Chuck, I have heard that BPON is on its way out. You are using GPON? How long have you had it in place? Is this done with passive optical splits 1 by 32? Is it Wave Division Splits? If so how many splits per node? Still 20km distance by design? I thought there were problems with GPON not working in 1 by 32? This is very new to me so forgive newbie questions. If you have a link to an easy to digest primer on GPON for newbies like me I would appreciate it. I know fiber is not really a wireless issue itself but I am planning to start building my own fiber backhauls to my wireless towers and inter-connecting with enterprise customers along the way using my fiber. I think this discussion is relevant here. Scriv
