A 2.5G/10G co-existing OFDMA-PON is demonstrated through 20km SSMF with 31dB loss budget. Only one receiver at the OLT and low-speed transceiver at the 2.5G ONUs are required, thereby reducing system complexity and cost.
A low-cost optical subassembly design for large core fiber transceiver is presented. The complete transceiver module is realized by assembling the low-cost optical subassembly directly on the transceiver functional printed circuit board. -7 dBm optical power output and 6 dB extinction ratio are achieved on transmitter by the vertical self-alignment and horizontal passive alignment at the transmitter...
