摘要: A 10-Gb/s optical transceiver using the Yuen 2000 (Y-00) encryption protocol was developed. The key device in transceiver, a 10-GS/s, 10-bit digital-to-analog converter (DAC) LSI, fabricated 0.25-μm SiGe BiCMOS technology. Circuit techniques such as segmented architecture, parasitic capacitance separation base-common transistor, and usage of common mode logic (CML) driver were employed to minimize glitches. Y-00 equipped with DAC LSI operated at 10 Gb/s. Moreover, 300-km transmission experiment performed data rate Gb/s proved that developed can be used practical application when forward error correction is applied.
