OMCannounces a new fibre optic emitter, designated the FDE854LBF, which joins next-generation infra-red die technology with integral micro-optics to achieve high levels of coupled power, integrated 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 and enhanced consistency from device to device, delivers an efficient 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 per cent 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.
William Heath, commercial director, OMC, comments: It is often overlooked that when talking about an optical emitter that can deliver additional intensity, there are additional advantages for other applications which do not demand that the device also delivers in terms of power saving and reduced heat generation and there can be applications where upgrading to the next generation device is appropriate purely on power saving grounds.
