Cisco Coarse Wavelength-Division Multiplexing Extended Distance SFP Solution

The Cisco MDS 9000 family offers cost-effective multiprotocol extended distance connectivity that optimizes the use

of a customer's existing optical infrastructure through the Cisco Coarse Wavelength-Division Multiplexing (CWDM)

SFP solution (Figure 9). The Cisco CWDM SFP solution has two main components: a set of eight wavelength-

specific SFPs and a set of CWDM optical add-drop modules (OADMs). A Cisco CWDM chassis enables rack-

mounting of up to two Cisco CWDM OADMs. The Cisco CWDM OADMs are passive and require no power or

configuration.

The Cisco CWDM SFP solution enables the transport of up to eight channels over one pair of single-mode fiber

strands, enabling enterprises to increase the bandwidth of an existing optical infrastructure without adding new fiber

strands. The solution can be used in parallel with other Cisco SFP devices on the same platform.

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.
