Reverse power sharing
A power distributor for a communications system for controlling delivery of electrical power drawn over a plurality of electrical communications connections allocated to respective customer premises equipment, to provide electrical power to network components within a network is arranged to control collection of electrical power to be drawn from each connection in accordance with power requirements of services operated by or for its respective customer premises equipment, independent of the identities of the electrical connections used to deliver those services. In particular when electrical connections are not being used by their respective customers they may instead be used by a beam-forming system to support improved service to a customer associated with a different connection, and the additional electrical power to power the beam-former is drawn from the connection associated with the customer receiving the enhanced service.
Isolator integrated circuits with package structure cavity and fabrication methods
In described examples, an integrated circuit includes a leadframe structure, which includes electrical conductors.

Remotely pumped free-space optical (FSO) communication terminals
This invention pertains to the field of free-space optical (FSO) communications, and specifically to the realization of functional FSO optical transceiver terminals located at remote electrically unpowered locations within a communications network. A remote unpowered FSO terminal located at a far-end location receives necessary optical power from a powered base station location (near-end) required for all optical amplification functions necessary for NRZ or RZ format signals within the spectral range of 900 nm to 1480 nm as well as an Ultra Short Pulsed Laser (USPL) centered at 1560 nm at the far-end location. A transmitting node identified as the near-end transmits an optical signal identified as a pump signal to a remote location classified as the far-end node over a free space medium, such as the atmosphere, where the far-end node location does not have available electrical power for operation of electro-optic components required for transmission and retransmission functions.
Compact optic-connecting device
The present disclosure provides a compact-optic-connecting device for mounting on a motherboard of a computer, which includes an optic-receiving unit, an optic-launching unit, two flexible-circuit plates, a circuit board and a connecting interface. The optic-receiving unit and the optic-launching unit are connected to the bottom surface of the circuit board respectively via flexible-circuit plates. The connecting interface is connected to the bottom surface of the circuit board, and also connected to an external motherboard via the connecting interface. By virtue of such structure, the compact optic-connecting device can have a small length and size, and meanwhile to maintain a safety distance between the connecting interface and the optic-receiving unit, or the connecting interface and optic-launching unit, to prevent faulty conduction therebetween.
THERMALLY INTERFACING CHIP ON GLASS ASSEMBLY
In one example embodiment, an optoelectronic assembly includes an electronic substrate, a transparent component coupled on a first side of the electronic substrate, and a first component coupled to a second side of the electronic substrate opposite the first side. The electronic substrate, the transparent component, and the first component may define a hermetically sealed enclosure. A laser array or a receiver array may be mechanically coupled to the transparent component inside of the enclosure and oriented to transmit or receive optical signals through the transparent component. The laser array or the receiver array may be electrically coupled to the electronic substrate. A second component may be positioned between the first component and the transparent component in the hermetically sealed enclosure with a thermal interface material forming a first interface between the second component and the transparent component.
OPTICAL LINK MANAGEMENT
The present disclosure provides optical link management in a marine seismic environment. A first device can transmit, to a second device, a first optical transmission at a first output level. The first optical transmission can include a first packet corresponding to a network protocol. The first device can determine that the second device failed to receive the first packet via the first optical transmission. The first device can transmit, responsive to failure of the first optical transmission, a second optical transmission at a second output level different than the first output level. The second optical transmission can include a second packet corresponding to the network protocol. The first device can identify that the second packet was successfully received by the second link manager agent. The first device can establish, responsive to the identification that the second packet was successfully received, the second output level as a transmission output level for the first device.
OPTICAL MEMORY GATES
In example implementations, an optical gate is provided. The optical gate receives at least one optical signal via a waveguide of an optical memory gate.
