High-speed Fading-free Direct Detection for DoubleSideband OFDM Signal via Block-wise Phase Switching
High-speed Fading-free Direct Detection Double Sideband OFDM Signal Block-wise Phase Switching
2014/11/6
We employ phase switching of either main-carrier or subcarriers of two consecutive signal blocks for double-sideband fading-free direct-detection (DD). In so doing, 40-Gb/s DDOOFDM is successfully rec...
A Bidirectional 2×2 Photonic Network Building-Block for High-Performance Data Centers
Networks Optical interconnects
2015/5/22
The design of a unique bidirectional 2×2 SOA-based optical switch is detailed and experimentally validated. Error-free operation and routing correctness is verified for 4×10Gb/s pseudorandom messages.
43Gb/s CP - QPSK Realtime Receiver Demonstrator based on FPGAs and Block - Processing
Realtime Receiver Demonstrator FPGAs Block - Processing
2015/7/16
We present measurement results of an FPGA-based 43Gb/s Realtime Coherent Receiver Demonstrator. Due to limitations we use block-aggregation and process 1/32 of the input data stream. We show back - to...
