    Vertical Shaft Smart Building Fiber Optic Cable Connection

    These specialized cables are engineered for vertical runs in riser shafts and elevator shafts, providing reliable connectivity while meeting strict fire safety codes. The indoor riser optic fiber cable features a design that balances transmission performance with fire resistance. It may consist of single-mode or multi-mode fibers based on distance and bandwidth requirements. Backbone cables may run through designated risers, conduits, or innerducts and should be rated for. A fiber optic riser cable—designated as OFNR, shorthand for Optical Fiber, Nonconductive, Riser—is a type of indoor fiber optic cable specifically designed for vertical installations. Although the capacity of these networks is in many cases sufficient for today's needs, there is a limitation in transmission distances with typical cable lengths. Fiber optic cabling ensures these devices stay connected with minimal latency, enabling efficient energy usage, improved security, and enhanced tenant comfort. The cable includes up to 24 fiber micro modules with each micro module containing 2/4/6colored fibers 250um.
