NRZ data with PRBS length 231 − 1, was propagated over 25 km of standard single mode fibre at a rate of 10 Gbit/s and 12.5 Gbit/s in a repeater-less transmission system. Results show that, for a received optical power of −13.2 dBm, the BER were 2.7 × 10−6 and 3.3 × 10−4 respectively, with sufficient margin below the FEC limit of 1 × 10−3 . The packaged transmitter comprised an integrated DFB laser, electro-absorption modulator and semiconductor optical amplifier hybrid integrated on silicon wafer.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for 2018 presentations, with transcripts for prior recordings added daily.
