Abstract
A system (50) includes a communication path (170) and transmits data on a network (103, 106). A transmitter (101) transmits data on the network and a receiver (112) receives data from the network. A component (102, 114) in the communication path has a transfer characteristic (C1, C2, C3) adjusted in response to errors in data transmitted over and received from the network in order to reduce the error rate.
Claims19
An optical fiber communications network transceiver, comprising:
- a transmitter having a characteristic that is adjusted by a control signal;
- a module operatively coupled to the transmitter and arranged to analyze data to generate one or more error signals responsive to errors in the data, the module being configured to receive the data on parallel data lines at a first data rate and to send the data to the transmitter on a single serial line at a second data rate that is greater than the first data rate;
- and
- a media access controller operatively coupled to the module and responsive to the one or more error signals arranged to generate the control signal to adjust the characteristic of the transmitter,
- wherein the data flows from media access controller to the module to the transmitter before being transmitted, and
- wherein the module comprises a first clock and data recovery circuit used in the data flows from the media access controller to the module to the transmitter.
