摘要： A cable assembly includes a distribution cable, a tether cable, and a network access point (NAP) assembly having a cavity defined therein. The distribution cable includes optical fibers and the tether cable includes an optical fiber. The optical fiber of the tether cable is tightly constrained within the tether cable and portion thereof extends from the tether cable into the cavity of the NAP assembly and is spliced to a portion of one of the optical fibers of the distribution cable extending into the cavity of the NAP assembly from a side of the distribution cable. The splice is positioned in the cavity. Tight constraint of the optical fiber of the tether cable within the tether cable limits transmission of fiber movement to the portion of the optical fiber of the tether cable extending into the cavity of the NAP assembly, thereby protecting the splice.

摘要： A furcation assembly for use with multi-fiber optical fiber cable comprises a housing having a first housing piece and a housing cover. The first housing piece has a furcation block at which a plurality of furcation tubes are terminated and which is configured to receive an end portion of the optical fiber cable such that respective optical fibers thereof may be inserted into a selected furcation tube. The housing cover is received over the first housing piece so as to be locked in a closed position. When the housing cover is in the closed position, the multi-fiber cable is axially retained with respect to the housing.

摘要： A system for stripping an optical fiber includes a source of air, and a means for generating very short bursts of air. The heater (100) includes a heater core that includes a heat generating element and a heat chamber (114) enclosed within the heater core. A spiral-shaped air conduit (116) surrounds the outer surface of the heater core, and communicates with the heat chamber. Upon injection of air into the conduit, heat is transferred to the air from the heat generating element while the air flows through the air conduit and into and out of the chamber through outlet port (201).

摘要： The access tool includes a housing (10) and a block (20) disposed within the housing. The housing has side walls (12) connected by a bottom wall (15) thereby forming a channel (11). The block is disposed within the channel so as to be slidable along the longitudinal axis of the housing, as well as to be movable toward and away from the bottom wall so that the tool may be used on a wide range of optical conductor sizes. The block includes at least one projection (28) which is disposed in at least one groove (13) in the housing so as to connect the block and housing in a simple manner.
To separate a sheath from an optical conductor, the optical conductor is placed within the channel, and then the block is moved toward the bottom wall to squeeze the optical conductor. The optical conductor is then pulled relative to the access tool thereby separating the sheath from the fibers in the optical conductor.

摘要： The present invention provides a method for accessing a fiber from a bundle of fibers (16a-16f) disposed in a sheath (14a-14f). The method comprises several steps which include cutting the sheath circumferentially at a leading position (22) as well as circumferentially at a trailing position (24) to divide the sheath into a leading section (26), a mid-section (28) and a trailing section (30). The sheath is spread along the axis of the sheath between the leading section and the mid-section to create a first access opening(32). A fiber (16a-16d) to be accessed is cut at the first access opening (32). The leading section and mid-section are pushed together to close the first access opening. The sheath is spread along the axis of the sheath between the mid-section (28) and the trailing section (30) to create a second access opening (38) wherein the fiber is pulled from the mid-section of the sheath so that it extends out of the second access opening. The mid-section (28) and trailing section (30) of the sheath are pushed together to close the second access opening while the fiber is permitted to extend out of the trailing cut. Tape may be placed around the cuts to physically join the sections of the sheath and to seal out contaminants.
