GPON is built on newer technology and is similar to BPON except that throughput speeds are higher. A 2.488 Gbps download speed coupled with a 622 Mbps upload speed, typically split to 32 nodes yields about 80 Mbps down and 20 Mbps up.

Verizon is building new networks with GPON technology, while existing BPON systems will only be upgraded when capacity limits are reached.
