Hi all, Looking for some advice/recommendations. We’re looking to select a GPON/VDSL/ADSL vendor for a number of new greenfield and brownfield deployments and have been considering the big 3 - ALU, Huawei and Calix. In PON land we would be delivering an “RSP” style service where each port, or a VLAN on a port can be sold to a different RSP to deliver services on. We are also delivering RF and POTS services via these units. So far we’ve found most them to be largely feature comparable and stable in terms of implementation and support. Each vendor has been keen to engage with us and work to make us as comfortable as possible with their product set. The only major differentiator on a hardware level is we’ve noted that the newer ALU chassis do not support xDSL cards, and so we would be stuck on the previous generation of chassis if we wanted to retain xDSL support, where Huawei and Calix don’t have this limitation. We do like Calix’s general view towards software programability and what they are talking about in terms of the future of SDN based networking. That said, there seems to be a number of pro’s/con’s with respect to each vendor in their own ways. Does any one have any strong opinions or recommendations why one vendor is better than another? Equally, does anyone have any brilliant success stories with any of the vendors or horror stay-away stories that we should know? -- Regards, Mark L. Tees
