  • COMPACT ARMORED INTERMITTENTLY BONDED RIBBON CABLES
    Publication number: 20250093605
    Abstract: The present disclosure provides an armored cable (100, 200) including a plurality of optical fibers (106) arranged in a plurality of IBRs, which can be bundled or unbundled. The IBRs are enclosed by a first layer of thin polymer sheath (102, 202). The first layer (102, 202) is further enclosed in a second layer (108, 208), which is placed within an armor layer (110, 210). An outer cable jacket (112, 212) surrounds the armor layer (110, 210), which optionally comprises at least a reinforcing member (114, 214).

  • OPTICAL FIBER RIBBON WITH SELECTIVE SUPERABSORBENT COATING
    Publication number: 20250004228
    Abstract: The present disclosure provides an optical fiber ribbon (10) comprising a plurality of optical fibers (11) with coating of superabsorbent material (C). The coating (C) is applied selectively on bonded regions (13) or unbonded regions (14) of the ribbon (10). The ribbon (10) provides for reduced diameter, higher packing density, and reduced micro-bending losses. Optical fiber cable (20) comprising optical fiber ribbon (10) is also provided in the present disclosure.
