Connections between floors, distributors or buildings have to be able to transport enormous quantities of data. R&M thus recommends using fiber-optic technology for backbone cabling. Depending on the transmission distances and required transmission speeds, the backbone is planned either with multimode fibers (OM2, OM3, OM4) or singlemode fibers (OS2). 

Solutions for fiber-optic cabling based on R&Mfreenet are available both with pre-terminated units and with products for splice applications. Installation is simplified thanks to the fantastic quick-mounting technology from R&M. In order to permanently minimize transmission losses, R&M places particular importance on maintaining the minimum bending radii and protecting the fibers. Both of these aspects are already included on R&Mfreenet solutions.
