  • Publication number: 20130115803
    Abstract: A method is provided in one example and includes receiving a signal at an indicator activator provided on a first end of a data cable. The data cable comprises a second end that includes an indicator. The method also includes activating the indicator such that at least a portion of the data cable is illuminated. In more particular embodiments, the indicator activator is a switch, and the signal causes the switch to close such that a current is provided to the indicator.

  • Publication number: 20130058444
    Abstract: Techniques are provided for fault-tolerant communications over a two-wire interface. A method for such communications includes iteratively initiating transfer of data between a master device and a slave device via a two-wire interface, and, prior to each iteration, transmitting a flushing bit-stream from the master device to the slave device. The flushing bit-stream is configured to align the operations of the slave device with the operations of the master device.

  • Publication number: 20120263460
    Abstract: Adaptive power setting techniques for optical transceivers are provided. Optical signals are received at a first optical transceiver device that are transmitted from a second optical transceiver device. A receive power of the optical signals received at the first optical transceiver device from the second optical transceiver device is determined. A characteristic of optical signals transmitted by the first optical transceiver device to the second optical transceiver device is modulated to indicate to the second optical transceiver device a disparity of the receive power with respect to a target receive power level at the first optical transceiver device. Conversely, the first optical transceiver device adjusts a power level of optical signals transmitted by the first optical transceiver device to the second optical transceiver device based on a characteristic of the optical signals received at the first optical transceiver device.

  • Publication number: 20120250735
    Abstract: An apparatus includes a transceiver device mounted on a printed circuit board and configured to transmit and receive signals that comply with a 10GBASE-T standard. A pluggable connector is disposed at one end of the printed circuit board and is coupled to the transceiver device. The pluggable connector is configured to plug into an X2 system port to convey signals that comply with the 10GBASE-T standard between the transceiver device and a system device. A port device is disposed at an opposing end of the printed circuit board and is coupled to the transceiver device. The port device is configured to receive a transmission cable to convey signals that comply with the 10GBASE-T standard between the transceiver device and a network device.

  • Publication number: 20120254495
    Abstract: An apparatus includes a transceiver device mounted on a printed circuit board and configured to selectively transmit and receive signals at a first data rate or signals at a second data rate. An X2 form factor pluggable connector disposed at one end of the printed circuit board includes first and second pins that respectively convey signals at the first and second data rates between the transceiver device and a system device. A port device disposed at an opposite end of the printed circuit board conveys signals between the transceiver device and a network device. A management circuit determines which of the first and second data rates is selected based on transmissions between the system device and the network device and controls the transceiver device to transmit and receive signal at the first data rate via the first pins and at the second data rate via the second pins.

  • Publication number: 20120087675
    Abstract: An apparatus, in accordance with particular embodiments, includes an interface configured to establish connections within a copper network. The apparatus also includes a receptacle configured to receive a conventional small form-factor pluggable (SFP) module or a compact SFP module and to direct the SFP modules to a first connector. The first connector connects either of the SFP modules to the node. A pin of the first connector is configured to receive a module detection signal and to transmit data to the compact SFP module. The apparatus also includes a low pass filter coupled to the pin of the first connector that passes the module detection signal to the node. The apparatus is further configured to establish two duplex connections with an optical fiber network if the compact SFP module is connected and to establish one duplex connection with the optical fiber network if the conventional SFP module is connected.

  • Publication number: 20100325432
    Abstract: A method is provided, including (a) upon a standard small form-factor pluggable (SFP) module being inserted into an SFP jack on a network host device, determining if the SFP module is a legacy device or a smart device, (b) upon determining that the SFP module is a legacy device, receiving a magic code from the SFP module and determining if the magic code is a valid magic code, and (c) upon determining that the SFP module is a smart device, performing a smart authentication process with the SFP module. Associated apparatuses and additional methods are also provided.
