AMETEK SCP Glass-Sealed FOFT Works in Extreme Pressure or Temperature Applications

As oil and gas producers push technology to ever-greater ocean depths to find sources of supply, there is an increased need for long-distance, high-temperature, and high-pressure sensors and communications devices. AMETEK SCP has developed the technology to produce a glass-sealed fiber optic feedthru (FOFT) for extreme high-pressure, high-temperature applications.

AMETEK developed the FOFT to meet the harsh downhole environments encountered in the drilling and completion of oil and gas wells, and customers have qualified it for 30,000 psi and 300oC. The FOFT is currently configured for one to eight fibers in a 0.375-inch housing that can be welded or coupled with a standard high-pressure fitting. The FOFT also has been miniaturized to fit a high-pressure, high-temperature connector.

This rugged, high-performance fiber optic feedthru is constructed of low-outgassing materials and configurable with standard single-mode and multi-mode fibers. It conveniently interfaces with standard 3/8” high-pressure fittings and is available in a variety of optional end terminations, including bare, stripped, SMA, ST, FC, APC, and custom ferrules.

AMETEK’s unique process produces a hermetic seal between an optical fiber and a metal super alloy with a proprietary seal glass. The result is an extremely durable compression seal that can withstand extreme temperatures and pressures. The connector’s robust construction also makes it highly resistant to corrosion and chemical attack. No other optic-fiber-based feedthru in the industry offers the same combination of characteristics and performance for harsh service conditions.

Applications include oil and gas downhole tools; high-pressure and temperature optical detector flow cells; and submarine pressure hull penetrators, compartment bulkhead connectors, and dry mate systems.
