Dark Fiber Loop definition

Dark Fiber Loop is fiber within an existing fiber optic cable that has not yet been activated through optronics to render it capable of carrying communications services.

Dark Fiber Loop consists of continuous fiber optic strand(s) in a Verizon fiber optic cable between the fiber distribution frame, or its functional equivalent, located within a Verizon Wire Center, and Verizon’s main termination point, such as the fiber patch panel located within a Customer premise, and that has not been activated through connection to the electronics that “light” it, and thereby render it capable of carrying Telecommunications Services. In addition to the other terms and conditions of this Agreement, the following terms and conditions also shall apply to Dark Fiber Loops:

In addition to the other terms and conditions of this Agreement, the following terms and conditions also shall apply to Dark Fiber Loops: (a) Verizon shall be required to provide a Dark Fiber Loop only where (a) one end of the Dark Fiber Loop terminates at LightWave's collocation arrangement and (b) the other end terminates at the Customer premise. A CLEC demarcation point shall be established either in the main telco room of a building where a Customer is located or, if the building does not have a main telco room, then at a location to be determined by Verizon. Verizon shall connect a Dark Fiber Loop to the demarcation point by installing a fiber jumper. (b) LightWave may access a Dark Fiber Loop only at a pre-existing hard termination point of such Dark Fiber Loop, and LightWave may not access a Dark Fiber Loop at any other point, including, but not limited to, a splice point. Verizon will not introduce additional splice points or open existing splice points to accommodate a CLEC’s request. Unused fibers located in a cable vault or a controlled environment vault, manhole or other location outside the Verizon Wire Center, and not terminated to a fiber patch, are not available to LightWave.

Dark Fiber Loop means two fiber optic strands (a pair) located within a Verizon fiber optic cable sheath between an accessible terminal (such as the fiber distribution frame, or its functional equivalent) located in a Verizon Wire Center end office and Verizon's accessible terminal located in Verizon's main termination point at the premises of a Customer (such as a fiber patch panel), but that are not connected to any equipment used or that can be used to transmit and receive telecommunications traffic. A “Dark Fiber IOF” means two fiber optic strands (a pair) that are located within a fiber optic cable sheath between either (a) accessible terminals in two or more Verizon central offices or (b) an accessible terminal in a Verizon central office and an accessible terminal in an AT&T central office, but, in either case, that are not connected to any equipment used or that can be used to transmit and receive telecommunications traffic. Verizon shall not be required to perform splicing to provide fiber continuity between two locations. When AT&T submits an order for a Dark Fiber Loop or a Dark Fiber IOF, such fiber may not conform to industry transmission standards, either the ones in effect when Verizon installed such fiber or the ones in effect at the time of such order. Notwithstanding anything else set forth in this Agreement, Verizon shall provide AT&T with access to Dark Fiber Loops and Dark Fiber IOF in accordance with, but only to the extent required by, Applicable Law.

Dark Fiber Loop means two continuous fiber optic strands (a pair) located within a BA fiber optic cable sheath between a BA end office and the premises of a Customer but that are not connected to any equipment used or that can be used to transmit and receive telecommunications traffic. A “Dark Fiber IOF” means two continuous fiber optic strands (a pair) that are located within a fiber optic cable sheath between either (a) two BA central offices or (b) a BA central office and a NEXTLINK central office, but, in either case, that are not connected to any equipment used or that can be used to transmit and receive telecommunications traffic. A strand shall not be deemed to be continuous if a new splice or other means of connection must be installed in order to provide fiber continuity between two locations. When NEXTLINK submits an order for a Dark Fiber Loop or a Dark Fiber IOF, such fiber may not conform to industry transmission standards, either the ones in effect when BA installed such fiber or the ones in effect at the time of such order. Notwithstanding anything else set forth in this Amendment or in the Interconnection Agreement, BA shall provide NEXTLINK with access to Dark Fiber Loops and Dark Fiber IOF in accordance with, but only to the extent required by, Applicable Law.

  • Dark Fiber shall have the meaning set forth in Section 9.7.1.

  • Digital Cross Connect System or "DCS" is a function which provides automated Cross Connection of Digital Signal Level 0 (DS0) or higher transmission bit rate digital channels within physical interface facilities. Types of DCS include but are not limited to DCS 1/0s, DCS 3/1s, and DCS 3/3s, where the nomenclature 1/0 denotes interfaces typically at the DS1 rate or greater with Cross Connection typically at the DS0 rate. This same nomenclature, at the appropriate rate substitution, extends to the other types of DCS specifically cited as 3/1 and 3/3. Types of DCS that cross connect Synchronous Transport Signal level 1 (STS-1 s) or other Synchronous Optical Network (SONET) signals (e.g., STS-3) are also DCS, although not denoted by this same type of nomenclature. DCS may provide the functionality of more than one of the aforementioned DCS types (e.g., DCS 3/3/1 which combines functionality of DCS 3/3 and DCS 3/1). For such DCS, the requirements will be, at least, the aggregation of requirements on the "component" DCS. In locations where automated Cross Connection capability does not exist, DCS will be defined as the combination of the functionality provided by a Digital Signal Cross Connect (DSX) or Light Guide Cross Connect (LGX) patch panels and D4 channel banks or other DS0 and above multiplexing equipment used to provide the function of a manual Cross Connection. Interconnection is between a DSX or LGX to a Switch, another Cross Connection, or other service platform device.

  • Universal Digital Loop Carrier (UDLC) means the DLC system that has a CO terminal channel bank that is connected to the CO switches on the analog side.
