Abstract
A data communication system includes a novel transceiver which uses different transmit and receive data symbol lengths enabling the transceiver to operate in a full-duplex mode. The transceiver transmits data of a first type over a communication link during a first time period, and receives data of a second type over the link during a second time period which is longer than the first time period and which overlaps a portion of the first time period. In one embodiment, the transceiver switches a transmitting means to the link during the first time period and connects a receiving means to the link during a portion of the second time period which does not overlap the first time period.
Claims26
A transceiver for transmitting and receiving data over a communication link, comprising
- means for transmitting data of a first type over the link during a first time period,
- means for receiving data of a second type over the link during a second time period which is longer than the first time period and which overlaps a portion of the first time period, and
- wherein the first and second types of data cannot be separated at the transceiver on the basis of a spectral content of signals representing the first and second types of data.
An optical transceiver for transmitting and receiving data over a communication link, comprising
- means for transmitting data of a first type over the link during a first time period,
- means for receiving data of a second type over the link during a second time period which is longer than the first time period and which overlaps a portion of the first time period.
A full-duplex data communication system including a master and a slave transceiver for transmitting and receiving data over a communication link, comprising
- at the master transceiver,
- first means for transmitting to the slave transceiver data of a first type over the link during a first time period,
- second means for receiving from the slave transceiver data of a second type over the link during a second time period which is longer than the first time period and which overlaps a portion of the first time period,
- at the slave transceiver,
- third means for transmitting to the master transceiver data of the second type over the link during the second time period,
- fourth means for receiving from the master transceiver data of the first type over the link during the first time period,
- wherein at both the master and slave transceivers, the first and second types of data cannot be separated on the basis of a spectral content of signals representing the first and second types of data.
A full-duplex optical data communication system including a master and a slave optical transceiver for transmitting and receiving data over a communication link, comprising
- at the master transceiver,
- first means for transmitting to the slave transceiver data of a first type over the link during a first time period,
- second means for receiving from the slave transceiver data of a second type over the link during a second time period which is longer than the first time period and which overlaps a portion of the first time period,
- at the slave transceiver,
- third means for transmitting to the master transceiver data of the second type over the link during the second time period, and
- fourth means for receiving from the master transceiver data of the first type over the link during the first time period.
A method of operating a transceiver for transmitting and receiving data over a communication link, comprising the steps of
- transmitting data of a first type over the link during a first time period, and
- receiving data of a second type over the link during a second time period which is longer than the first time period and which overlaps a portion of the first time period, the second type of data being such that it cannot be separated from the first type of data on the basis of a spectral content of signals representing the first and second types of data.
