From Loose Tube to Multicore: A Journey Through Fiber Cable Innovations

Starting with the first loose tube fiber optic cable of the 1970s, Loren Rapp, Sumitomo Electric Lightwave’s product line manager for fiber optic cable, highlights the key drivers in the evolution of cable design. Initial designs focused on providing protection for fibers being pulled in long-haul applications – either by hand across land or by boat in oceanic deployments – to enable telephone and fax services. The industry has come a long way from offering plain old telephone service (POTS), and fiber optic cable manufacturers have enabled every step of this evolution. Many of today’s cables are designed to pack more fiber in less conduit or ladder rack space for AI and machine learning applications. Some of the cable types discussed in this Fiber Focus episode include tight-buffered, central tube/slotted core, monotube, and microcable.
