VHT5000 Multimode Series
Features:
- Best glass resistance to hydrogen at high temperatures and pressures available in the entire industry
- High bandwidth 50/125 graded-index multimode design for extremely short spatial resolution in sensing applications
- Metal coating protects the fiber at temperatures up to 500°C
- Patent-pending process prevents fibers from “cold bonding” to metal tubes or other metallic-coated fibers
- Suitable for use in high pressure, high temperature and corrosive environments
- Available in long lengths (multi-kilometers)
- Industry-standard 125 μm clad diameter
- Extensive test and measurement data for optical fiber performance under "harsh conditions" provided with fiber
- Available in a 500°C cabled solution (see below in Documents)
PRODUCT DESCRIPTION
Verrillon Harsh Environment Fibers from AFL are available in a wealth of designs. The VHT5000 product is a multimode graded-index optical fiber with optimized glass chemistry for high resistance to hydrogen darkening, coupled with a metal coating that allows the fiber to perform at temperatures up to 500°C. Typically, these fibers are used in down-hole data logging for enhanced supercritical geothermal applications, high-temperature oil/gas downhole sensing and in downstream oil processing.
