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 was previously unavailable in a high-density, reduced-footprint, multi-channel option,” explained Mark Matus, Global Product Manager, Molex. “The Hermetic-Sealed Multi-Fibre Circular MT Optical Assemblies ensure industry-leading gas-tight-sealing for superior performance.”
Hermetic-Sealed Multi-Fibre Circular MT Optical Assemblies contain 12 to 24 flat-ribbon fibres in one connector, featuring a small footprint in comparison with similar products that utilise discrete-fibre (one fibre per contact) connector designs. The connectors also feature sealing rates to 1×10-6 helium cc/s at one atmosphere differential pressure.
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, and both single- and multi-mode fibre options are available.
