652 fiber has a step-index refractive index profile, which means that there is a distinct step change in refractive index between the core and cladding. This document outlines the specifications for a single-mode optical fiber and cable designed for use around the 1310 nm zero-dispersion wavelength, suitable for both the 1310 nm and 1550 nm regions, and compatible with analogue and digital transmission. It details the fiber's geometrical, optical. G. Parameters are subject to change without notice. No point discontinuity greater than 0. ro Dispersion Wavelength Zero Dispersion Slope Typical Value 131“Leviton is dedicated to designing, developing and manufacturing sustainable high performance structured cabling and specialty cabling solutions. ” The information contained in this document is valid and correct at the time of issue.
