1.12.2.2 40-Channel Patch-Panel Tray
The 40-channel patch panel tray is 2 RUs deep and comes preinstalled with MPO-LC cables. The
40-channel patch-panel tray can host up to 10 ribbon cables (with eight fibers each), for a total of 80
connections, and is used with expanded ROADM, terminal, hub, and mesh nodes. Expanded hub and
ROADM nodes will typically require two 40-channel patch-panel modules each; terminal nodes require
one 40-channel patch-panel tray; and one 40-channel patch-panel tray is needed for mesh nodes for each
direction.
The module fits 19- and 23-inch (482.6-mm and 584.2-mm) ANSI racks and 600 mm (23.6 inch) x
300 mm (11.8 inch) ETSI racks, using reversible brackets.
Figure 1-44 shows a 40-channel patch-panel tray.
