Now that 40G/100G systems have become a reality, key transceiver vendors are working hard to provide optical CFP modules that require specific signal conditioning of their electrical interfaces in order to operate properly. For CFP-based optical modules, the various 40G/100G configurations available today involve transmitting multiple optical channels in either WDM over SMF, or parallel optics run individually on parallel MMF ribbon fiber. For instance, in the case of 40G transmission, the optical signal is sent in a 4 x 10G configuration, while for 100G transmission, it is sent in a 4 x 25G or 10 x 10G configuration. In either case, the optical signal is derived inside the CFP module from individual 10.3 Gbit/s electrical lanes at the module interface, namely the CAUI or XLAUI interface. Each of the 10.3 Gbit/s CAUI lanes must be analyzed and optimized electrically to achieve the best possible performance and minimize errors that can be caused by any signal integrity issue on this interface.
