Fiber optic closure

Abstract

A fiber optic communications arrangement includes a closure with an interior volume; the closure including at least one cable through-port in communication with the interior volume; and an expansion component attached to an exterior portion of the closure and having an interior region in communication with the closure interior volume. The expansion component includes ruggedized fiber optic adapters mounted thereto. Each of the ruggedized fiber optic adapters includes at least one connector port for receiving ruggedized fiber optic connectors.

         11 . A fiber optic communications arrangement comprising: (a) a closure with an interior volume; the closure including at least one cable through-port in communication with the interior volume, the closure being adapted to be installed initially having a first configuration; and (b) a module that is adapted to be attached to the closure at a date after initial installation to convert the closure from the first configuration to a second configuration, the module being arranged to be attached to an exterior portion of the closure and having an interior region in communication with the closure interior volume, the module including at least one ruggedized fiber optic adapter mounted thereto; the at least one ruggedized fiber optic adapter including at least one connector port for receiving a ruggedized fiber optic connector. 
     
     
         12 . The arrangement of  claim 11  wherein the module includes an optical power splitter. 
     
     
         13 . The arrangement of  claim 11  wherein the module includes an optical wavelength splitter. 
     
     
         14 . The arrangement of  claim 11  wherein the module includes passive components. 
     
     
         15 . The arrangement of  claim 11  wherein the closure includes one or more splice trays. 
     
     
         16 . The arrangement of  claim 11  wherein the closure has a plurality of through-ports. 
     
     
         17 . The arrangement of  claim 16  further including a cable sealing arrangement within the closure, the sealing arrangement including a sealing material. 
     
     
         18 . The arrangement of  claim 17  further including an actuator configured and arranged to cause the sealing material within the closure to be compressed and deform radially inwardly about fiber optic cables when laid within the through-ports, thereby forming circumferential seals around fiber optic cables. 
     
     
         19 . The arrangement of  claim 11  wherein the module includes a plurality of expansion housings, with the ruggedized fiber optic adapters mounted to the expansion housings. 
     
     
         20 . The arrangement of  claim 19  wherein: (a) the closure defines a central longitudinal axis extending along a length of the closure from a bottom end and a top end; the bottom end being defined by a base, and the top end being defined by a dome; and (b) the expansion housings are positioned on opposite sides of the axis.
