Abstract

There is provided splice trays and splice assemblies that include one or more optical fiber routing guides for optical fiber slack storage. The optical fiber routing guides are associated with individual or select groupings of splice holders in order to eliminate slack storage generally around the perimeter of the splice tray. Therefore, the optical fibers of one or a select number of splices may be routed separately from other optical fibers to enable technicians to more easily manipulate the fibers. In addition, optical fiber routing guides are included with a splice assembly in order to eliminate slack storage generally around the splice tray. The optical fiber routing guides additionally may define bend radiuses of between about 0.1 inch and about 0.5 inch. Therefore, splice trays and splice assemblies comprising the optical fiber routing guides may provide more convenient access and/or define smaller sizes compared to previous splice trays and splice assemblies.

Claims

1. A splice tray for accommodating at least one splice of two or more optical fibers, the splice tray comprising:

at least one splice holder joined to the splice tray, wherein the at least one splice holder is adapted to selectively receive a splice that optically connects a first optical fiber and a second optical fiber, wherein the splice tray is configured to receive a plurality of splices; and

at least one or more optical fiber routing guides each associated with a single respective splice;

wherein the optical fiber routing guide is adapted to provide slack storage for only the optical fibers associated with the single respective splice wherein the splice defines opposed axial ends, and wherein a respective optical fiber routing guide comprises a generally semicircular hub proximate each axial end of the respective splice.

2. A splice tray according to claim 1 further comprising a splice organizer, wherein the at least one splice holder is defined in the splice organizer.

3. A splice tray according to claim 1, wherein the splice tray comprises an optical fiber routing guide associated with each splice of the splice tray.

5. A splice tray according to claim 1, wherein at least one of the two optical fibers comprises a bend performance optical fiber.

6. A splice tray according to claim 1, wherein the at least one optical fiber routing guide defines a bend radius of about between about 0.1 inch and about 0.5 inch.

7. A splice tray according to claim 1, wherein the at least one optical fiber routing guide defines a bend radius of about 0.2 inch.

4. A splice tray for accommodating at least one splice of two or more optical fibers, the splice tray comprising:

at least one splice holder joined to the splice tray, wherein the at least one splice holder is adapted to selectively receive a splice that optically connects a first optical fiber and a second optical fiber, wherein the splice tray is configured to receive a plurality of splices; and

at least one or more optical fiber routing guides each associated with a single respective splice;
