Toneable Mini LT Drop Cables, two 100% dry options f

Similar to other optical fiber drop cables on the market, the

feature a flat, primarily dielectric construction. However,

construct the core for these cables, up to six optical fibersded within a 2 mm, totally dry polymer extrusion. Two

rods are then placed longitudinally alongside the dry co

For aerial self-supporting installations, OFS recommends

the standard Mini LT Flat Drop Cable, which features a

compatible with standard aerial drop wire clamps (i.e., no cable coils
