The Cisco CWDM GBIC SFP solution is a convenient and cost-effective solution for the adoption of Gigabit Ethernet and Fibre Channel in campus,

data-center, and metropolitan-area access networks.

Because of the flexibility of the passive devices, Cisco CWDM solution helps enable the deployment of a variety of topologies to multiplex up to

eight different wavelengths on the same pair of fibers in protected or unprotected configurations. A connection between two endpoints is protected

when it is associated with two channels (typically of the same wavelength) traveling on diverse fiber routes (for example, clockwise and

counterclockwise in ring configurations or on separate fibers in point-to-point scenarios). Single-wavelength OADMs are equipped with two

channels traveling different network paths (east and west) to offer redundancy or protection in rings. On the other hand, because CWDM-MUX8A=

and CWDM-OADM4-x= have only a single network port (that is, one fiber path), two CWDM-MUX8A= or two CWDM-MUX4-x= are required

to connect to redundant (protected) fiber routes.

Figures 2 through 11 illustrate the numerous protected and unprotected deployment scenarios of the Cisco CWDM solution with the Cisco WDM

series of passive devices. The following conventions are adopted in the figures:

•

Colored circles represent transceivers (GBIC or SFP) at the corresponding color-coded wavelength connected to the filter equipment port.

•

N indicates the network port on the CWDM-MUX8A= and CWDM-OADM4-x=.

•

P indicates the pass port on the part number CWDM-OADM4-x=.

•

E and W indicate the network east and network west ports on the CWDM-OADM1-xxxx=.
