Abstract

A connector port is adapted for a (NID) to receive a connectorized optical fiber from inside the NID and a pre-connectorized drop cable from outside the NID. An exterior connector port includes a base positioned within an opening defined by an external wall of the NID, a mount on the base and a connector receptacle secured to the mount adjacent the external wall. An interior connector port includes an insert positioned within an opening defined by an external wall of the NID, a bracket mounted inside the NID and a connector receptacle secured to the bracket. A connector port also includes an insert positioned within an opening defined by a wall of the NID and a connector port secured to the insert. The connector port permits a field technician to readily connect, disconnect and reconfigure optical connections between the connectorized optical fiber and the pre-connectorized drop cable in the field.

5. The exterior connector port according to claim 3, wherein the connector receptacle is secured to the base by one of a threaded nut, a snap-fit and a press-fit.

6. The exterior connector port according to claim 3, wherein the connector receptacle is accessible to the field technician only when a service provider access door provided on the network interface device is opened and the cover is removed from over the base.

7. The exterior connector port according to claim 3, further comprising a connector adapter sleeve disposed within the connector receptacle for aligning the connectorized optical fiber with an optical fiber of the pre-connectorized fiber optic drop cable.

8. An interior connector port for use in an optical network and adapted for a network interface device to optically connect a connectorized optical fiber from inside the network interface device to a pre-connectorized fiber optic drop cable from outside the network interface device, the interior connector port comprising:

a bracket mounted inside the network interface device; and

a connector receptacle secured to the bracket, the connector receptacle comprising a first end for receiving the connectorized optical fiber and a second end for receiving the pre-connectorized fiber optic drop cable;

wherein the interior connector port is operable to permit a field technician to readily connect disconnect and reconfigure the pre-connectorized fiber optic drop cable from inside the network interface device without the need for splicing.

9. The interior connector port according to claim 8, wherein the connector receptacle is accessible to the field technician only when a service provider access door provided on the network interface device is opened.

10. The interior connector port according to claim 8, further comprising a connector adapter sleeve disposed within the connector receptacle for aligning the connectorized optical fiber with an optical fiber of the pre-connectorized fiber optic drop cable and for maintaining the connectorized optical fiber and the optical fiber of the pre-connectorized fiber optic drop cable in physical contact.

11. A connector port for use in an optical network and adapted for a network interface device to optically connect a connectorized optical fiber from inside the network interface device to a pre-connectorized fiber optic drop cable from outside the network interface device, the connector port comprising:
