Patent Number Title Of Patent Date Issued
8130782 Control system using a mini slot signal in a passive optical network March 6, 2012
A passive optical network including: a parent station OLT (optical line terminal); and a plurality of child stations ONU (optical network terminating unit), wherein the parent station and the plurality of child stations transmit an upstream frame and a downstream frame to each other,
7496294 Optical multi-branch communication system February 24, 2009
A primary station equipment unit transmits, to a secondary station equipment unit, a message transmission enable signal granting transmission of a PST message from the secondary station equipment unit, when a predetermined period of time defined for transmission elapses after the pri
7443874 Control system using a mini slot signal in a passive optical network October 28, 2008
According to an aspect of this invention, dynamic bandwidth assignment (DBA) can be performed without interrupting communication of a regular cell and interfering with communication between child stations. In a passive optical network including a parent station and a plurality of chi
7403518 Packet transmission system, packet transmission method, packet transmission program, and recordi July 22, 2008
An OLT 1 sequentially allocates transmission permission of a packet on an upstream transmission line to a plurality of ONUs 2 registered, and performs packet communication in a simplified method with control by using a first timer for detecting a packet signal and a second timer for
7039066 Dynamic bandwidth assignment system and dynamic bandwidth assignment method capable of reducing May 2, 2006
A dynamic bandwidth assignment system includes a network unit for carrying out cell slot assignment, and a network termination for transmitting cells to the network unit by means of cell slots assigned by the network unit. When the number of consecutive valid cells the network unit r
7020162 Optical distribution network system with large usable bandwidth for DBA March 28, 2006
An optical distribution network system includes an OLT; a plurality of ONUs; a first optical network and a second optical network, one of which connects the OLT with the plurality of ONUs; and a bandwidth controller. The bandwidth controller apportions the plurality of ONUs between the
