Fujitsu Releases Compact GPON Transceivers

Fujitsu introduced the first optical transceiver compliant with ITU-T G.984.2 Class C and Class C+ for Gigabit Passive Optical Networks (GPON). Existing devices only comply with the ITU-T(2) G.984.2 Class B+ specification. Fujitsu will begin selling optical transceivers compliant with Class C at the end of January 2009 and with Class C+ at the end of April 2009.


Fujitsu said its GPON design has improved optical output and receiver sensitivity, allowing for the use of a greater number of optical branches (64 or more) and loss reduction lines for optical-fiber channels, as well as increasing the distance between subscriber premises (40 km or more) by developing the following technologies:

  • Burst-mode receiver technology that can receive faint burst-mode signals (discontinued optical signals with different times) consuming half the power or less, when compared to existing Class B+ compliant transceivers.


  • A highly efficient thermal dissipation structure and control software to ensure stable operation of optical devices across a wide temperature range, enabling 150% more power output when compared to existing Class B+ transceivers.
