OPTera Metro EliminatesInterface Limitations

Other Technologies limitinterfaces to limited set

of fixed bit rates

OPTera Metro allows infinite

choice of bit rates between

50Mbps and 2.5Gbps

Other Technologies limit

interfaces to one protocol

OPTera Metro permits use of

any protocol known today or
