Abstract

We report here the development of a multiplexer-demultiplexer for WDM transmission systems. The device is capable of multiplexing 5 distinct wavelength LEDs at centre wavelengths of 0.75, 0.87, 1.06, 1.30 and 1.55μm using multimode optical fibre. Insertion losses of less than 1dB have been obtained while isolation between all channels is better than -20dB, typically better than -25dB. Devices have been temperature cycled over the range +125°C to -55°C with only ±0.3dB variation in insertion loss. No measurable change in insertion loss was seen when the device was vibration tested over the range 10Hz to 2KHz (10g) or shock tested in all 3 axes.
