An anchoring assembly for securing a cable having both an optical fiber and an electrical conductor in order to provide a conductive pathway to a downhole tool. The anchoring assembly has a head and tail each having a throughbore with anchor receiving portions. An anchor with a deformable portion maybe inserted into the anchor receiving portions and the head and tail drawn together about the anchor. The anchor receiving portions have a narrowing diameter, which, upon abutment with the anchor causes the deformable portion of the anchor to deflect inward and secure a cable inserted therein. A conductive body is provided in the head or tail for coupling with the cable and providing a conductive pathway to a downhole tool.

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.

A cable contains a core including a transmissive element and a coating layer made of a coating material. The coating material contains, with respect to the total weight of polymeric materials present in the composition, (i) 70% to 95% by weight of a recycled linear low density polyethylene (r-LLDPE); and (ii) 5 to 30% by weight of an ethylene-vinyl acetate copolymer (EVA). The coating layer shows mechanical properties comparable to those of a virgin polymer composition and better, both before and after ageing, than recycled polymer-based compositions containing recycled LLDPE but free from EVA. The EVA may be added to the r-LLDPE or, alternatively, be already contained in the r-LLDPE as a result of previous LLDPE use. The cable may further contain a skin layer placed around and in direct contact with the coating layer based on r-LLDPE.

Disclosed are approaches for forming a semiconductor device. In some embodiments, a method may include providing a patterned hardmask over a substrate, and providing, from an ion source, a plasma treatment to a first section of the patterned hardmask, wherein a second section of the patterned hardmask does not receive the plasma treatment. The method may further include etching the substrate to form a plurality of fins in the substrate, wherein the first section of the patterned hardmask is etched faster than the second section of the patterned hardmask.

In order to suppress landing construction, these landing cables, which are installed offshore from a cable landing position, are each provided with: an initially used optical fiber that is used from the initial start of communication by the landing cable; and a preliminary optical fiber which is a preliminary optical fiber in addition to the initially used power feed line used from the initial start, wherein the preliminary optical fiber is connected from a cable landing position side terminal point to boundary points between the cable landing position side terminal point and a cable interval that does not include the preliminary optical fiber, and the terminal point of the preliminary optical fiber, which is the terminal point of the preliminary optical fiber in the boundary points, is held in a state of being usable in the future.
