摘要： An optical transceiver module characterized by reduced electromagnetic interference (“EMI”) emissions for improved operation is disclosed. The transceiver includes a housing formed by top and bottom housing portions that are joined to define a cavity. A printed circuit board (“PCB”) is positioned within the cavity and includes an edge connector extending from one housing end. The PCB also includes two holes defined near the edge connector and lined with electrically conductive material. Conductive plates located on both the top and bottom housing portions electrically connect with the conductive holes to electrically interconnect the top and bottom housing portions. Two posts on the top housing portion are received into the conductive holes to align the PCB with the housing portions. A chassis ground from one or both of the housing portions extends through the plates and holes to create a “chassis ground fence,” preventing EMI emission from within the transceiver cavity.

摘要： A single-chip integrated circuit, sometimes called a controller, controls operation of a transceiver having a laser transmitter and a photodiode receiver. The controller includes memory for storing information related to the transceiver, and analog to digital conversion circuitry for receiving a plurality of analog signals from the laser transmitter and photodiode receiver, converting the received analog signals into digital values, and storing the digital values in predefined locations within the memory. Comparison logic compares one or more of these digital values with predetermined setpoints, generates flag values based on the comparisons, and stores the flag values in predefined locations within the memory. Control circuitry in the controller shuts off the laser transmitter in response to comparisons of signals with predetermined setpoints that indicate potential eye safety hazards.

摘要： A demultiplexer includes a unitary optically transparent structure that utilizes focusing relay mirrors to relay a multi-wavelength beam of light among a series of wavelength-specific interference filters, with each filter separating out a specific wavelength component from the multi-wavelength beam. The relay mirrors are focusing mirrors, so that the demultiplexer can be operated with a non-collimated light beam in a manner that controls the potentially large angle of divergence of non-collimated light, while taking advantage of the small beam diameter in order to create a demultiplexer with greater miniaturization.

摘要： A zigzag waveguide device is described that includes at least two optical waveguides converged at a vertex to form a waveguide overlap region. Optical loss in the waveguide overlap region is minimized by including a narrow gap of lower refractive index between the overlap region and each waveguide. This technique is also applied to minimize loss in a region where two optical waveguides cross one another. A mirror or optical filter reflectively couples the two waveguides at the vertex. When the coupling is provided by an optical filter, some range of wavelengths is transmitted out of the zigzag waveguide device, rather than reflected. The transmitted light may be collected by an output waveguide which is wider than the waveguides to minimize loss due to divergence. Light exiting the device may be coupled directly to a photodetector with no intervening optical fiber. In addition, the width of an input waveguide of the zigzag waveguide device is tapered to reduce angular spread of the light in the zigzag device.

摘要： 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.

摘要： 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.

摘要： An optical transmission system includes more optical channels than electrical channels. If an optical channel is not functioning, the signals may be diverted to another optical channel since there are more optical channels than electrical channels. Embodiments of the present invention also relate to switches for switching the electrical channels to particular optical channels on either or both of the transmission and reception side. The switches include switching elements and selector elements for routing the electrical signals between the electrical channels and optical channels. In one embodiment, the multiple optical channels are incorporated into a single cable. The single cable may have the electrical interface for a number of electrical channels exposed for mechanical and electrical coupling with an external port, whereas the optical channels may be hidden within the cable coating.

摘要： 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. For instance, devices can use status links to operate above nominal eye safety limits and/or to adjust transmit power to compensate for degradation effects.
