Verizon is hoping that bringing channel bonding to NG-PON2 will finally allow it to increase bandwidth on an access fiber network without also changing out the equipment that sits in the field.Vincent O’Byrne, director of access technology at Verizon Communications Inc. (NYSE: VZ), tells Light Reading today in an interview, that his company is trying to learn from the painful experiences of moving from broadband passive optical networks (BPON) to gigabit PONs (GPON) and now to next-generation PON (NG-PON2), and having in each instance to either replace existing optical line terminals in the outside plant or deploy new equipment adjacent to those boxes in order to boost bandwidth.
