Abstract: A Quad Small Form-Factor Pluggable (QSFP) transceiver module is provided that is configured to interface with a QSFP host and to send and receive a plurality of data signals at a data rate of up to forty gigabits per second (40 G). A plurality of 10GBase-T ports with Registered Jack (RJ) 45 connectors is also provided, wherein each of the 10GBase-T ports is configured to interface with a 10GBase-T device to send and receive a plurality of data signals at a data rate of ten gigabits per second (10 G). Cables are configured to interface with the QSFP transceiver module and with corresponding ones of the 10GBase-T ports with the RJ45 connectors. Each of the plurality of cables operates as a data channel for data flow between the QSFP transceiver module and the corresponding ones of the 10GBase-T ports with the RJ45 connectors.

Abstract: Techniques are provided for sending and receiving data communications between an enhanced Quad Small Form-Factor Pluggable (QSFP+) transceiver module and an enhanced Small Form-Factor Pluggable (SFP+) transceiver module. An adapter device is provided that has a first set of signal pins configured to interface with an SFP+ transceiver module and a second set of signal pins is provided that is configured to interface with a QSFP+ host port. A retimer unit is also provided that is configured to modify a 10G signal of a first electrical signal standard associated with the SFP+ transceiver module to a 10G signal of a second electrical standard associated with a QSFP+ transceiver module and to enhance a 10G signal of the second electrical signal standard to a 10G signal of the first electrical signal standard.

Abstract: An optics module sends, to a host module, a pin signal indicating that an optics module is plugged into the host module, wherein the optics module is configured to operate at at least a first data rate and a second data rate. The optics module receives, from the host module, an indication of a host data rate. The optics module determines whether there is clock and data recovery loss of lock between the first data rate and a host data rate. If it is determined that there is clock and data recovery loss of lock between the first data rate and the host data rate, the optics module initializes at the second data rate if the second data rate matches the host data rate.

Abstract: A dual rate transceiver may be provided. First, a host data speed of a host device may be detected. Then a last know data speed of a transceiver may be determined. Next, it may be determined that the host data speed and the last know data speed are different. And in response to determining that the host data speed and the last know data speed are different, the transceiver may be reconfigured to operate at the host data speed.
