SPIRIT at a glance...
SPIRIT aims to build a fully programmable transceiver in a single package for Terabit optical transport networks capable of superchannel grooming on a gridless basis and SDN functionality on board. The SPIRIT transceiver will support near future 400G implementation and forthcoming 1T traffic demands providing the necessary flexibility in modulation format by dynamic adjustment of single and multi-carrier QAM up to 16 bits/s/Hz spectral efficiency and multi-level modulation with 5-bit resolution driving electronics. Variable baud rates up to 32 GBaud will generate throughputs up to 512Gb/s on a single wavelength and 1Tb/s on two wavelengths on a single device.
In a nutshell, SPIRIT will deliver reliable optical components with a strong focus on rapid commercialization and key system specs:
§ Ultra-low power stemming from the revolutionary InP PATH modulator design. The total power consumption of the SPIRIT transceiver is estimated 14.4W.
§ Cost-efficiency due to the maturity of the InP, CMOS and SOI technologies. 40nm CMOS processing offers 50% cost reduction compared to competing silicon technologies.
§ Scalability enabled by the 5-bit arbitrary waveform generation offering the highest resolution to date at this baud rate.
SPIRIT is a 3-year collaborative project on photonic integration that brings together seven leading European universities, research centers and companies. The project was launched in December 2013 and is co-funded by the European Commission through the Seventh Framework Programme (FP 7).
