These conditions can cause ordinary surveillance and sensor equipment to fail, which can create critical communications problems. Hermetic sealing can address this problem, but only under certain circumstances. “Hermetic sealing for fibre optic connections has historically been limited to large, single-channel applications and until now was unavailable in a high-density, reduced-footprint, multi-channel option,” explains Mark Matus, global product manager, Molex. “The Hermetic-Sealed Multi-Fibre Circular MT Optical Assemblies, which are designed for critical use applications where long-term system reliability in harsh environments is critical, ensure gas-tight-sealing for superior performance.”

Hermetic-Sealed Multi-Fibre Circular MT Optical Assemblies contain 12 to 24 fibres in one small-footprint connector compared with similar products that utilise discrete-fibre (one fibre per contact) connector designs.

The assemblies are appropriate for applications that require optimal environmental and pressure-sealing capabilities, such as aerospace and defence, mining, oil and gas exploration, industrial process control, and medical. They can operate in temperatures ranging from -40° to 70° C.

A Multi-Fibre MT interface with 12 to 24 flat-ribbon fibre counts provides the densest fibre count in a compact hermetic interface for maximum data transfer. This suits the HSMFC MT Optical Assemblies for tight panel configurations where space is at a premium.

Sealing rates to 1×10-6 helium (He) cc/sec at one atmosphere differential pressure.

Stainless steel connector housings, which provide high durability and corrosion resistance.

Conduit fibre protection is available when superior crush resistance and extended sealing capabilities are required.

Singlemode and multimode fibre options are available.
