First quarter shipment numbers are in, and the shift from BPON to GPON in fiber-to-the-home deployments is clear. While most 2007 shipments were BPON, in the first quarter of 2008, 90% of Motorola’s optical line terminals (OLTs) shipped were GPON. Top Motorola PON customers so far this year are Verizon and the aggregate of Motorola ILEC customers in North America.
Why GPON? Speeds with GPON increase to 2.5 Gbps downstream and 1.2 Gbps upstream. That’s gigabits, not megabits.
