Title (EN) A DSP-FREE 'COHERENT LITE' TRANSCEIVER FOR NEXT GENERATION 1 LAMBDA × 400G 10KM OPTICAL INTRA-DATACENTER INTERCONNECTS
(FR) ÉMETTEUR-RÉCEPTEUR DE LITE COHÉRENT SANS DSP D'INTERCONNEXIONS OPTIQUES INTRA-CENTRE DE DONNÉES 1 LAMBDA × 400G 10 KM DE PROCHAINE GÉNÉRATION
Abstract:
(EN) The disclosure relates to a transceiver operative to transmit and receive optical signals. The transceiver comprises a laser, a power splitter, a dual-polarization in-phase and quadrature modulator, DP-IQM, a first circulator (C1, C3), a second circulator (C2, C4), a first optical polarization controller, PC, a second optical polarization controller and a dual-polarization coherent receiver, DP-CRx. There is provided a system comprising a first transceiver and a second transceiver as described previously. The transceiver requires neither high speed DSP nor high resolution data converters to achieve 50 Gbaud DP-16QAM, DP standing for dual polarization and QAM standing for quadrature amplitude modulation, yielding 400 Gb/s over 10 km below the 2.2×10-4 KP4 forward error correction (FEC) threshold.
(FR) L'invention concerne un émetteur-récepteur conçu pour émettre et recevoir des signaux optiques. L'émetteur-récepteur comprend un laser, un diviseur de puissance, un modulateur en phase et en quadrature à double polarisation, DP-IQM, un premier circulateur (C1, C3), un second circulateur (C2. C4), un premier contrôleur de polarisation optique, un PC, un second contrôleur de polarisation optique et un récepteur cohérent à double polarisation, DP-CRx. L'invention concerne un système comprenant un premier émetteur-récepteur et un second émetteur-récepteur tels que décrits précédemment. L'émetteur-récepteur ne requiert ni DSP à grande vitesse ni convertisseurs de données à haute résolution pour obtenir 50 gbauds DP -16 QAM, DP prenant en charge une double polarisation et QAM prenant en charge une modulation d'amplitude en quadrature, produisant 400 Gb/s sur 10 km au-dessous du seuil de correction d'erreur sans voie de retour (FEC) de 2,2 × 10-4 KP4.
