drilling and completion of oil and gas wells. It has been qualified for 30,000psi and 300ºC. The FOFT is currently configured for one to eight fibers in a 0.375" housing that can be welded or coupled with a standard high-pressure fitting. The FOFT has also been miniaturized to fit a high pressure, high temperature connector. This rugged, high performance fiber optic feed thru is constructed of low outgassing materials and is 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.

seal. The connector’s robust construction also makes it highly resistant to corrosion and chemical attack. It is believed to be the only optic fiber-based feed thru in the industry to offer its combination of characteristics and performance for harsh service conditions.

Polyolefin to replace PVC

Addivant™ USA LLC has introduced new Polybond ® polymer modifiers that allow halogen-free polyolefin compounds to replace PVC in flame retardant wire and cable. The replacement of PVC in wire and cable insulation and jacketing is driven chiefly by regulatory changes. This has developed an increased demand for halogen-free polyolefin compounds for use in transportation, electrical and electronic, building and construction and appliance applications. Polyolefins are the most widely used polymers, primarily due to their ease of processing, balance of mechanical properties versus cost and, with respect to the wire and cable market, good electrical properties, but they are not inherently flame retardant. Traditional formulations to make polyolefins flame retardant use halogenated flame retardants, which in turn

Ametek’s process produces an hermetic seal between an optical fiber and a metal super alloy with a proprietary seal glass. The result is an extremely durable compression
