摘要： 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.

摘要： The present invention relates to an optical fiber having a structure to enable both prevention of resin coating combustion due to leaked light, and low-loss light transmission. The optical fiber comprises a core region, and a cladding region. The cladding region is constituted by an optical cladding which affects the transmission characteristics of light propagating in the core region, and a physical cladding which does not affect the transmission characteristics of light propagating in the core region. Particularly, a leakage reduction portion is provided in the physical cladding so as to surround an outer periphery of the core region through the optical cladding. The leakage reduction portion functions to suppress propagation of the leaked light propagating from the core region toward outside the cladding region.

摘要： Various types of holey fiber provide optical propagation. In various embodiments, for example, a large core holey fiber comprises a cladding region formed by large holes arranged in few layers. The number of layers or rows of holes about the large core can be used to coarse tune the leakage losses of the fundamental and higher modes of a signal, thereby allowing the non-fundamental modes to be substantially eliminated by leakage over a given length of fiber. Fine tuning of leakage losses can be performed by adjusting the hole dimension and/or the hole spacing to yield a desired operation with a desired leakage loss of the fundamental mode. Resulting holely fibers have a large hole dimension and spacing, and thus a large core, when compared to traditional fibers and conventional fibers that propagate a single mode. Other loss mechanisms, such as bend loss and modal spacing can be utilized for selected modes of operation of holey fibers. Other embodiments are also provided.

Acoustic sensing of a wellbore, pipeline, or other conduit/tube based on DAS may have increased acoustic sensitivity through fiber optic cable design and/or increasing the Rayleigh backscatter property of a fiber's optical core. Some embodiments may utilize a resonant sensor mechanism with a high Q coupled to the DAS device for increased acoustic sensitivity.
