This is due to the fiber having such a small cross section that only the first mode is transported. The first single-mode optical fiber was developed by researchers Robert Maurer, Donald Keck, and Peter Schultz at Corning Glass Works in 1970. By lowering the fiber core diameter and optimizing the refractive index difference between the core and cladding, they achieved single-mode transmission for.

Now that we understand the need for high-fiber-count cables, we can turn our attention to the alternatives on the market for data center interconnect. Traditional loose tube cables and single-fiber splicing would take much too long to install and re. Once the industry determined that ribbon cableswere the best option, it was quick to realize that traditional ribbon cable designs were not able to achieve the required fiber density in existing conduit.
