NuSENSOR 1550 nm Bend

Insensitive Single-Mode Fibers

Coherent's NuSENSOR bend-insensitive single-mode fibers are highly engineered to be micro and macro bend resistant for

Raman, Brillouin and FBG based temperature and strain measurements at 1550 nm. These 0.12 NA, bend-insensitive single

mode fibers provide tight tolerance optical and geometrical specifications measured at the application critical wavelengths.

The fiber comes with either a polyimide or mid-temperature acrylate coating and are also available with a hermetic carbon

layer. The hermetically carbon-coated layer is immune to the damaging effects of hydrogen ingression, enabling distributed

temperature and strain sensing in harsh environments where high H₂ partial pressure and elevated temperatures up to

300°C are present.

Typical Applications

• Enhanced oil recovery processes

• Hydrothermal well temperature

measurements

• Oil reservoir optimization

• Brillouin distributed temperature &

strain sensing

Features & Benefits

• Bend-Insensitive core design — Minimizing micro and macro bend loss

• Exceptional uniformity — Consistent and repeatable performance

• Long unattended deployments or short cycle in-out applications

• Low loss over the wavelengths range critical to DTSS & FBG sensors

• Available with hermetic carbon coating — Enabling resistance to H₂ ingression, low cost and long life deployment
