摘要:
A network interface device (NID) for a fiber optic communications network is provided for housing optical, electrical and/or coaxial connections and active and/or passive components. The NID includes a base and a movable panel defining a connections area and a components area. In one embodiment, a first base defines a first compartment for housing the panel and a second base defining a second compartment for storing drop cable slack, the first base being movably attached to the second base to provide access to the drop cable slack without disturbing the connections. In another embodiment, the panel defines a first compartment for optical and electrical connections and a second compartment for active and passive components, the second compartment being accessible to only the service provider. In another embodiment, the panel is removable and interchangeable to permit the service provider to upgrade the services or to expand services provided to a subscriber.

A slack storage receptacle for storing an excess length of a pre-connectorized fiber optic drop cable extending between an optical connection terminal and a network interface device (NID) includes a housing and a storage means disposed within the housing for receiving the drop cable such that the drop cable slack is stored external to the NID. The slack storage receptacle may be secured to an exterior wall of a subscriber premises and the NID mounted thereon. Alternatively, the slack storage receptacle may be positioned around and formed to the NID. Alternatively, the slack storage receptacle may be buried in the ground adjacent the NID. The drop cable slack may be wound onto the storage means after deployment. Alternatively, the slack storage receptacle may be pre-assembled, shipped to the subscriber premises, and the drop cable unwound from the storage means with the drop cable slack remaining wound on the storage means.

A low cost universal network interface device capable of accommodating various terminating devices. The network interface device generally including a base defining an interior cavity, and being further defined by a provider portion and a subscriber portion. The network interface device further including a protective outer cover having an integrated override feature operable for permitting access to the provider portion and the subscriber portion of the base in one step. The network interface device also includes an improved terminating device having a locking feature having a locking slide and a movable latch for preventing unauthorized access to the interior of the terminating device. The network interface device further comprises a sealing grommet having a wave like shape for sealingly enveloping provider or subscriber lines that are routed into the base, thereby preventing outside contaminants from entering.

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 Network Interface Device (NID) component includes a base configured to receive, in a cavity, both a subscriber wire contact and a provider wire contact. The component also includes a cover in movable attachment to the base, the cover including a bridge contact, wherein the bridge contact makes electrical connection between the subscriber wire contact and the provider wire contact when the cover is in a closed position and breaks the electrical connection when in an open position.

Embodiments of the present invention relate to the fabrication of a buried bi-layer insulator of silicon oxide and silicon nitride in a microelectronic substrate, and to the buried silicon oxide/silicon nitride bi-layer insulator itself. The buried silicon oxide/silicon nitride bi-layer insulator may be formed by implanting oxygen ions and nitrogen ions into the silicon-containing microelectronic substrate and then annealing the silicon-containing microelectronic substrate to form silicon oxide and silicon nitride layers therein.

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.

An optical termination pedestal defines an interior cavity for interconnecting an optical fiber of a distribution cable and an optical fiber of a drop cable. The pedestal includes a base, a housing positioned over the base, and a plate secured to the housing or the base. The plate separates the interior cavity into a first compartment and a second compartment and has at least one cable port for routing the distribution cable into the first compartment. At least one connector port may be provided on the plate for receiving a connectorized optical fiber of the distribution cable from the first compartment and a pre-connectorized drop cable from the second compartment. The plate is provided with an O-ring to seal the first compartment relative to the second compartment. As a result, a sealed splice closure is created within the interior cavity without the need for a separate enclosure.
