چکیده
In this paper we present an experimental analysis of several modulation formats (pulse amplitude (PAM-2), quaternary pulse (PAM-4) and electrical duobinary (EDB)) for passive optical network (PON) applications at 25 Gbps bit rate in a C-band 10G-class directly modulated lasers (DML) avalanche photodiode (APD) intensity direct detection (IM-DD) system over single mode fiber (SMF) up to km, optimizing DML operations demonstrating that PAM-2 is promising choice. We also theoretically experimentally analyzed the channel frequency response SMF affected by chirp chromatic dispersion.

25 MHz clock continuous-variable quantum key distribution system over 50 km fiber channel
In this paper, a practical continuous-variable quantum key distribution system is developed and it runs in the real-world conditions with 25 MHz clock rate. To reach high-rate, we have employed a homodyne detector with maximal bandwidth to 300 MHz and an optimal high-efficiency error reconciliation algorithm with processing speed up to 25 Mbps. To optimize the stability of the system, several k...
متن کاملReal-time experimental demonstration of low-cost VCSEL intensity-modulated 11.25 Gb/s optical OFDM signal transmission over 25 km PON systems.
The feasibility of utilising low-cost, un-cooled vertical cavity surface-emitting lasers (VCSELs) as intensity modulators in real-time optical OFDM (OOFDM) transceivers is experimentally explored, for the first time, in terms of achievable signal bit rates, physical mechanisms limiting the transceiver performance and performance robustness. End-to-end real-time transmission of 11.25 Gb/s 64-QAM...
متن کامل100 Gbps IM/DD links using quad-polarization: Performance, complexity, and power dissipation.
A computational complexity, power consumption, and receiver sensitivity analysis for three different scenarios for short-range direct detection links is presented: 1) quad-polarization, 2) wavelength division multiplexing (WDM), and 3) parallel optics. Results show that the power consumption penalty associated to the quad-polarization digital signal processing (DSP) is negligibly small. However...
