  • Publication number: 20080063407
    Abstract: A digital optical network (DON) is a new approach to low-cost, more compact optical transmitter modules and optical receiver modules for deployment in optical transport networks (OTNs). One important aspect of a digital optical network is the incorporation in these modules of transmitter photonic integrated circuit (TxPIC) chips and receiver photonic integrated circuit (TxPIC) chips in lieu of discrete modulated sources and detector sources with discrete multiplexers or demultiplexers.

  • Publication number: 20070122148
    Abstract: A method is disclosed for monitoring and controlling the bit error rate (BER) in an optical communication network where an optical receiver in the optical transmission network. The method includes the steps of decombining a combined channel signal received from the network and then monitoring a real time bit error rate (BER) of a decombined channel signal. The determined BER is then communicated, such as through an optical service channel (OSC) to an optical transmitter source that is the source of origin of the channel signal. Based upon the determined BER, the chirp of a channel signal modulator at the optical transmitter source that generated the monitored channel signal is adjusted by, for example, adjusting its bias. The same channel signal received at the optical receiver can be monitored again to determine if an acceptable level for the BER has been achieved by the previous chirp adjustment.

  • Publication number: 20070003281
    Abstract: A system, apparatus and method are described for deployment of a control loop between optical or electro-optical modules and a multiplexing module to provide a desired power profile of banded optical channel groups. The power output characteristics of the optical or electro-optical modules, the properties of the transmission paths of the banded optical channel groups, and other factors may be analyzed to allow the control loop to achieve the desired power profile on the banded optical channel groups. The control loop may adjust the output power on the optical or electro-optical modules so that the banded optical channel groups are delivered to an optical component, such as an optical multiplexer or photo-detector, having a particular optical power profile.
