There is provided splice trays and splice assemblies that provide convenient access to optical fiber slack within a relatively small area or volume. Some splice trays are adapted for use with microstructured optical fibers to further reduce the size of the splice tray or splice assembly. Some splice trays provide fiber routing devices on the cover of the splice tray. The fiber routing device may be positioned on an inside surface of the cover and/or on an outside surface of the cover. The splice trays and/or splice assemblies may be used with or as fiber drop terminals used within multiple dwelling units.
