The following DWDM wavelength topologies are also supported:
• meshed ring
• hubbed ring
• point-to-point
Interworking
• OPTera Metro 5000-series Multiservice Platform (Release 6.1)
Note: UPSR, BLSR, and 1+1 linear protection schemes for OPTera Metro
3500 signals pass through OPTera Metro 5000 network segments
transparently. Logical UPSRs, BLSRs and 1+1 linear configurations are
possible across both OPTera Metro 3000 and 5000 DWDM networks.
— OPTera Metro 3500 Gigabit Ethernet and Fibre Channel services (GFP
