The new Cisco Optical Regenerator enables direct long-haul connectivity at OC-48 line rates between Cisco 12000 series Gigabit Switch Routers (GSRs). This eliminates the cost of deploying a network of SONET/SDH equipment.The Cisco Optical Regenerator is a bi-directional OC-48/STM-16 regenerator that supports single-mode optical fiber transmission when connected to an OC-48 line card (Packet-Over-SONET [POS] or Dynamic Packet Transport [DPT] based) in a Cisco 12000 GSR. It provides OC-48 line extensions in increments of up to 50 miles (80 km) between Cisco 12000. This new regenerator is the first IP-addressable optical regenerator with Cisco IOS (R) support. Customers can use the same command-line interface (CLI)-based network management platform for Cisco 12000 GSRs as well as for the Cisco Optical Regenerator.
