Abstract
Duplex operation in the local network is a very attractive technique especially when using optoelectronic integrated devices (OEICs). The authors deal with duplexer requirements directed to insertion loss, near-end and far-end crosstalk attenuations, obtained by calculations of duplexer crosstalk induced penalties considering transmission loops with OEICs (laser diode, photodiode and duplexer on one semiconductor chip). The calculations are based on a worst case optical power budget including losses due to waveguides, laser-waveguide couplers, chip-fiber couplers, fiber etc.
