  • How to tell if a device box contains EPN or GPON

    How to tell if a device box contains EPN or GPON

    GPON and EPON devices are not interchangeable. Look for model numbers and specifications on the equipment. Manufacturers typically label their products clearly, indicating whether they are GPON or EPON. When tasked with identifying whether a network is using GPON or EPON, there are several practical steps and considerations: Optical Line Terminals (OLTs) and Optical Network Units (ONUs) or Optical Network Terminals (ONTs) are specific to the type of PON. An easy way to tell is if you can order 2 or 5 Gbps service, then you are most likely already on XGPON *if you are getting faster on GPON then it may be local bandwidth management policy. This document is not restricted to specific software and hardware versions. The information in this document was created from the devices in a.
