1.12.4 Fiber Management Using the Fiber-Storage Tray

Figure 1-48
Figure 1-48
To ensure diversity of the fiber coming from different cards in the Y-cable scheme, one pair of fibers
(e.g. from the active transponder) should come out on the opposite side from the second pair of fibers
(e.g. standby transponder), according to local site practice.
1.12.4 Fiber Management Using the Fiber-Storage Tray
Cisco recommends installing at least one fiber-storage tray in multinode racks to facilitate fiber-optic
cable management for DWDM applications. This tray is usually used to store slack cable from cables
installed between cards within a single node. Refer to
locations.
