ABSTRACT:
An OLT1sequentially allocates transmission permission of a packet on an upstream transmission line to a plurality of ONUs2registered, 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 controlling transmission permission time, in order to transmit an IP packet of variable length without mounting a function of complex processing for analyzing an upstream packet in the OLT1.
