Efficient Digital Coherent Detection of A 1.2-Tb/s 24- Carrier No-Guard-Interval CO-OFDM Signal by Simultaneously Detecting Multiple Carriers Per Sampling
Coherent communications Phase modulation
2015/6/10
We experimentally demonstrate efficient detection of a 1.2-Tb/s 24-carrier NGI-CO-OFDM signal with 12.5-Gbaud PDM-QPSK carrier-modulation by simultaneously recovering 2 or 3 carriers per 50-GSamples/s...
Cost-effective WDM-PON for Simultaneously Transmitting Unicast and Broadcast/multicast Data by superimposing IRZ signal onto NRZ signal
Cost-effective WDM-PON Simultaneously Transmitting Unicast Broadcast/multicast Data
2015/8/3
We propose a novel WDM-PON broadcast/multicast architecture that superimposes inverse-RZ signal onto NRZ unicast signal. Multicast control is realized through extinction ratio adjustment of the NRZ si...
