摘要： Disclosed are fiber optic assemblies having at least one optical fiber and a water-swellable powder within a tube and/or cavity and methods for making the same. Fiber optic assemblies of the present invention use relatively low-levels of water-swellable powder while still effectively blocking the migration of tap water and/or saline solutions of 3% by weight along the tube and/or cavity. Furthermore, cleaning of the optical fibers is not necessary before connectorization like with conventional fiber optic cables that use a gel or grease. Generally speaking, at least some of the water-swellable powder is transferred to the inside surface of the tube, cavity, optical fiber or the like; rather, than being a loose powder that is able to migrate within the tube or cavity. Moreover, the existence of water-swellable powder within the fiber optic assembly or cable is nearly transparent to the craft since relatively low-levels are used.

摘要： A tight buffered optical fiber (10) and methods of manufacturing the same include an optical fiber (1) and a tight buffer layer (15). The tight buffer layer has a predetermined wall thickness (t) generally surrounding the optical fiber and at least one preferential tear portion generally formed along a longitudinal axis of the tight buffer layer. In one embodiment, the tight buffered optical fiber has a delta attenuation of about 0.300 dB/km or less at a temperature of about -40 °C at a reference wavelength of about 1550 nm, thereby making the tight buffered optical fiber suitable for outdoor environments. Other embodiments can include a buffer layer surrounding one or more optical fiber ribbons. In other embodiments, the buffer layer can be formed from a material having an elongation to break ratio of about 500% or less.

摘要： Fiber optic bundles include helically stranded subunit cables. The assemblies have small cross sections and low bend radii while maintaining acceptable attenuation losses. Binders can be omitted to improve ease of processing and installation. Helically stranding of the subunit cables allows ease of access to the individual cables during installation.

摘要： Fiber optic cables and assemblies for routing optical networks closer to the subscriber. The fiber optic cables have a small-cross section yet robust design that is versatile by allowing use in aerial application with a pressure clamp along with use in buried and/or duct applications. Additionally, the fiber optic cables and assemblies have a relatively large slack storage capacity for excess length. Assemblies include hardened connectors such as plugs and/or receptacles suitable for outdoor plant applications attached to one or more ends of the fiber optic cables for plug and play connectivity.

摘要： Methods for manufacturing cables and cables assemblies include providing particulate matter within a tube extruded about optical fiber. The particles may be accelerated so that as they strike the tube they mechanically attach to the tube.
