Xtera's eXpander product demonstration uses Lightwave Microsystems planar lightwave circuits and Oplink Communications fiber optic components to deliver the complete solution, making S-band a reality for backbone optical networks. This demonstration is a technological and commercial breakthrough, exemplifying the ability of the Xtera eXpander to increase usable bandwidth of optical networks by allowing fiber to carry an additional 96 channels of 10 Gb/s at 50 GHZ spacing in the previously untapped S-band.
"Xtera's patented technology, along with leading edge components from Lightwave Microsystems and Oplink, means S-band transmission will come into the mainstream," according to Xtera Chief Operating Officer, Carl DeWilde. "This demonstration shows the interoperability of S-band traffic with C-band systems, thus allowing seamless upgrades beyond initially deployed systems. In combination, the S-band and C-band will deliver the lowest cost per gigabit per kilometer for carriers."
