Hybrid Electro-optic ADC/DAC Module With Optical Interconnects

Objectives

The goal of this activity was to design, manufacture and demonstrate two hybrid devices encompassing: an ADC with an electro-optic transmitter and a DAC with an optoelectronic receiver both adapted to support Gbps fibre optic interconnects linking to a high throughput Digital Signal Processor on board telecommunications satellites.

Challenges

The key issue of this project is to develop two hybrid devices encompassing:

  1. State-of-the-art AD-Converter with an electro-optic transmitter,
  2. State-of-the-art DA-Converter with an optoelectronic receiver.

The main challenges were in the realisation of opto-electronic sub-assembles and combining them with a SERDES function realized using an FPGA circuit with output ports operating at 6.25 Gbps. The link contains 4 parallel channels and is redundant.

Plan

Specific tasks to be performed in this project are the following:

  • Review of requirements and architectural Trade-off,
  • Design, manufacture and testing of Hybrid ADC device,
  • Design, manufacture and testing of Hybrid DAC device.

Current Status

The project was completed at the end of June, 2012.
