High Availability
The Cisco CWDM GBIC/SFP solution takes advantage of a multichannel architecture and the inherent protection of ring architectures. The solution
helps enable:
•
Use of Layer 2 and Layer 3 redundancy and failover mechanisms at the channel endpoints (Cisco CWDM GBIC/SFP) to build highly available
links
•
Use of two-path link configurations in a ring architecture to provide protection from fiber cuts
Investment Protection
The Cisco CWDM GBIC/SFP solution helps enable enterprises and service providers to increase the bandwidth of an existing Gigabit Ethernet
optical infrastructure without adding new fiber strands. The solution can be used in parallel with other Cisco GBIC and SFP devices on the same
platform.
DEPLOYMENT SCENARIOS
Point-to-Point Configuration
In a point-to-point configuration (Figure 2), two endpoints are directly connected through a fiber link. The Cisco CWDM GBIC/SFP solution helps
enable customers to add or drop as many as eight channels (Gigabit Ethernet or Fibre Channel) into a pair of single-mode fiber strands. As a result,
the need for additional fiber is minimized. Redundant point-to-point links are possible by adding or dropping redundant channels into a second pair
of single-mode fiber strands.
A single fiber point-to-point configuration also is possible (Figure 3). By using different wavelengths to transmit and receive signals, as many as four
channels can be transported over a single fiber strand.
The main applications for the architecture are enterprise campus links and service provider point-of-presence (POP) or hub interconnects across a
metropolitan (metro) area.
