Corning® RCBI Optical Fiber

Corning® RCBI Optical Fiber

Corning understands the changing needs of the telecom industry. Fibers must have the capacity to reliably handle steadily increasing information at higher data rates, in an ever-decreasing footprint. Reducing the glass cladding diameter of a fiber can enable a significant step-change in package size. As module packages shrink in response to these changes, long lengths of fiber are deployed in permanently bent configurations, requiring consideration of the optical and mechanical impact of continuous, tightly wound coils. That is why we designed our new reduced-clad fiber specifically to be bend insensitive.

The new Corning RCBI optical fiber is the first reduced-clad fiber compatible with G.657 and G.652. This bend insensitive fiber features a thin cladding diameter of 80 microns. RCBI offers outstanding optical components with low attenuation, superior macrobending performance, and industry-leading geometry to continually pursue smaller packaging.
