Micro-cluster indoor optical cables are used for vertically laying optical cables at indoor user access points and between floors. The dry design is easier to weld. According to the number of. The cable uses multi-core units (fiber optic, Micro Cluster Group) and non-metalic core stifeners. An external mark of the sheath indicates the. The Fiber Port Clusters are compact opto-mechanical units that combine two fiber-coupled sources with differing wavelengths and then splits the combined radiation into multiple output fiber cables with high efficiency and variable splitting ratio.
