An integrated circuit includes a substrate having a main surface and an electrical transmission line extending along the main surface. The electrical transmission line includes a metallic travelling wave electrode (TWE) having a lengthwise sequence of spaced apart openings absent of the metallic material. The substrate has cavities under at least some of the openings. In an example implementation, the TWE is a middle electrode of an electrical transmission line driving an MZM, and the cavities in the substrate extend under side electrodes of the transmission line.

In a Precision Time Protocol (PTP) clock-distribution system, each transparent clock (TC) along a link between a time transmitter (TT) and a time receiver (TR) is able to increment a stepsRemoved field of a PTP message that traverses the TC, such that, at the receiving node of the PTP message (e.g., the TR for certain sync, follow-up, and delay-response messages and the TT for certain delay-request messages), the stepsRemoved field indicates the number of transparent clocks (TC) along the link between the TT and the TR. The information may be used to prioritize certain links over others.

Disclosed is a method comprising determining in accordance with a modulation scheme a candidate set of soft bit blocks representing at least part of the data, wherein an application of each geometric transformation operation of a set of geometric transformation operations to a corresponding subset of the set of constellation points or to the set of constellation points, preserves the shape of the modulation constellation but results in representing different data, for each geometric transformation operation of the set of geometric transformation operations, modifying according to the geometric transformation operation corresponding soft bit blocks of the candidate set of soft bit blocks resulting in another candidate set of soft bit blocks, and selecting from the candidate sets of soft bit blocks the candidate set of soft bit blocks that likely represents the at least part of the data.
