OMC, the pioneer in optoelectronics design & manufacture, announces a new fibre optic emitter designated the FDE854LBF, which incorporates next-generation infra-red die technology and integral micro-optics to achieve high levels of coupled power into all standard fibre-optic core sizes. The new transmitter is optimised for use with glass fibre-optic systems and thanks to both higher launch powers (up to 30% increase over the previous device generation) and enhanced consistency from device to device, delivers far superior performance, enabling data to be sent over greater distances – up to a kilometre further depending on fibre type and size.
A further advantage offered by the higher launch power of the FDE854LBF is its ability to be driven at up to 30% lower currents for applications that do not require the additional launch power. In a large installation, involving 20,000 to 30,000 channels for example, the resulting power saving can be several kilowatts, helping the application to meet environmental criteria, while reducing power supply requirements and heat generation. This feature is also very useful for applications drawing power from batteries, renewables, or those in a restricted power environment. The reduction in generated heat can be helpful in designs where heat buildup can be problematic, such as enclosed, space-restricted applications or where there are sensitive components used on the same PCB. Under driving to save power also prolongs the life expectancy of the system.
