Optical transmitter including a linear semiconductor optical amplifier

Abstract: An improved optical transmitter comprises a vertically lasing semiconductor optical amplifier (VLSOA) coupled to an external modulator and/or a laser source. The VLSOA, external modulator and laser source are discrete devices or alternatively integrated onto a common substrate. The integrated optical transmitter may be fabricated using a number of different methods, including based on selective area epitaxy, impurity induced disordering, etch and fill and silicon optical bench.

Simplified and shortened parallel cable

Abstract: One embodiment includes a connector comprising a connector housing, a ferrule, and a crimp ring. The connector housing has inner and outer surfaces extending between forward and rear ends of the connector housing. The inner surfaces defined a passageway extending lengthwise between the forward and rear ends. The connector housing includes at least one protrusion formed on one of the outer surfaces that is configured to engage a corresponding connector engaging structure of an alignment guide to secure the connector housing within the alignment guide. The ferrule is configured to mount upon end portions of a plurality of optical fibers of a multi-fiber communication cable. The ferrule is disposed partially within the passageway. The crimp ring encompasses the rear end of the connector housing and is configured to secure the connector to the multi-fiber communication cable.

Pad architecture for backwards compatibility for bi-directional transceiver module

Abstract: Exemplary embodiments of the present invention selectively adapt the pad architecture on bi-directional opto-electronic transceiver modules to connect to legacy unidirectional ports, panels and the like. This allows the bi-directional module to function correctly when connected to either a unidirectional or a bi-directional port. Conversely, exemplary embodiments also selectively adapt the pad architecture on bi­directional patch panels or ports to connect to legacy unidirectional optoelectronic transceiver modules. This allows the port to function correctly when either a bi­directional or a unidirectional transceiver is connected to it.

Eye safety and interoperability of active cable devices

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.

Network diagnostic systems and methods for using network configuration data

Abstract: A network diagnostic module may use network configuration data in performing network diagnostic methods. The network diagnostic module may use network configuration data to generate baseline network activity data. The network diagnostic module may use network configuration data to identify network components and aggregate network activity data for the components. The network diagnostic module may use network configuration data to identify sets of network components and to access network activity data for the sets. The network diagnostic module may use network activity data to identify sets of network components and to access network configuration data for the sets.
