UK contractor Radstone plc has launched a new laser-based fibre-optic media interface adaptor that is designed for use in hostile environments such as avionic and ground-mobile applications. Designated as the FA2MIA equipment, the new device makes use of an 850 nm short wavelength laser and either a 50/125 mm or 62.5/125 mm multi-mode fibre to extend the working distance for fibre channels up to a maximum of 500 m with enhanced noise immunity. Active temperature compensation is used to maximise laser performance down to temperatures as low as -40°C and the device features two independent channels and is billed as being suitable for dual-redundant connection installations. FA2MIA can be housed externally (in an IP54 rated enclosure) with its electric connections accessible from inside the enclosure and its optical ones from outside it.
