Nortel Networks has added a 10-gigabit muxponder card to its "Optical Metro 5100/5200" dense-wave-division-multiplexing product.

The vendor said the module will be available in July, and it will offer a 40% savings in capital expenses.

Nortel added that each muxponder card can support more than 2,000 digital-video streams as cable operators look to expand video-on-demand rollouts.
