A fiber optic drop cable includes an optical fiber, a tight buffer layer on the optical fiber, at least one strength member, and a jacket surrounding the tight buffer layer. The jacket is coupled to the at least one strength member by at least partial embedment of at least one of the strength members in the jacket, which facilitates coupling between the jacket and strength member. The fiber optic drop cable has an average delta attenuation of 0.4 dB or less at a reference wavelength of 1625 nanometers with the fiber optic cable wrapped 2 turns about a 7.5 millimeter diameter mandrel.

Fiber optic cables and assemblies and the performance thereof

Micromodule subunit cables are constructed to allow for ease of identification between optical fibers in differing groups of optical fibers. In one cable, a first group of fibers is located within a buffer tube core while a second group of fibers is located within the cable jacket, but outside of the core. The fibers in the first and second groups can accordingly use the same color coding sequence without requiring additional indicia such as stripes or binding.

Cable with features for distinguishing between fiber groups

A fiber optic cable having optical fibers such as a microstructured bend performance optical fibers disposed within a protective covering. The protective covering is highly flexible and the fiber optic cable has extremely low delta attenuation when aggressively bent compared with the conventional fiber optic cable designs. Other variations of the present invention include a connector attached to the fiber optic cable.

Disclosed are fiber optic ribbons having at least one optical fiber and a protective covering such as a matrix material. The fiber optic ribbons include an attachment portion for providing the craft an installation option for securing the same. Specifically, the fiber optic ribbon has a first portion that has at least one optical fiber and an attachment portion. The attachment portion generally extends away from the first portion, thereby providing a portion of the fiber optic structure suitable for receiving a fastener therethrough without damaging the at least one optical fiber or causing undue levels of optical attenuation. Moreover, the fiber optic ribbon may be used by itself if a rugged construction is provided or can further include cable components such as a cable jacket. The fiber optic structures may also have a bulbous first portion for indicating the location of the optical fiber to the craft.

Fiber optic ribbons having an attachment portion

A tube assembly of the present invention has at least one subunit with at least one dry insert generally surrounding the subunit which may be disposed within a tube, thereby forming a tube assembly. The subunit includes a fiber optic ribbon and a sheath, wherein the sheath is tight-buffered about the fiber optic ribbon, thereby inhibiting buckling of the ribbon during temperature variations. Additionally, the tube assembly can be a portion of a fiber optic cable having a sheath that may include a plurality of strength members and a cable jacket. In other embodiments, the subunits and dry insert are disposed within a cavity, thereby forming a tubeless cable. Additionally, subunits may include a marking indicia for denoting the security level.

Dry fiber optic assemblies and cables

Disclosed is a fiber optic drop cable including at least one optical waveguide, at least one roving, and a cable jacket. In one embodiment, the at least one roving includes a resin matrix having a water-based acrylic composition that includes an ethylene-acrylic acid and a water-swellable component. The resin matrix has a percent by weight of about 10 percent or less of the flexible roving so that the at least of one roving is at least partially bonded with the cable jacket, thereby inhibiting buckling of the cable jacket. In another embodiment, a plurality of rovings are arranged in clusters in the cable for influencing the bonding between the rovings and cable jacket. Also, disclosed is a protective casing for protecting and routing optical fibers along with preconnectorized cable assemblies.

Protective casings for optical fibers

A communication cable including at least one communication element having a ripcord for ripping at least one cable component for facilitating access to the communication cable. In one embodiment, the ripcord is formed from a plurality of plies twisted together in a first direction, each of the plurality of plies being formed from a plurality of strands twisted together in a second direction. In another embodiment, the ripcord is formed from at least two different filament materials such as polyester and polyethylene.
