The 10G-EPON OLT and ONU LSIs for the coexistence of 10G-EPON and GE-PON toward the next FTTH era

10G-EPON OLT and ONU LSIs with parallel 10- and 1-Gb/s datapaths with a partly-shared-block architecture for full-wire rate throughput and the coexistence of 10G-EPON and GE-PON were developed for the first time in 40-nm CMOS. The full-wire rate throughput without a frame loss and a table look-up in a minimum frame interval are achieved for 10- and 1-Gb/s frames simultaneously.
