Introduction

The Cisco Coarse Wavelength-Division Multiplexing (CWDM) Gigabit Interface Converter (GBIC)/Small Form-Factor Pluggable (SFP) solution allows enterprise companies and service providers to provide scalable and easy-to-deploy Gigabit Ethernet and Fibre Channel services in their networks. The product set helps enable the flexible design of highly available, multiservice networks. 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. The Cisco CWDM GBIC/SFP solution has two main components: a set of eight different pluggable transceivers (Cisco CWDM GBICs and Cisco CWDM SFPs), and a set of different Cisco CWDM passive multiplexer/demultiplexer or optical add/drop multiplexers (OADMs). A Cisco CWDM chassis enables rack-mounting up to two of the Cisco CWDM passives.

Key Features & Benefits

• Scalability
  • The Cisco CWDM GBIC/SFP solution helps enable the transport of up to eight channels (Gigabit Ethernet or Fibre Channel) over single-mode fiber strands.

• Easy Deployment and Flexible Implementation
  • The Cisco CWDM GBIC (and Cisco CWDM SFP) fits into a standard GBIC (and SFP) port supporting the IEEE 802.3z standard on the supported Cisco Systems platforms. The Cisco CWDM OADM is passive and requires no power. Neither the Cisco CWDM GBIC (nor Cisco CWDM SFP) nor the Cisco CWDM passives requires configuration.
  • The Cisco CWDM GBIC/SFP solution allows for a variety of network configurations-from multichannel point-to-point to hub and meshed-ring configurations.

• 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.
