## Abstract

A fiber management tray (20) is disclosed. The fiber management tray (20) includes a tray body (22) defining a fiber storage region (24) for storing excess optical fiber length (26). The tray body (22) also includes a splice mount (28) for mounting at least one optical splice (30). The fiber management tray (20) includes a restricted access region (32) and an unrestricted access region (34) on the tray body (22). The splice mount (28) and the fiber storage region (24) are provided at the unrestricted access region (34), and an optical splitter component (36) is provided at the restricted access region (32).

## Claims

### Claim 1

A fiber management tray comprising a tray body defining a fiber storage region for storing excess optical fiber length, the tray body also including a splice mount for mounting at least one optical splice, wherein the fiber management tray includes a restricted access region and an unrestricted access region on the tray body, the splice mount and the fiber storage region being provided at the unrestricted access region, and an optical splitter component being provided at the restricted access region.

### Claim 2 (depends on 1)

The fiber management tray of claim 1, wherein an input optical fiber of the optical splitter component extends outwardly from the restricted access region into the unrestricted access region.

### Claim 3 (depends on 1)

The fiber management tray claim 1, wherein the optical splitter component includes a splitter body and splitter output fibers that extend outwardly from the splitter body, and wherein the restricted access region includes a first portion that restricts access to the splitter body and a second portion that restricts access to the splitter output fibers.

### Claim 4 (depends on 3)

The fiber management tray of claim 3, wherein the tray body includes a fiber exit/entrance location, wherein the splitter output fibers extend along a fiber routing path that extends a first distance measured from the splitter body to the fiber exit/entrance location, and wherein the second portion of the restricted access region extends along a majority of the first distance.

### Claim 5 (depends on 4)

The fiber management tray of claim 4, wherein the second portion of the restricted access region extends substantially the entire first distance between the splitter body and the fiber exit/entrance location.

### Claim 6 (depends on 4)

The fiber management tray of claim 4, wherein the second portion of the restricted access region extends along a peripheral boundary of the tray body.

### Claim 7 (depends on 6)

The fiber management tray of claim 6, wherein the second portion of the restricted access region is position between the peripheral boundary of the tray and the fiber storage region.

### Claim 8 (depends on 3)

The fiber management tray claim 3, wherein the second portion of the restricted access region is curved.

### Claim 9 (depends on 1)

The fiber management tray claim 1, wherein the fiber storage region defines a fiber loop path.

### Claim 10 (depends on 3)

The fiber management tray claim 3, wherein the fiber storage region is positioned between the splice mount and the splitter body.

### Claim 11 (depends on 4)

The fiber management tray claim 4, wherein the splice mount is positioned adjacent to the fiber exit/entrance location.

### Claim 12 (depends on 4)

The fiber management tray claim 4, wherein the tray body includes a hinge location at which the tray body pivotally connects to a tray mounting plate, wherein the hinge location is positioned adjacent to the fiber exit/entrance location, wherein the tray body has an obround shape when viewed in plan view, wherein the tray body defines a major dimension that extends along a major axis of the tray body and a minor dimension that extends along a minor axis of the tray body, wherein the major and minor axes are perpendicular relative to one another, and wherein the splitter body and the splice mount are positioned on opposite sides of the major axis and are bisected by the minor axis.

### Claim 13 (depends on 1)

The fiber management tray claim 1, wherein the splitter component is an optical power splitter or a wavelength division multiplexer.

### Claim 14 (depends on 1)

The fiber management tray claim 1, wherein access to the restricted access region is restricted by a cover secured to the tray body.

### Claim 15 (depends on 1)

The fiber management tray claim 1, wherein access to the restricted access region is restricted by a cover secured to the tray body, and wherein the cover is either permanently connected to the tray body or the fiber management tray includes a tamper indicator for providing an indication as to whether the cover has been removed.
