  • Patent number: 9036990
    Abstract: A multi-channel optoelectronic device is configured to establish a redundant status link with a remote device. The optoelectronic device can transmit N transmit optical signals to the remote device over a plurality of transmit channels and receive N receive optical signals from the remote device over a plurality of receive channels. The optoelectronic device includes one or more spare transmit and receive channels. When used with a remote device having spare transmit and receive channels, each device can establish a status link with the other and use the status link to switch out transmit and/or receive channels to identify and permanently switch out the worst transmit and/or receive channels. Alternately, the device can interoperate with a non-status-link enabled remote device by determining that the remote device is not status-link enabled, transitioning to a low transmit power mode, and transmitting and receiving over a plurality of default transmit and receive channels.

  • Patent number: 8769171
    Abstract: A device having a plug that is configured to mechanically interface with a receptacle external to the device. The plug also has an electrical interface that electrically interfaces with the receptacle even though the external receptacle has a mechanical and electrical interface shaped to interface with an integrated cable that includes an optical communication mechanism for communicating over most of the length of the integrated cable, and even though the device itself has a full electrical communication channel communicatively coupling a data communication endpoint of the device with the electrical interface of the plug.

  • Patent number: 8526810
    Abstract: An integrated cable configured to communicate over much of its length using one or more optical fibers includes an electrical connector at least one end. The electrical connector at a first end of the integrated cable and an optoelectronic device coupled to or included in the other end of the integrated cable may utilize a bidirectional status link to transmit status data to each other. If the status data indicates that optical signals transmitted over the optical channels between the two devices are not potentially exposed to view, the two devices may operate above nominal eye safety limits. Otherwise, the two devices may operate at or below nominal eye safety limits. If the second optoelectronic device is not status-link enabled, the first optoelectronic device may operate at or below nominal eye safety limits.

  • Patent number: 8244085
    Abstract: Systems and devices using diffractive and optionally refractive elements to launch an optical signal with a controlled amplitude and phase distribution into a multimode optical fiber for improved modal dispersion are provided. More particularly, optical ports, transmitter optical subassemblies (TOSAs), and transceivers use integrated diffractive and optionally refractive elements to launch a helically propagating light distribution, also known as a vortex launch. One embodiment includes a monolithic transparent port that generally includes: a lens on a first surface for receiving and collimating or focusing an optical signal; and a diffractive surface pattern for receiving the optical signal from the lens and launching the optical signal into a multimode optical fiber with a controlled intensity and phase distribution. Alternatively, the lens can be added as a separated component or omitted altogether while the diffractive surface pattern is formed on either the laser or fiber receptacle sides of the port.

  • Publication number: 20120020674
    Abstract: A robust and redundant status link is established by a first multi-channel optoelectronic device with a second multi-channel optoelectronic device in a multi-channel communication link. Transmitter bias currents are effectively modulated with a status link modulation signal representative of status data and subsequently modulated with primary data modulation signals. The resulting signals are transformed into optical signals and transmitted over the link as main communication links combined with a status link. At the second device, the optical signals are received and converted to electrical signals. The receipt of the optical signals creates multiple receiver bias currents, which may be monitored to detect the status link modulation signal. The second device may adjust various operating parameters in response to the information conveyed by the status link.
