Yes, Verizon uses Passive Optical Network (PON) technology for its fiber network:
- NG-PON2
Verizon uses NG-PON2 for its next-generation fiber upgrades. NG-PON2 has four wavelengths, each operating at 10 Gbps, which can be combined to offer up to 40 Gbps. Verizon chose NG-PON2 because it simplifies the network, eases the upgrade path, and is scalable to at least 100 Gbps.
- B-PON
Verizon has been using broadband passive optical network (B-PON) technology since it began construction of its all-fiber network in 2004.
- FiOS
FiOS, which stands for Fiber-Optic Services, operates on a passive optical network (PON). FiOS transmits data using light through thin, flexible glass fibers.
