Multifiber invisible optical drop cable and methods for routing optical fibers within a multi-dwelling unit
The present disclosure relates to a process by which an optical fiber drop cable is created and routed in a multiple dwelling unit (“MDU”). The optical fiber drop cable is formed with a feeding tool, and the optical fiber drop cable includes a tube having optical fibers enclosed within the tube. The feeding tool creates a slit within the tube through which optical fibers are fed and thereby inserted into the tube along the tube's length. Once the tube exits the feeding tool with the optical fibers enclosed (thereby forming the optical fiber drop cable), the optical fiber drop cable is then routed into an individual dwelling unit of the MDU by a transition assembly including a transition plug and a routing plug that leads an optical fiber from an exterior of the individual dwelling unit to a subscriber termination point in an interior of the individual dwelling unit.
Optical Splitting Apparatus
An optical splitting apparatus includes an enclosure, an even optical splitter and an uneven optical splitter that are disposed in the enclosure. A light inlet and a plurality of light outlets are disposed on the enclosure, and fiber adapters are disposed on the light outlets. The light inlet, the even optical splitter, the uneven optical splitter, and the light outlets are connected, so that optical paths are formed between the light inlet and the light outlets by using the even optical splitter and the uneven optical splitter. The light inlet is connected to at least one of a light input end of the even optical splitter and a light input end of the uneven optical splitter, and the fiber adapter on the light outlet is connected to at least one of a light output end of the even optical splitter and a light output end of the uneven optical splitter.
FIBER OPTIC CONNECTION DEVICE WITH RUGGEDIZED TETHERS
A loop back connector and methods for testing lines in a fiber optic network are disclosed. The loop back connector includes a ferrule having an interface side constructed for optical connection to a multifiber optical cable. The loop back connector also includes first and second optical loop back paths, each having first and second terminal ends positioned at the interface side. The terminal ends of each loop back path are adapted to be aligned to fibers in the multifiber optical cable. The method includes injecting a signal on a first optical path at a first location, looping back the signal at a second location onto a second optical path, and receiving the signal on the second optical path at the first location.

TELECOMMUNICATIONS ENCLOSURE
The present disclosure relates to a telecommunications enclosure haying cable ports and an internal optical tapping or indexing architecture. The cable ports can be defined by hardened fiber optic adapters.
Blocking an optical fiber in a fiber optic cable
It is disclosed a method for coupling an optical fiber to a fiber optic cable, the fiber optic cable comprising a sheath surrounding an optical core comprising a buffer tube, the optical fiber being loosely contained in the buffer tube. The method comprises: cutting the sheath for a predetermined length thereof and exposing a corresponding portion of the optical core extending outward beyond a butt of the cut sheath; cutting the buffer tube of the exposed optical core and exposing a portion of the optical fiber; using a blocking tube to at least partially surround a section of the exposed portion of the optical fiber; and injecting a sealant into the blocking tube to lock the optical fiber within the blocking tube and couple the optical fiber to the fiber optic cable.
Optical wire transition adapter
A transition adapter for routing a first optical cable into a plurality of optical cables of the present disclosure has a main body. In addition, the transition adapter has a first channel within the main body and configured for receiving the first optical cable, a second channel, the first channel open to the second channel, the second channel within the main body and configured for receiving a second optical cable, which is a first portion of the first optical cable, the second channel terminating with a first opening from which the second optical cable extends, and a third channel, the first channel open to the third channel, the third channel within the main body and configured for receiving a third optical cable, which is a second portion of the first optical cable, the third channel terminating with a second opening from which the third optical cable extends.
