Cisco (CWDMSFP1590) Multiplexer

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 enables the flexible design of highly available, multiservice networks. A Cisco CWDM SFP is a hot-swappable input and output device that plugs into an SFP port or slot of a Cisco switch or router, linking the port with the fiber-optic network. The Cisco CWDM SFPs are multirate parts that support both Gigabit Ethernet and Fibre Channel (1 Gigabit and 2 Gigabit). The SFP 1590 features, (as implied in the title) a center wavelength of 1590nm and a red band to aid in discerning between the different SFPs in its class.
