Product Introduction

Type LT-500 is designed for large-core optical fiber ribbon cable. The loose tube of optical fiber ribbon cable is made a large diameter and does not drip. It is also needed to use higher viscosity and small penetration (thick pasty fluid). As a result, it is hard to filling in the optical fiber (bundle) or gaps of optical fiber, which leads to reduce the information that optical fiber transfer and effects transmission quality.


Cold application type LT-500 optical fiber coating paste technical specification


Filling gel is needed to be homogeneous, hydrogen absorption, and does not include any dust, metal particles, and other impurities. It should be no sight visible air bubbles, and the mold should be no nutrition. Filling gel should be non-toxic, no stimulation to the skin.
