More dramatically, BitBlitz Communications Inc. announced the BBTX400 chip, which contains all the electronics for four XFP connections. This kind of chip could pave the way for quad or octal XFP cards, which could emerge as early as this spring, according to CEO Ed Rodriguez.
The chip supports either Ethernet or Sonet and consumes 5.2 watts, compared with 1.5 watts apiece for single-lane XFP electronics, says Rodriguez.
Finally, Network Elements recently announced "micromodule" technology that eventually could shrink a transceiver down to the size of a chip. This device would even attach to a board the way a chip does, using ball-grid-array connectors, doing away with the sliders and rails used in transceiver MSAs. "You can remove every last bit of mechanical cost out of the package," says Claude Denton, vice president of marketing.
Network Elements plans to use the technology for a 12km XFP module, but that's still in development. At OFC, the company will show a 300-pin-MSA module built using micromodule technology to create a very thin and inexpensive package.
Even after micromodules, the transceiver could shrink further. "Solder-on optics will be the next thing after XFP, and that's still some way out," Denton says.
