…Among the interesting quotes from his presentation were: * “Ethernet has accomplished something that SONET and SDH never did, global ubiquity.”   * “The world of SONET and SDH stops at 10G and 40G. The world of 100G belongs to Ethernet and OTN. The world is changing, and this is the…

…  The reason is that as optical networks get to speeds of 100G and service providers begin to deploy 100 gigabit Ethernet (100GbE), traditional SONET/SDH protocols are no longer viable for the transport layer, leaving OTN as likely the only optical transport protocol capable of supporting 100GbE services…

…demand drives new requirements. Additionally, the universal adoption of GFP for Ethernet mapping to SONET/SDH drives efficiencies by allowing handoff of standard SONET signals across platforms and other SONET networks.

Cable operators' Hybrid Fiber-Coax (HFC) plants pass within half a mile of some 80 percent of business locations. Therefore, extending the fiber plant to reach mid-sized to large businesses has never been easier or more rewarding. But what is the best way to aggregate, transport and switch the services for these customers?

Features & benefits * Transparent multiplexing of low-rate SONET/SDH signals onto a single wavelength * Minimized per-port cost of OC-48 based connections over a DWDM network by combining four OC-48 signals onto a single wavelength * Hot-swappable into any slot for any service mix * ADM capability…

…Line Switched Rings (BLSR) traffic. Additionally, an on-board SONET switch matrix provides STS-1 granularity for grooming at POP hand-off points. Two 10G SONET/SDH ADM cards can be mated in a shelf to function as a linear or ring SONET node capable of providing 1+1 or BLSR/MS-SPRING overlaid sub-networks…
