What is a Fiber Optic Splice Tray?

Fiber optic fusion and mechanical splices are placed in mechanical closures that are referred to as “splice enclosures”, “splicing trays” or “splicing organizers”. Fiber optic splice trays are designed to provide a location to store and to protect the fiber cables and the splices.

Fiber optic splice trays are located at  intermediate points along a route where cables are required to be joined or at the termination and patch panel points at the end of fiber cable runs.

Splice trays normally hold up to 12 splices, and several trays are used together to splice a large fiber cable. Each tray provides space for mounting fiber splice protectors and excess fiber.

Fiber buffer tubes enter the splice tray fiber optic plc splitter 1×8 at one end only. At this end, the buffer tubes stop and are secured to the tray where the individual fibers are exposed.

If some fibers need to be routed to a different tray, proper buffer tube splitters should be used. Unprotected fibers should not be exposed outside the splice tray.

Fiber splice trays can be optical wavelength sensitive. A splice tray designed for only 810nm wavelengths may cause optical loss if 1550nm wavelengths are used. So check your splice tray manufacturer’s specification before use it.

To add splice trays, align the tray pins with the holes in the base bracket. Squeeze the tray pins and slip the tray into the base bracket.

To remove splice trays, reverse this procedure. Use a screwdriver to pry the hinge away from the bracket if necessary or as required.
