  2. conference & convention enabling the next generation of networks & services OUTLINE Development of next generation SLTE ● Development Concept ● Development Concept ● Easy Operation ● Flexible Configuration ● 40G&100G Technology

  3. conference & convention enabling the next generation of networks & services Development Concept Comparison to conventional SLTE ● Minimum configuration 8w x 10G in ETSI 3 racks Footprint less than 1/2 ● Not a critical failure for 5years (after original shipping) ● Not a critical failure for 5years (after original shipping) Similar high reliability with redundant function ● A lot of records of existing systems upgrade Flexible configuration and easy operation especially for existing system upgrade
