Problems solved by technology

However, as a result of the very strong and durable nature of such cables, such cables are often very rigid, inflexible and difficult to handle
In addition, such cables are expensive to manufacture

Embodiment Construction

[0018] figure 1 A fiber optic cable 10 is shown in accordance with the principles of the present disclosure. The fiber optic cable 10 includes at least one optical fiber 12 housed in a buffer tube 14 . An outer sheath 16 surrounds the buffer tube 14 . A strength member 18 is embedded in the outer jacket 16 to provide axial reinforcement to the fiber optic cable 10 .

[0019] still refer to figure 1 , the outer sheath 16 has a non-circular outer contour. For example, if figure 1 As shown, the outer profile of the outer sheath 16 has an oblong or rectangular shape when viewed in cross-section. The outer sheath 16 is longer along the major axis 20 than along the minor axis 21 . The major and minor axes 20 , 21 are perpendicular to each other and intersect at the center 27 of the outer sheath 16 .

[0020] still refer to figure 1 , the outer sheath 16 defines a single fiber channel 23 in which the buffer tube 14 is disposed. Such as figure 1 As shown in the example, the ...

Abstract

The present disclosure relates to a fiber optic cable including an outer jacket having an elongated transverse cross-sectional profile defining a major axis and a minor axis. The transverse cross-sectional profile has a maximum width that extends along the major axis and a maximum thickness that extends along the minor axis. The maximum width of the transverse cross-sectional profile is longer than the maximum thickness of the transverse cross-sectional profile. The outer jacket also defines first and second separate passages that extend through the outer jacket along a lengthwise axis of the outer jacket. The second passage has a transverse cross-sectional profile that is elongated in an orientation extending along the major axis of the outer jacket. The fiber optic cable also includes a plurality of optical fibers positioned within the first passage a tensile strength member positioned within the second passage. The tensile strength member has a highly flexible construction and a transverse cross-sectional profile that is elongated in the orientation extending along the major axis.

Description

[0001] This application is an international patent application filed on October 28, 2009 in the name of ADC Telecom, Inc., a domestic enterprise in the United States. ADC Telecom Inc. is designated as applicant in all countries except the United States, Wayne M. Kachmar, US citizen, as an applicant designating the US only, and claiming priority to US Provisional Patent Application Serial No. 61 / 109,041, filed October 28, 2008. Background technique [0002] A fiber optic cable typically includes: (1) an optical fiber; (2) a buffer layer surrounding the optical fiber; (3) a plurality of strength members loosely surrounding the buffer layer; and (4) an outer jacket. The function of the optical fiber is to carry the light signal. A typical optical fiber includes a core surrounded by a cladding protected by a coating. The function of the buffer layer is to surround and protect the coated optical fiber. The strength member adds mechanical reinforcement to the fiber optic cable to ...
