Abstract

The following text deals with an improved embodiment of an enclosure for mechanical fiber splices and fiber management. The new splice box can be used in various optical circuit packs. The suggested version has a metal enclosure, e.g. stainless steel. A special embodiment of a steel sheet metal splice box is shown in the figures 1 - 3. The box is capable of holding some meters of fiber pigtails, and it can easily store several mechanical splices. The curves and loops are designed to maintain a minimum fiber bend radius after routing the fibers in the box to minimize optical loss. The sample consists of a welded base assembly and a removable lid to close the box after mounting the splices and routing the fibers. The base part provides e.g. two separate sets of mounting holes and is designed to be stackable if needed. The proposed embodiment has various openings on the side walls to run the fiber in and out from different locations. The base assembly consists of few individual pieces which can be welded together.

The following text deals with an improved embodiment of an enclosure for mechanical fiber splices and fiber management. The new splice box can be used in various optical circuit packs.

The suggested version has a metal enclosure, e.g. stainless steel. A special embodiment of a steel sheet metal splice box is shown in the figures 1 - 3. The box is capable of holding some meters of fiber pigtails, and it can easily store several mechanical splices. The curves and loops are designed to maintain a minimum fiber bend radius after routing the fibers in the box to minimize optical loss. The sample consists of a welded base assembly and a removable lid to close the box after mounting the splices and routing the fibers. The base part provides e.g. two separate sets of mounting holes and is designed to be stackable if needed. The proposed embodiment has various openings on the side walls to run the fiber in and out from different locations. The base assembly consists of few individual pieces which can be welded together.

The new metal splice box has got certain advantages compared to especially a plastic version. Foremost, being metallic is a major factor for passing a fire test (e.g. Network Equipment Building System fire spread testing NEBS3i GR-63)...
