So hp XFP to SFP+ Active separates the cost of the

module was adapted for and protocols. On the datacom side, three additional hot-pluggable form factors were introduced: XENPAK, XPAK, and X2 for 10 Gigabit Ethernet (see Table). But both the telecom and datacom markets are now starting to migrate to hp XFP to SFP+ Active, bringing about a reconvergence that embraces core switching/routing applications  with enterprise applications soon to follow.The hp XFP to SFP+ Active module is an ultra-small, hot-pluggable, 10-Gbit/sec optical transceiver form factor that was standardized by the XFP Group to help drive cost and power consumption out of 10-Gbit/sec optical networking applications, while enabling rapid advances in port density.hp XFP to SFP+ Active specifies transceiver operation, so the electrical and optical data are both serial. 300-pin, XENPAK, XPAK, and X2, in contrast, are transponders and have an integral SERDES to map several lower-rate parallel electrical streams into a higher-rate serial optical stream, and vice versa. So hp XFP to SFP+ Active separates the cost of the SERDES chip from the optical module, allowing independent optimization and lower-cost optical sparing. Even better, SERDES chips that drive multiple hp XFP to SFP+ Active are now emerging, further reducing the cost per XFP port.
