Abstract: A cable, which extends in a longitudinal direction, has a cable core and a cable jacket. The cable jacket is extruded around the cable core. The cable is distinguished by the fact that the cable jacket has a plurality of chambers and, overall, is designed, in particular, in the manner of a hollow profile, and by the fact that a functional material different from the material of the cable jacket is introduced within at least one of the chambers. The functional material is preferably a flame proofing agent, but numerous other materials and, in general, functional elements are also conceivable. We further describe a method for producing the cable.

Abstract: An optical interface includes a rack mountable enclosure that includes multiple slots for retaining multiple insertable fiber optic (FO) modules. The FO modules include a first set of interconnection ports that connect to remote radio units (RRUs), a second set of interconnection ports that connect to a baseband unit (BBU), and a third set of monitoring ports that connect to monitoring/text equipment. The FO modules contain fiber splitters that split off uplink/receive and downlink/transmit signals carried on optical fibers to the third set of monitoring ports. The FO modules may insert in different orientations and directions into different rack mountable enclosure configurations for higher density and more configurable connectivity. A splitter holder is located within the FO module and provides improved optical fiber routing for more integrated module port interconnectivity.

Abstract: An integrated circuit that reduces back reflection of an optical signal is described. This integrated circuit may convey an optical signal in an optical waveguide defined in a layer in the integrated circuit. The integrated circuit may split the optical signal into portions of the optical signal using an optical splitter, and may convey the portions of the optical signal in at least two arms of the optical waveguide. Then, the integrated circuit may establish a predefined phase offset between the portions of the optical signal using at least a phase-offset device in one of the two arms. Furthermore, the integrated circuit may optically couple the portions of the optical signal at optical coupling interfaces at ends of the two arms. Note that the predefined phase offset may reduce the back reflection of the optical signal at the optical splitter to less than a threshold value.
