GPON vs. GEPON

[nanog-isp at mail.com (nanog-isp at mail.com)]

Hello all,

For those of you with optical last mile networks that are familiar with both GPON and GEPON, would you mind sharing experiences of the differences between GPON and GEPON, especially from an operative perspective?

For arguments sake let's assume bitrate, split ratio, cross vendor compatibility and purchase price differences aren't of major interest. 

Thanks,

Jared
