The Optical Metro 4100, 4150 and 4200 Multiservice Next Generation SDH platforms comprise a family of full access STM-4/16 SDH multiplexers. DWDM aggregates can be used to further extend capacity to 10 Gbit/s. Key attributes are small footprint, full access, mixed payload, virtual concatenation, a fully non-blocking 4/3/1 cross-connect and proven deployment with network elements installed globally. In-service upgrade is available across the Optical Metro 4000 family.

• Accommodates more traffic in fewer shelves and racks, resulting in up to 30% floor space savings because of its architecture and high port density.
• Supports native rate data interfaces. The fast Ethernet interface with virtual concatenation tunable bandwidth unleashes new Ethernet Private Line service revenue opportunities for Internet Access and LAN extension applications.
• A single shelf can subtend and close multiple protected STM-n rings/spurs and perform fully non blocking VC-12 cross connection for unrestricted bandwidth management.
• Provides tributary access to full STM-4 and STM-16 protected payload and flexible aggregation for narrow and broadband services.
• Supports full remote downloads for upgrading thousands of network elements from a single centralized location
