Figure 10 shows a common point-to-point deployment scenario for the Cisco MDS 9000 family using the Cisco
CWDM SFP solution. Two endpoints are directly connected through a fiber link. The Cisco CWDM SFP solution
enables customers to add or drop up to eight channels onto a pair of single-mode fiber strands. As a result, the need
for additional fiber is reduced. Redundant point-to-point links can be implemented by adding or dropping redundant
channels onto a second pair of single-mode fiber strands.
