1. Yes, I will try to avoid SFP+ to RJ45 modules as much as possible but still can not run away as of now if I go for the 3Gbps/5Gbps plans (not interested in 10Gbps plans now), the only chance to toally avoid SFP+ copper module is to use VQ XGS-PON ONU option -- but I am reluctant to use VQ myself.
Just ordered one Hasivo switch to reduce one SFP+ copper module (about RMB399 plus GST and shipment).
2. Intended minimum setup -- need one SFP+ to RJ45 module.
XGS-PON ONT or bridged XGS-PON ONR -- Miniroute R1 N100 SFP+ port
with SFP+ copper module running PVE/pfSense (probably need a fan here)
Miniroute R1 N100 SFP+ port --
DAC cable -- Hasivo 2.5G switch 10G SFP+ uplink
Hasivo 2.5G switch 10GBASE-T port -- Laptop/Mac Mini M1 with USB 4 10G NIC for speedtest (LOL)
Miniroute R1 N100 2.5G port or Hasivo 2.5G switch 2.5G ports -- 2.5G mini PCs and 2.5G wireless AP
3. If using VQ XGS-PON ONU option, assume that it works with Miniroute R1 (Intel 82599ES based SFP+ ports), then yes I can avoid SFP+ copper module.
VQ Huawei XGS-PON ONU -- > Miniroute R1 N100 SFP+ port, running PVE/pfSense (probably need a fan here)
Miniroute R1 N100 SFP+ port -- DAC cable -- Hasivo 2.5G switch 10G SFP+ uplink
Hasivo 2.5G switch 10GBASE-T port -- Laptop/Mac Mini M1 with USB 4 10G NIC for speedtest (LOL)
Miniroute R1 N100 2.5G ports or Hasivo 2.5G switch 2.5G ports -- 2.5G mini PCs and 2.5G wireless AP
