FTTP (fibre to the premises) is fastest and most stable — fibre runs directly into your unit. FTTB (fibre to the building) brings fibre to the building's communications room, then uses the building's internal copper or coax to your apartment — speed depends on that internal wiring, which is why apartment speeds vary so much block to block. HFC reuses the old pay-TV coaxial cable network — generally solid but can slow during peak evening hours in dense areas. FTTN (fibre to the node) is the oldest and most distance-sensitive: the further your home is from the street cabinet, the slower it gets. Inner Sydney apartments are mostly FTTP, FTTB or HFC; FTTN shows up more in older suburban houses.

FTTP(光纤到户)最快最稳，光纤直接接到你的单元。FTTB(光纤到楼)把光纤接到大楼通信间，再用楼内已有的铜线或同轴电缆接到你家——速度取决于这段楼内布线质量，这就是为什么同一栋楼不同单元网速差异很大。HFC沿用了原来的收费电视同轴网络，总体稳定，但在高密度地区晚高峰可能变慢。FTTN(光纤到节点)是最老的一种，离街边机箱越远速度衰减越明显。悉尼内城公寓大多是FTTP/FTTB/HFC；FTTN更多出现在较老的独立屋郊区。
