10 Gbps Silicon Device

The Hudson (S19203) is a 10 Gbps silicon device designed to support both the evolving G.709 digital wrapper standard and traditional SONET/SDH infrastructures. The Hudson variable rate, digital wrapper framer/deframer and performance monitor device facilitates the transparent transport of multiple protocols across the network, while aiding interconnection between multiple carriers. The device incorporates programmable Forward Error Correction (FEC) for rates up to 10.66 Gbps and supports OC-192 transmission standards. The digital wrapper technology provides an extension of the current SONET/SDH infrastructure, while enhancing both flexibility and transparency across the network. The device interfaces with the company's 10 Gbps mux/demux devices, SONET/SDH/digital wrapper backplane devices and mapping and pointer processing devices.

The device's core logic runs on a 1.8V power supply and features two input and two output ports, which are configurable in many ways. The input and output ports can be configured as a dual redundant I/O on a single data stream for protection switching or as two completely independent data streams for duplex operation. Either input port can be directly connected to either output port for loopback testing.

The device provides full digital wrapper performance monitoring and features Optical Channel Overhead (OCh-OH) insertion and extraction, which are independently controllable. All 64 OCh-OH bytes in a superframe are programmable in function and are available for insertion from and drop to FPGA or microprocessor. Data entering and leaving the device can be optionally differentially decoded and encoded, deframed and framed, descrambled and scrambled, and decoded and encoded with FEC information. In addition, SONET data can optionally be performance monitored for integrity, alarms, and trace messages.
