Generic Requirements for Fiber Demarcation Boxes

Document Number GR-2898
Issue Number 02
Issue Date Dec 1999

    ABSTRACT: Fiber demarcation boxes provide an interface between the telecommunication provider's network and individual customer cables. Fiber
    demarcation boxes are typically located on the customer's premises in controlled environments such as building basements or
    telecommunications equipment closets. However, as demand for field access to fiber networks grows, and as fiber components become more
    robust, fiber demarcation boxes will become increasingly more common in the outside plant. Fiber demarcation boxes typically provide
    one or more of the following features or functions: a patch panel for performing fiber rearrangement, interconnect between the
    telecommunications plant and customer service cables, rack-mountable fiber distributing frame and shelves, fiber test access point, and
    splice storage and management facility for fiber pigtails.

    GR-2898, Generic Requirements for Fiber Demarcation Boxes, sets for the Telcordia view on generic requirements and design
    considerations for fiber demarcation boxes to meet the needs of telecommunications network providers.
