Transmode's evolving packet optical technology mix

• Transmode adds MPLS-TP, Carrier Ethernet 2.0 and OTN 
• The three protocols make packet transport more mesh-like and service-aware
• The 'native' in Native Packet Optical 2.0 refers to native Ethernet  

Transmode has enhanced its metro and regional network equipment to address the operators' need for more efficient and cost-effective packet transport.

“Native Packet Optical 2.0 extends what the infrastructure can do, with operators having the option to use MPLS-TP, Carrier Ethernet 2.0 and OTN, making the network much more service-aware”
