Link utilization and comparison of EPON and GPON access network cost

Optical transmission is getting more popular in the access network due to the increasing demand for bandwidth. The most advertised transport solutions for the optical access are Ethernet based PON (EPON) and gigabit-capable PON (GPON), and the problem is which one to choose when establishing a new access network. This paper studies the network cost of EPON and GPON and bases the comparison on the link utilization.
