Called FDE851HLBF, it emits at 850nm and comes in a TO-can with glass window to protect the device from the atmosphere.
Long-term reliability is the reason for the sealed package.
“Many fibre-optic emitters make use of a clear plastic cap which is pressed on to the device header,” according to the firm. “While this provides an element of physical protection to the LED chip, wire-bond and internal optics, it is unusual for such a cap to provide a hermetic seal, meaning that the potential long-term effects of environmental characteristics such as humidity must be carefully considered in applications where long service-life is important.”
Rise and fall times are sufficient for operation at tens of MHz, and integrated micro-optics are provided to couple light into multi-mode glass optical fibres as small as 50µm – Typical launch power is 30µW at 100mA into a 50/125 fibre.
This part will be on show on stand J100 at Southern Manufacturing & Electronics at the Southern Manufacturing & Electronics show next week, alongside another new emitter from OMC – the FDE2850 which is optimised for 200µm glass fibre.
Also there will be a ‘shield’ for interfacing Arduino Unos to optical fibres – called the H19 Fibre Optic Shield.
“Southern Manufacturing & Electronics is an excellent showcase for us in the UK and provides the opportunity to put our latest products in front of potential new customers early in the year,” said OMC commercial director William Heath.
OMC is a UK manufacturer based in Cornwall. It was founded in the mid-1980s as The Fibre-Data Group.
