ABSTRACT:
An assembly capable of enclosing and sealing an intermediate section of an optical fiber includes a plurality of sealing mechanisms arranged such that the assembly can be entered to gain access to electronic components for servicing without affecting an environment occupied by optical fiber broken out of an optical fiber cable. Accordingly, physical integrity of the exposed fiber, and its associated connectors and splices, is not compromised. The assembly further includes a plurality of card cages, each of which has its own integral backplane having socket connectors which allow for connection to an adjacent card cage backplane within the assembly. During initial deployment of the assembly where less than all card cages for maximum capacity are initially required to be deployed, segmenting the backplane reduces the first installed cost of the assembly. Finally, multiple alarms are provided for the assembly to alert a central office that a cover of the assembly has been removed and a humidity level within a vicinity of the broken out fiber cable exceeds a predetermined level.
