FIBER OPTIC ENCLOSURE WITH LOCKABLE INTERNAL CABLE SPOOL

CommScope Technologies LL...

1. A fiber optic enclosure assembly comprising:a housing having an interior;
a cable storage spool positioned within the interior of the housing, the cable storage spool being rotatable about an axis relative to the housing;
a fiber optic cable wound around the cable storage spool, the fiber optic cable having a connectorized first end and a connectorized second end, wherein the cable storage spool rotates about the axis relative to the housing to allow the fiber optic cable to be paid out from the cable storage spool as the second end of the fiber optic cable is pulled away from the housing; and
a fiber optic adapter receiving the first end of the fiber optic cable, the fiber optic adapter being rotatable with the cable storage spool about the axis as the fiber optic cable is paid out from the cable storage spool, the fiber optic adapter being configured to couple the first end of the fiber optic cable to a connectorized end of an optical fiber of a subscriber cable;
the fiber optic enclosure assembly having a locked configuration in which the cable storage spool is prevented from rotating relative to the housing and an unlocked configuration in which the cable storage spool is allowed to rotate relative to the housing, wherein the fiber optic enclosure assembly is configured to be set in the locked configuration independent of a position of the fiber optic adapter relative to the cable storage spool and independent of an amount of the fiber optic cable remaining on the cable storage spool.
