ClariPhy Communications, Inc., a
fabless semiconductor company specializing in high speed communications
ICs, has announced shipment of its CL1012 clock and data recovery
(CDR) IC with maximum likelihood sequence estimation (MLSE) into line
cards with Tunable XFP and XFP+ modules for 10 Gb/s optical networking.
As video and other consumer applications dramatically increase the
demand for bandwidth in telecommunications networks, equipment vendors
are responding with higher density, higher performing DWDM platforms.
The transition from 300 pin to tunable XFP optical modules more than
doubles port density, while the incorporation of MLSE-based electronic
dispersion compensation (EDC) on the line card significantly increases
reach and tolerance to impairments while reducing network costs.
âThe Tunable XFP+ ecosystem continues to mature with the availability of
Tunable XFP+ modules from JDSU and an MLSE IC from ClariPhyâ
ClariPhy and JDSU will demonstrate a tunable XFP+ solution, using JDSUâs
optical modules and ClariPhyâs CL1012 IC, at the OFC 2010 conference in
San Diego, March 22-25. The demonstration will take place in ClariPhyâs
private suite.
âThe Tunable XFP+ ecosystem continues to mature with the availability of
Tunable XFP+ modules from JDSU and an MLSE IC from ClariPhy,â said Tom
Fawcett, Senior Director of Marketing, Transmission Modules at JDSU.
âLine cards using JDSUâs Tunable XFP+ modules and ClariPhyâs CL1012 IC
will deliver the density and performance that the market demands.â
The â+â 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
proven benefits of MLSE are fully realized with the + version of the
module. These benefits include improved tolerance to major impairments
in telecom networks â 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 by reducing or eliminating expensive and bulky optical
dispersion compensation equipment, avoiding the need for fiber
characterization, and enabling the use of a greater percentage of their
installed fiber.
âWe are excited to participate with JDSU in the emerging Tunable XFP+
ecosystem,â said Dr. Paul Voois, Co-founder and CEO of ClariPhy. âJDSUâs
tunable XFP and XFP+ modules set a new benchmark in achievable port
density in DWDM equipment, while the high tolerance of the CL1012 to CD
and PMD will enable carriers to lower their operational costs by
avoiding the need for expensive optical dispersion compensation gear and
time-consuming fiber characterization effort.â
The CL1012 is available now. The device is packaged in a 10×10 mm,
144-pin BGA and dissipates less than 2 watts of power. A CL1012
evaluation board is also available. This board includes an XFP cage and
enables rapid evaluation of the benefits of the CL1012 for a tunable
XFP+ application.
