Abstract: According to an embodiment, an apparatus comprises a fiber-breakout transition configured to break out optical fiber sets from a first end of an optical fiber cable. The fiber-breakout transition comprises a first channel configured to receive an end segment of the optical fiber cable. The fiber-breakout transition further comprises a plurality of second channels. Each of the plurality of second channels is configured to receive and mechanically attach a buildup tube for holding one or more optical fibers. The transition has an interior cavity connecting the first channel to the plurality of second channels. Some of the channels have cross-sections whose diameters increase in a stepped manner with distance away from the interior cavity of the transition.

Abstract: A duplex holder for an optical loopback assembly includes a clip adapted to receive and hold an optical loopback assembly. The clip is mounted in an elongated cover which provides a handle for manipulating the holder. A release latch pivotally mounted to the clip engages release arms on the loopback assembly. An elongated member is pivotally connected to the release latch and extends beyond the rear end of the cover so that it is accessible by a user from the rear of the cover. When the elongated member is translated, it rotates the release latch to move the latch arm of the loopback assembly to a release position so that the loopback assembly can be removed from its associated mating connector by convenient manipulation of the holder.
