There are provided fiber optic local convergence points ('LCPs') adapted for use with multiple dwelling units ('MDUs') that facilitate relatively easy installation and/or optical connectivity to a relatively large number of subscribers. The LCP includes a housing mounted to a surface, such as a wall, and a cable assembly with a connector end to be optically connected to a distribution cable and a splitter end to be located within the housing. The splitter end includes at least one splitter and a plurality of subscriber receptacles to which subscriber cables may be optically connected. The splitter end of the cable assembly of the LCP may also include a splice tray assembly and/or a fiber optic routing guide. Furthermore, a fiber distribution terminal (&#x201c;FDT&#x201d;) may be provided along the subscriber cable to facilitate installation of the fiber optic network within the MDU.

An optical fiber distribution enclosure includes a housing defining an interior, a first fiber distribution area disposed within an upper portion of the interior, a second fiber distribution area disposed within a lower portion of the interior and a signal splitting area disposed between the fiber distribution areas. A splitter module secured within the signal splitting area has a connectorized splitter input optical fiber and connectorized splitter output optical fibers. A fiber parking area is movably disposed within the lower portion adjacent the second fiber distribution area for temporarily storing splitter output optical fibers that are not routed to the fiber distribution areas. An input fiber distribution area disposed within the interior interconnects an optical fiber of a feeder cable with the splitter input optical fiber. The splitter output optical fibers are eventually routed to a fiber distribution area and interconnected with a corresponding optical fiber of a distribution cable.

An optical connection closure has at least one connector port located within an external wall of the closure for receiving a connectorized optical fiber of a distribution cable on the inside of the closure and a pre-connectorized fiber optic drop cable on the outside of the closure. The closure includes a base, a cover affixed to the base and movable between a closed position and an opened position, and an end wall that defines at least a portion of at least one cable opening for receiving the distribution cable in a butt-type or a through-type closure configuration. The base and the cover define an interior cavity that optionally contains a splice tray for interconnecting the optical fiber of the distribution cable with a pigtail to create the connectorized optical fiber. The connector port may be located within an end wall, a bottom wall or a top wall of the closure.

A compact optical splitter module is disclosed. One type of compact optical splitter module is a planar attenuated splitter module that includes a branching waveguide network having j&#x2267;1 50:50 splitters that form up to n&#x2266;2output waveguides having associated n output ports, wherein only m&#x3c;n output ports are suitable for transmitting light to the at least one external output device. This provides a 1&#xd7;m splitter module wherein each output port has the attenuation of a 1&#xd7;n splitter module, thereby obviating the need for external attenuation. Another type of compact optical splitter module is a direct-connect splitter module that eliminates the need for an optical fiber array when coupling to external optical fibers. Another type of compact optical splitter module is a microsplitter module that serves as device and module at the same time and that eliminates the differentiation between device and module. The integration of device and module also makes manufacturing the microsplitter module cost-effect. Embodiments of microsplitter modules that account for differences in the coefficient of thermal expansion of the materials making up the microsplitter are also disclosed.

There is provided fiber drop terminals ('FDTs') and related equipment for providing selective connections between optical fibers of distribution cables and optical fibers of drop cables, such as in multiple dwelling units. The FDTs require relatively little area and/or volume while providing convenient connectivity for a relatively large number of optical connections. The FDTs include adapters for optically connecting the connectors, and the adapters of some FDTs are adapted to rotate, move, or otherwise be removed to provide convenient access for technicians. Some FDTs and the related equipment are adapted for use with microstructured optical fiber having preferred bend characteristics.

An installation closure having fiber management apparatus includes an outer shell and at least one cable centralizer disposed within the outer shell at a factory-assembled access location on a fiber optic distribution cable. The cable centralizer has a central channel for retaining the distribution cable and at least one routing slot for routing an optical fiber preterminated from the distribution cable at the access location. At least a portion of the outer shell is removed following deployment of the distribution cable and replaced with a conventional closure. An optical connector may be mounted upon the end of the preterminated optical fiber and the installation closure may further include an end centralizer having a central channel for retaining the distribution cable and at least one connector slot for retaining the connector. The replacement closure includes at least one connector port for receiving the connector from the inside of the installation closure.

A fiber optic cable has a plug assembly that may be positioned and secured at any desired location along the length of the cable to engage a receptacle disposed within a connector port provided in a wall of a connection terminal. The plug assembly includes a shroud, a coupling nut, a heat shrink tube for sealing the cable and a boot for providing bending strain relief. At least a portion of the cable passes through the connector port for interconnection with optical fibers of a distribution cable or optical equipment. A method for routing a fiber optic cable into a connection terminal includes using a connector port provided in a wall of the terminal, determining a desired length of the cable, positioning and securing a plug assembly at a desired location along the length of the cable, and mating the plug assembly with a receptacle disposed within the connector port.

A ground retention apparatus is provided for deterring the theft of services from an outdoor pedestal. The ground retention apparatus includes a ground stake having a first end attached to the pedestal and a second end opposite the first end for engaging the ground beneath the pedestal. The ground retention apparatus further includes a stop plate secured to the ground stake medially between the first end and the second end. The stop plate defines a hinge line separating a lower portion that is stationary and an upper portion that is movable relative to the lower portion between a first position wherein the upper portion is generally parallel to the lower portion and a second position wherein the upper portion is angled relative to the lower portion. The stop plate prevents the ground stake from being removed from the ground, thereby deterring unauthorized access to the equipment inside the pedestal.

A protector panel for telecommunication wires has a plurality of rows of sockets. Each of the sockets has two pairs of receptacles for receiving pins of a plug-in excess voltage protector module. Rows of pins protrude from the back of the panel, each of the pins registering with one of the receptacles so as to provide two pairs of pins for each socket pattern. A pair of outside-plant wires extends from one of the pairs of pins of each socket pattern. Similarly, a pair of customer premises wires extends from the other of the pairs of each socket pattern. The pairs of wires are twisted substantially along their entire length. The amount of twist of at least some of the pairs of the outside-plant wires within each row differs from the amount of twist of at least some of the other pairs of outside-plant wires. Similarly, the amount of twist of the customer premises wires also differs from others in the same row. Further, the twisted pairs that are adjacent each other, but in different rows, will have different pitches. The differences in the amounts of twist of the pairs of wires enable the protector panel to handle high frequency transmissions while minimizing cross talk.

A protector panel having a plurality of parallel rows of socket groups that include a plurality of receptacles for receiving pins of plug-in excess voltage modules. The socket groups on adjacent rows are offset such that they are oriented relative to one another such that each incoming tip receptacle of each of the socket groups in one row is more closely spaced to one of the other receptacles rather than the incoming ring receptacle of the adjacent row. The socket groups within one row may also be rotated relative to socket groups in an adjacent row. On the back of the protector panel, a plurality of pins are positioned to communicate with the socket groups. Wire pairs lead to and wrap around each of the pins. The wires are twisted about one another to a location near the pins at which point a first wire and a second wire of the wire pairs are separated to attach to their respective pins, wherein the number of twists per liner increment varies from one pair to another wire pair in close proximity.
