The two Port OC-3/STM-1 Trunk Module is ideal for connecting any of Media Links’ MD8000 devices to SONET/SDH networks at rates of 155Mbps. Using a non-blocking Layer 2 Switch Fabric, Ethernet frames from an OC-3/STM-1 Trunk Module are sent to the dual Switch Controllers (SW-CNT modules) across the chassis backplane. For route diversity, this trunk module is equipped with dual SONET/SDH interfaces.

For efficient multiplexing and easy integration with carrier IP networks, the trunk card supports the ITU G.7041 Generic Framing Procedure (GFP). Various concatenation modes are also supported, including VC4 only within SDH STS/VC concatenation modes. For SONET, the logical path can be defined as 1 x STS-3 or 3 x STS-1, delivering optimal core network utilization and multi-service termination on a single trunk port.

The two Port OC-3/STM-1 Trunk Module accepts small form factor pluggable (SFP) optics to support optical budgets of 10km, 40km, 80km and 120km. Newer SONET/SDH compatible wavelength division multiplexing technologies such as CWDM/DWDM are also fully supported.
