OCDMA receiver with built‐in all‐optical clock recovery
View through CrossRef
A receiver that incorporates an all‐optical clock recovery approach for synchronisation suitable for use in incoherent OCDMA transmission is demonstrated. The developed solution was implemented and tested in a multiuser environment using the 2D‐WHTS coding scheme on incoherent OCDMA transmission with 2.5 Gbit/s data rate. The receiver with built‐in all‐optical clock recovery was tested by taking the BER for the received data when synchronised with the all‐optically recovered clock from the incoming OCDMA traffic and when an RF synthesiser was used to the generate the clock. Improvement of ∼7.5 dBm was observed with the all‐optical clock recovery approach. The related eye diagrams and the wavelength spectrum were also recorded.
