Optical Transceiver (10 Gbps)


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.


  • 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



A digital control system and transceiver control firmware embedded in a Microcontroller were produced and delivered to a customer. Circuits with Microwave drivers and amplifiers were implemented. Customer used the solution to deliver 45 different SKUs of reference designs customized to the requirements of numerous network companies.
