4 x OC-48/STM-16 Trunk

The 4 x OC-48/STM-16 Trunk Module is a high capacity 4-port trunk module well suited for use in large multiservice networks using any topography, including ring, point-point, bus, and mesh designs. It supports 100% guaranteed Quality of Service and very high bandwidth utilization. It incorporates four SFP-ports supporting OC-48/STM-16 telecommunications standards. It supports comprehensive fault and performance management, and your choice of CLI, Web GUI or SNMP management. 

You can allocate bandwidth in increments 512 kbps, allowing you to provide customers with exactly the right amount of resources based on their budgets and requirements. This also helps you optimize use of expensive infrastructure.
