ASTRON Tx/Rx

ASTRON project aims at the design and development of an integrated optical transceiver (Tx/Rx) that will enable the wide and cost-efficient deployment of flexible core and access networks. The main features of the Tx/Rx will be the followings:

• Reconfigurable bandwidth allocation using either Optical OFDM or Nyquist WDM topology.

• Programmable modulation formats (BPSK, QPSK, 16-QAM)

• Programmable data rate Programmable FEC (offering tunability of the ratio of the actual payload to the FEC)

• Energy-efficiency by incorporating state-of-art digital, analog, mixed-signal and optical components into an integrated platform.

• Design for manufacturability using components that can be easily produced at low cost embedded into a compatible package.

The implementation of such a system and its use in the existing core networks will provide a low-power and low-cost alternative to the use of expensive and power hungry transceivers made from discrete components. The transmitter and receiver modules will be packaged into a small form factor module in order to be compatible with the current network devices.
