4.0mm Downhole Optic Sensing cable

Product Introduction

4.0mm Dia. Downhole Optic Sensing Cable, the outer layer tube is made of 316L / A825 corrosion resistant stainless steel with wall thickness from 0.5mm to 0.71mm and the collaps pressure from 70MPa to 207MPa. Enough fiber excess length(FEL) ensure the optical fiber not subject to stress in the downhole working environment. The hydrogen scavenger fiber gel ensure the optical fiber attenuation stability. 4.0mm Dia. Downhole Optic Sensing Cable is usually used in Coiling Tube(CT) for temperature(DTS), acoustic(DAS) sensing system. It can also be used for downhole permanent installation.
