Sumitomo Electric’s patented Freeform Ribbon® construction is designed to both pack densely in small form factor cables while still being capable to transform quickly, by hand ONLY, to splice-ready form similar to standard ribbon for fast and easy 12 fiber ribbon splicing (for both in-line and fusion splice-on connector splicing applications).
