Abstract
Market demand for 40Gbit/s is clear now
relevant technologies are mature
cost is close to the threshold of taking off and mass deployment will start soon. Market demand for ASON is showing up
relevant technologies are mature in major parts and mass deployment will start soon. Metro carrier grade Ethernet technologies already have necessary features and performances of public telecom applications and become major development direction for metro consolidation and access layers. PON based FTTx gradually becomes the major option for broadband access technologies
however
different applications are employed in different scenarios. EPON is mature and GPON is close to mature
which still needs more attention and promotion of industries.
