Optical fiber cables having multiple subunit cables

摘要

Micromodule cables include subunit, tether cables having both electrical conductors and optical fibers. The subunits can be stranded within the micromodule cable jacket so that the subunits can be accessed from the micromodule cable at various axial locations along the cable without using excessive force. Each subunit can include two electrical conductors so that more power can be provided to electrical devices connected to the subunit.

1. A micromodule cable, comprising:
a cable jacket; and at least three subunit cables surrounded by the cable jacket and stranded together, wherein each subunit cable has an outside diameter in the range of 4-4.5 mm, each subunit cable comprising:
a subunit jacket having a cavity, wherein the subunit jacket has a jacket wall thickness in the range of 0.3-0.5 mm;a micromodule cable disposed within the subunit jacket, the micromodule cable comprising a plurality of optical fibers surrounded by a micromodule jacket, wherein each micromodule has an outside diameter in the range of 1.3-1.7 mm;a longitudinally extending strength member disposed within the subunit jacket;a first electrical conductor disposed within the jacket; anda second electrical conductor disposed within the jacket,wherein the micromodule cable has an outside diameter in the range of 10.5-11.6 mm.
