The CTFS Rack Mount High Density Splice Panel provides splicing capability for up to 432 fibers. It is designed to mount directly below the Universal Patch Panel units to minimize use of rack space. An industry standard design makes the unit compatible with existing panels and frames. This module can be installed in standard 19"or 23"frames in central offices, head-ends, controlled environmental cabinets or other remote locations requiring high splicing density. There are two rack mount splice panel types, a 6 tray (4RU) and a 9 tray (6RU)
