## Abstract

A fiber optic telecommunications frame is provided including panels having front and rear termination locations, the panels positioned on left and right sides of the frame. The frame includes vertical access for the rear cables. The frame further includes left and right vertical cable guides for the front patch cables. The frame further includes cable storage spools for the patch cables. The frame includes a horizontal passage linking the left and right panels and the cable guides. A portion of the frame defines splice tray holders and a central passage from the splice tray holders to the rear sides of the left and right panels. From a front of each panel, access to a rear of the panel is provided by the hinged panels. Alternatively, the panels can form connector modules with front termination locations and rear connection locations for connecting to the rear cables. The modules can house couplers, such as splitters, combiners, and wave division multiplexers. The termination locations can be located on the same side of the frame as the splice tray holders, or on an opposite side. An enclosure of the frame included hinged or otherwise moveable panels to allow access to the terminations or the splice trays.

## Claims

### Claim 1

A telecommunications apparatus comprising:
a frame defining a first area and a separate second area;
a plurality of modules that mount at the first area of the frame, each of the modules including a module housing containing at least one splitter, each of the modules including a plurality of fiber optic adapters positioned at fronts of the module housings, the fiber optic adapters each including inner and outer aligned openings for receiving fiber optic connectors, the inner openings being accessible from inside the module housings and the outer openings being accessible from outside the module housings, the modules also including first optical fibers that extend from the splitters and have connectorized ends positioned within the inner openings of the fiber optic adapters;
a panel positioned at the second area of the frame, the panel being pivotally connected relative to the frame by a hinge; and
second optical fibers having connectorized ends carried with the panel.

### Claim 2 (depends on 1)

The telecommunications apparatus of claim 1, further comprising one or more doors that pivot relative to the frame, the one or more doors protecting the first and second areas when in a closed position and that allow access to the first and second areas when in an open position.

### Claim 3 (depends on 1)

The telecommunication apparatus of claim 1, wherein the modules each include a single row of the fiber optic adapters.

### Claim 4 (depends on 1)

The telecommunication apparatus of claim 1, wherein the connectorized ends of the second optical fibers are received within fiber optic adapters mounted on the panel.

### Claim 5 (depends on 4)

The telecommunications apparatus of claim 4, wherein patch cords are routed from the fiber optic adapters mounted on the panel to the fiber optic adapters of the modules.

### Claim 6 (depends on 1)

The telecommunications apparatus of claim 1, further comprising a plurality vertically spaced-apart spool structures positioned between the first and second areas for storing excess optical fiber.

### Claim 7 (depends on 6)

The telecommunications apparatus of claim 6, wherein the optical fiber is stored in half-loops.

### Claim 8 (depends on 1)

The telecommunications apparatus of claim 1, wherein the second optical fiber correspond to at least one outside plant cable.

### Claim 9 (depends on 1)

The telecommunications apparatus of claim 1, wherein the module housings include spaced-apart and parallel major side walls and spaced-apart and parallel minor side walls that cooperate to define interior regions of the module housings, wherein the splitters are positioned within the interior regions, and wherein the major and minor side walls extend between the fronts of the module housings and rears of the module housings.

### Claim 10 (depends on 9)

The telecommunications apparatus of claim 9, wherein the modules each include a single row of the fiber optic adapters, and wherein the fiber optic adapters have cross-dimensions that extend a majority of a distance defined between the major side walls of the module housings.

### Claim 11 (depends on 1)
