Optical packet switching (OPS) subsystems have a crucial role in current optical access networks and may be essential in future access and datacenter networks, where the requirements for higher data-rates, transparency, reduced end-to-end latency and optimized energy consumption may be enabled by increasing the network granularity and introducing flexibility on both the line-rate and the modulation...
We experimentally demonstrate a novel coherent optical packet switching architecture for data center networks. This architecture uses coherent polarization-division multiplexed QPSK modulation to increase the capacity and relies on self-homodyne transmission for automatic tuning of the receiver LO. Information bearing packets and pilot tone signals are routed thought separated arrayed wavelength gratings...
We demonstrate the operation of an optical packet switching node with buffering for 12.8-Tbit/s polarization and wavelength division multiplexed, 16-QAM optical packets after 50-km of fiber transmission. Processed optical packets were recovered by an offline burst-mode optical coherent receiver while keeping BER below FEC limit.
We demonstrated an optical packet switching node with buffering capabilities for polarization division multiplexing (PDM)-16QAM, DWDM optical packets. Over 10-Tbit/s wideband optical packets were handled by PLZT-based optical switches and demodulated by an offline, coherent burst-mode optical coherent receiver.
In this letter, an analog-to-digital converter (ADC) that is typically employed in current state-of-the-art high bit rate lightwave communication systems experiments is characterized for a broad range of input powers in order to develop a reliable model for simulation purposes. We show that the receiver performance is dominated by the digitizer noise, especially at low powers. This is particularly...
We demonstrate an NRZ multi-rate digital receiver capable of receiving upstream TDM traffic line-rates from GE-PON to 10GE-PON, that utilizes a simple optical front end and polyphase DSP at 2 samples per bit.
A centralised optical processing unit that functions both as a wavelength converter and optical burst equaliser in a 10Gbit/s wavelength-converting optical access network is proposed and shown to extend the system dynamic range to 14.3dB.
