6.35mm Downhole Optic Sensing Cable

Product Introduction

    Downhole Optic Sensing Cables (DOSC), with 316L/A825 used in the outer layer, pressure resistance of 30,000 psi (207Mpa).Unique solution for applications > 150℃ is a three layer design with the secondary layer being 0.040" thick aluminum.

Literature indicates hydrogen permeability through aluminum is 100 times less than stainless steel resulting in an extended life for the optical fiber. DOSC with 0.3% excess fiber length (EFL) ensures no stress on optic fibers during operation conditions; hydrogen scavenging gel promises stable optic fiber attenuation.
