摘要:
A telephone terminal box which is divided into two compartments so to provide a first compartment accessible only to the telephone operating company and a second compartment accessible to the subscriber. Each compartment has its own cover, and the covers may be individually locked by the subscriber and by the telephone company. The box is constructed so that if it becomes necessary, the telephone company can gain access to the subscriber compartment, however, the subscriber cannot gain access to the telephone company compartment. A terminal block is mounted in the subscriber compartment to provide connections to a predetermined number of subscriber telephones. A protector block is mounted in the telephone company compartment, the terminal block being wired at the factory to one side of the protector block. Another set of wires connects contacts from the protector block to an appropriate module mounted within the telephone company compartment, and which is spliced to permit the leads of a telephone cable to be connected to the protector block. Gaskets are provided around the internal peripheral surfaces of the covers to form a water-tight seal when the covers are closed so that the box may be mounted externally of a building, if so desired.

A fiber distribution device includes a swing frame chassis pivotally mounted to a support structure. At least a first optical splitter module is mounted to the swing frame chassis. Pigtails having connectorized ends are carried by the swing frame chassis and have portions that are routed generally vertically on the swing frame chassis. An optical termination field includes fiber optic adapters carried by the swing frame chassis. The fiber optic adapters are configured to receive the connectorized ends of the pigtails.

A waterproof panel comprises a front wall, a back wall, a front baffle assembly and a back baffle. A cavity is defined between the front wall and the back wall, the front baffle assembly and the back baffle are received in the cavity. The front wall defines a first hole array and a second hole array, the back wall defines a third hole array in same height with the second hole array. The front baffle assembly fixed on one side of the second hole array near the third hole array comprises a main baffle. The back baffle fixed on one side of the third hole array near the second hole array is on one side of the main baffle near the second hole array. The back wall comprises a plurality of protruding strips, which can rebound water entering through the third hole array back.

A modular rack controller for an intelligent patching system includes a base unit comprising a processor and memory that monitor and log patch cord connectivity in the patching system, and a separate display unit comprising a user interface. The base unit and display unit are in electrical communication with each other via a patch cord, and the display unit displays patch cord connectivity information monitored by the base unit. The rack controller may include a separate Ethernet interface unit that allows the rack controller to communicate with other rack controllers. A mounting bracket having front and rear sides is mounted to a patch panel rack. The display unit is secured to the front side of the mounting bracket and the base unit is secured to the rear side of the mounting bracket. The mounting bracket may have a hinge that pivots the display unit relative to a patch panel rack.

A fiber distribution hub includes a frame within the enclosure, the frame having a swinging portion configured to pivot from a first position to a second position. The fiber distribution hub also includes a subscriber termination field mounted on the swinging portion; at least one optical splitter mounted on the frame; and a pigtail fiber routed from the optical splitter. The swinging portion swings from the first position to the second position without increasing a distance for routing the pigtail fiber from the optical splitter to a first front termination connection.
