Specific Jacket SMA-Connected TO-Can Package FPLD Transmitter

TITLE:<Specific Jacket SMA-Connected TO-Can Package FPLD Transmitter With Direct Modulation Bandwidth Beyond 6 GHz for 256-QAM Single or Multisubcarrier OOFDM upto 15Gb/s> Abstract—A specifically designed SMA connector with jacket signal pin configuration is used to connect the transistor outline can (TO-can) packaged Fabry–Pérot laser diode (FPLD) for enhancing its direct modulation bandwidth beyond 6 GHz. The direct modulation of such an TO-can/jacket-SMA packaged FPLD with a 256 quadrature amplitude modulation (QAM) and single subcarrier optical orthogonal frequency-division multiplexing (OOFDM) format data stream at carrier frequency up to 6 GHz is approached with 10 MSa/s symbol rate. The optimized 256-QAM data with error vector magnitude (EVM) of 1.5% and signal-to-noise ratio (SNR) of 32.5 dB are observed, corresponding to a bit error rate as low as and a highest carrier-to-noise ratio of 43.5 dB.
