Publication number: 20180039037Abstract: A closure includes a cover and seal block. A feeder cable pathway and rear cover is provided for separation of feeder cables from drop cables. The organizer in the closure includes an end cap and rear cable storage. Cable fixation clips, linear or bendable, can be used individually or daisy chained together. Cable fixation chambers are positioned on top of the gel block housing. The organizer is a click together organizer. Dual heights on cable guides on sides of the groove plate facilitate cable installation. Tray supports with rounded ends prevent looseness of the tray mounts.Type: ApplicationFiled: October 16, 2017Publication date: February 8, 2018Inventors: Mohamed AZNAG, Emilie DE GROE, Eric Marcel M.

Publication number: 20180039040Abstract: Novel tools and techniques for direct cable expansion are provided. A system includes a pump, a probe, and a coupler. The pump is coupled to a reservoir holding a fluid. The probe is in fluid communication with the pump, and is configured to introduce the fluid into a cable such that a channel is created, by the fluid, between an outer sheath of the cable and a core of the cable. The coupler is configured to attach to a cable, receive the probe, and position the probe at an interface between the outer sheath and an inner material of the cable adjacent to the outer sheath.Type: ApplicationFiled: August 4, 2017Publication date: February 8, 2018Inventors: Michael L. Elford, Pete A. Kawamoto, Diana L. Unser
