Slotted optical packet switching (OPS) is foreseen as future technology for intra datacenter network that will have to provide dynamic reconfiguration capacity, scalability, low latency and QoS guarantees to support fast growing emerging services. In this paper, we describe a prototype based on this technology and reconfigurable thanks to implementation of Software Defined Network (SDN) functions...
We show the first hitless 100Gbit/s real-time bandwidth-variable transmitter integrated with restful server and OTN switching matrix. Between 10.7Gbit/s and 107Gbit/s, the transmitter reconfigures in less than 450μs without packet loss and additional penalty.
The operation of multi-domain and multi-vendor EONs can be achieved by interoperable Sliceable Bandwidth Variable Transponders, a GMPLS / BGP-LS-based control plane and a planning tool. This paper reports the first full demonstration and validation this end-to-end architecture.
A real-time FPGA-based receiver of 21Gb/s PS-QPSK signal is reported and tested against optical noise, chromatic dispersion (CD), polarization mode dispersion (PMD) and state of polarization (SOP) scrambling. A comparison with PDM-QPSK realized with equivalent parameterized setup and signal processing confirm the greater tolerance of PS-QPSK over PDM-QPSK.
We present the first prototype of a real-time bandwidth-variable coherent muxponder aggregating multiple 10GigE clients onto a symbol-rate-variable PDM-QPSK optical signal. This technology enables optical transport with power consumption linearly proportional to the actual requested traffic.
We experimentally show a real-time coherent receiver operated in burst mode. Enabled by special headers, 28-Gb/s PDM-QPSK packets with random states of polarizations are successfully demodulated, and the sensitivity to optical noise is reported.
A fully reprogrammable coherent receiver using an integrated coherent front end, four high speed ADCs and powerful FPGAs is reported and tested against optical noise level, chromatic dispersion and PMD for various equalizer filter length.
We achieve full real-time operation of 28 Gb/s burst-mode PDM-QPSK coherent receiver capable of handling packet-to-packet jitter and polarization wandering. The receiver is demonstrated with subwavelength switching in a four-node WDM optical packet network testbed.
We transmit 96 PDM-QPSK channels at 100Gb/s over 11,680km, matching the best capacity × distance product reported, but with C-band-only EDFAs. 2.7b/s/Hz spectral density is obtained, despite 23% super-FEC overhead, with optical spectral engineering.
We report on experimental long-haul transmission of 28Gaud PS-QPSK signal in a WDM scenario. We compare its performance with that of 28Gbaud PDM-QPSK signal and demonstrate it could be interesting into software-defined optical transceivers.
We report the transmission of 155 channels with 100Gbit/s PDM-QPSK modulation over 7200km of pure silica core fibre, exploiting hybrid Raman-EDFA amplification and digital coherent detection. A record 112Petabit/s·km capacity×distance product is demonstrated.
The alternate polarisation-RZ-DPSK modulation format extends the 43 Gb/s unrepeatered transmission distance to 505 km, with E-PSCF fibre, third-order Raman pumping and a remotely-pumped amplifier.
In this paper, we present the design, fabrication and measurements of an ultra broad band amplifier with 92 GHz cut-off frequency intended for ETDM transmission applications over 40 Gbit/s. The circuit is based on InP double channel HEMT technology developed in OPTO+ to get high frequeny-breakdown voltage product. We will discuss the use of coplanar wave-guide lines and low impedance bias micro-strip...
