We demonstrate compact and low-loss $8 \times 8$ silicon photonic switch modules, which are applicable to transponder aggregators (TPAs) in colorless, directionless, and contentionless reconfigurable optical add-drop multiplexers. Newly designed sili

C-band and L-band wavelength division multiplexing (WDM) transmission performance was improved by using bidirectional signal assignment (BSA) to reduce crosstalk (XT) in square lattice structure 16-core fiber. Transmission of 16 WDM channels with 256

For the first time native IP data are carried end-to-end by 100 GE router interfaces and a 100 G optical transport system over 1520-km field deployed fiber. This is accomplished with multi-suppliers' 112-Gb/s single carrier real time coherent DP-QPSK

We propose a high-speed protection scheme for multiple-priority-class traffic transmission in WDM ring networks. This scheme achieves high-speed protection by quickly suspending transmission of low-priority traffic when a failure is detected. Each no

We demonstrated experimentally the improvement of the transmission distance by 27% of 150Gb/s signal at 3b/s/Hz with a novel TCM format, 8-state 12QAM TCM, compared to PM-8QAM. We also demonstrated improvement of the transmission distance for multipl

We propose a new 4D coded modulation format, 64SP-12QAM, with same SE as PM-8QAM and straightforwardly-switchable with PM-16QAM. We experimentally demonstrated over 0.2 dB better sensitivity for 64SP-12QAM compared to PM-8QAM, enabling a transmission

We demonstrate crosstalk reduction using bidirectional signal assignment on WDM transmission of 256 Gb/s PM-16QAM over square lattice structure 16-core fiber. Mixed SSMF and MCF transmission with 6 spans of MCF is possible with Q crosstalk penalty be

We propose multi-redundancy optical coded modulation using superposed trellis. We experimentally prove that our scheme enables fine adaptive SE control and high coding gain of 7.1dB for 3-bit redundant 16QAM with quarterly reduced circuit complexity.
