T-XFP+

ClariPhy is the pioneer supplier of EDC solutions used by leading tunable XFP line card (T-XFP-LC) suppliers to cut cost, lower system power, and mitigate troublesome chromatic dispersion (CD) and polarization mode dispersion (PMD).   The ability to tune to a new frequency means module suppliers and system integrators can displace fixed-wavelength dense wavelength division multiplexing (DWDM) 300-pin MSA and XFP transponders with new T-XFP based modules.  The most optimal approach to increase port density and double the reach is by using the CL1012 in a T-XFP+ configuration.

The “+” in XFP+ refers to an optical module with a linear interface in its receive path, which enables the full performance benefit from an EDC IC on the line card that the module plugs into. This is analogous to SFP+, which supports a linear interface and is the leading optical module for 10G Ethernet applications.

While the CL1012 IC supports both XFP and XFP+ tunable modules, the “+” solution maximizes your tolerance to major impairments in telecom networks including chromatic dispersion (CD), first and second order polarization mode dispersion (PMD), and nonlinear distortion.  The CL1012 has ½ the power and ¼ the area of competing MLSE solutions, and achieves higher performance by design than alternative EDC architectures such as decision feedback equalization.

Carriers deploying the CL1012 and tunable XFP+ modules in their transport platforms will realize both opex and capex savings from day one.  Carriers will both eliminate expensive and bulky optical dispersion compensation equipment (DCE) while avoiding the need to send a truck to characterize each fiber run.  The T-XFP ecosystem is emerging with the market expected to hit up to $500M in 2012.
