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

Conclusion

We have developed next generation SLTE

Transmission capacity

180w x 10Gb/s with 25GHz spacing 90w x 40Gb/s with 50GHz spacing 90w x 40Gb/s with 50GHz spacing

Correspond to the multi channel spacing,

modulation format, and bit rate

Improvement of flexibility, and operability
Allow small start in ETSI 1rack
Available 100Gb/s tributary in the same platform
