Cost of Complexity

Multi-link connections

Submarine link connecting to PoPs

via two terrestrial links

SDH regeneration

SLTE-terrestrial interfaces obscure

end-to-end service performance

AU3/AU4 Conversion

External boxes must be used for

DS3 and GbE mapping from

SONET to SDH and vice versa

Global solution platforms

One platform for SLTE and terrestrial

Automated service management

End-to-end provisioning & management

Multi-layer connection monitoring

Built-in AU3/AU4 mapping capability

Significant reduction in footprint and

power consumption

Ciena’s 6500 platform unifies terrestrial and submarine domains,

building one global infrastructure
