Carbon fiber based tubing encapsulated cable
Tubing encapsulated cable consists of one or more electrical conductors and possibly one or more fiber optic cables sheathed in a corrosion resistant metallic alloy. However, pumping during the installation of tubing encapsulated cable is required to overcome the capstan effect of the tubing encapsulate cable inside the coil tubing as the tubing encapsulated cable travels through the coiled up wraps of coil tubing. In an embodiment of the invention the tubing encapsulated cable consists of one or more electrical conductors and possibly one or more fiber optic cables sheathed in a fiber reinforced composite sheath. Because there is little drag between the fiber encapsulated cable and the coil tubing, conventional pumping operations used to install braided wireline into coil tubing may not be required when installing fiber encapsulated cable into coil tubing. Additionally, the smooth outside surface and relatively small diameter of the fiber encapsulated cable are desirable attributes for well intervention work because the smooth surface is more resistant to chemical attack than braided wire while the smooth surface and relatively small diameter provide little viscous drag while fluids are pumped through the coil tubing in the course of intervention operations.

USB and Thunderbolt Optical Signal Transceiver
Systems and methods to implement a USB and Thunderbolt optical signal transceiver are described. One method includes detecting presence of a USB sideband signal received over an optical communication channel and associated with a USB communication request. Responsive to the detecting, the method may determine that the USB communication request corresponds to a USB communication mode and perform a sideband negotiation. The USB communication mode may be enabled. A specified number of channels associated with the USB communication request may be determined. USB communication may be performed using the specified number of channels over the optical communication channel in the USB communication mode.
