Optical Transceiver (10 Gbps)

Introduction

This project consisted of a Microcontroller with embedded firmware used to control an optical transceiver and several Microwave driver and amplifier ICs. The customer was a semiconductor IC manufacturer.

Objectives

  • Control all functions of the transceiver.
  • Maintain stability over temperature of laser
  • Implement control system suitable for edge emitter lasers and VCSEL lasers
  • Manage receiver timing settings
  • Design suitable microwave circuits for electrical to optical interface
  • Implement XFP and SFP interface protocols substantially in firmware

Results
