Dense Wavelength Division Multiplexing (DWDM) Small Form-Factor Pluggable (SFP) transceivers provide the high speeds and physical compactness that today's networks require while delivering the deployment flexibility and inventory control that network administrators demand. Our DWDM SFPs are available in all 100 GHz C-band wavelengths on the DWDM ITU grid. They are designed to Multi-Source Agreement (MSA) standards to ensure broad network equipment compatibility. As multirate interfaces they support any protocol from 100 Mbps to 4.25 Gbps. The EOLS-16xx-xx transceivers are small form factor pluggable modules for bi-directional serial optical data communications such as 4x/2x/1x Fibre Channel, SDH/SONET, Ethernet applications.The modules are hot pluggable and digital diagnostic functions area vailable via an I2C serial bus specified in the SFP MSA SFF-8472. The modules meet the requirements of the IEEE802.3 Gigabit Ethernet standard and ANSI Fibre Channel specifications, and are suitable for interconnections in Gigabit Ethernet and Fibre Channel environments. DWDM modules operate at nominal Dense Wavelength Division Multiplexing(DWDM) wavelengths. 45 wavelengths are available from 1529.55nm–1564.68nm in a100GHz (~0.8nm)channel spacing. The DWDM characteristics are fully compliant to the wavelength parameters specified in ITU standards G.692 and G.694.1
