Document Type and Number:
WIPO Patent Application WO/2010/092666
Kind Code:
A1
Abstract:
A high-speed optical signal control unit includes: a DBA scheduler unit (43) which outputs Report information on a child station device (ONU) of a 10G-PON system as Report information on the local device and allocates a grant allocated from a 1G-OLTMAC unit (6) to the ONU; a 10G control message termination unit (42) which outputs the ONU Report information to the DBA scheduler unit (43); a 10G control message generation unit (46) which outputs to the ONU, a Gate frame based on the grant allocated by the DBA scheduler unit (43); a 1G control message generation unit (44) which outputs a Report frame based on the Report information in the DBA scheduler unit (43), to the 1G-OLTMAC unit (6); and a 1G control message termination unit (45) which outputs Gate information in the 1G OLTMAC unit (6) to the DBA scheduler unit (43).
