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
in the future
