The BCM8512 is an 10 Gigabit DWDM transport processor that supports all the major functions on a DWDM line card:

• G.709 digital wrapper (final draft)

• G.975 Reed-Solomon RS(255,239) FEC

• SONET/SDH Performance Monitor

• 10 Gigabit Ethernet performance monitor

• Integrated OC-192 transceiver

The BCM8512 can operate in bidirectional mode and perform SONET/

SDH or Ethernet performance monitoring in both the receive and transmit paths. All necessary performance monitor functions for

SONET/SDH and 10 Gigabit Ethernet are provided for operations, administration, maintenance, and provisioning (OAM&P) so that no external performance monitor is required.

The G.709 digital wrapper allows a multitude of signals to be carried over the optical transport network. These signals include legacy

SONET/SDH and PDH signals, along with packet-based data such as IP,

ATM, GbE and SDL.

The BCM8512 is the first digital wrapper, FEC and performance monitor chip with an integrated 10 Gigabit transceiver in the industry. The transceiver is programmable to support OC-192 SONET/SDH, LAN

PHY and WAN PHY rates with and without FEC. The transceiver performs the clock and data recovery (CDR) and demultiplexing functions on the serial input data and the clock multiplication (CMU) and multiplexing (MUX) functions to produce the serial output data.
