What is BPON

 

BPON: Broadband Passive Optical Network

FiOS networks are built upon Passive Optical Networks. BPON meets a standard which includes 622 Mbps download speed with 155 Mbps upload speed. Verizon typically splits a BPON fiber to 32 nodes, each simultaneously capable of 20 Mbps down and 5 Mbps up.

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

BPON
BPON (Broadband PON) is a standard based on APON. It adds support for WDM, dynamic and higher upstream bandwidth allocation, and survivability. It also created a standard management interface, called OMCI, between the OLT and ONU/ONT, enabling mixed-vendor networks.

GPON
GPON (Gigabit PON) is an evolution of the BPON standard. It supports higher rates, enhanced security, and choice of Layer 2 protocol (ATM, GEM, Ethernet). In early 2008, Verizon having installed over 800 thousand lines by mid year. British Telecom, mobily-saudiarabia, Etisalat-uae, and AT&T are in advanced trials.
