FTTN NBN Roll Out Internet Hardware
- What are the specifications for a Fibre To the Node (FTTN) NBN connection to the premises?
- What hardware specifications influence NBN use?
VDSL2 Network Termination Device NTU
Very-high-bit-rate digital subscriber line 2 (VDSL2)
This is a copper transceiver that is used in the premesis to convert VDSL2 traffic into Ethernet networking services.
Sample VDSL2 NTU Specifications
- Up to 30 MHz signal on copper pairs.
- Up to 100 Mbps in speed for short distances.
- You have to purchase a VDSL2 compatible router. ($100-$200)
- RJ45 Ethernet sockets available for networking.
- Wifi available for wireless devices in premises.
FTTN (Fibre to the Node) Advantages and Disadvantages
|Less civil works required||Copper pair quality unknown|
|Quicker to deploy||Final speed available is variable|
|Less initial capital costs||10,000's FTTN cabinets required in suburbs|
|FTTN cabinets all dependant on mains power $$$|
|VDSL2 speed falls with distance in 100's of metres|
|Spare capacity is dependant on available good copper pairs|
|VDSL2 is at a higher untested frequency compared to ADSL|
|VDSL2 speed is subject to speed reduction in heavy rain|
|VDSL2 speed is subject to speed reduction with crosstalk interference|
|VDSL2 speed standard assume 0.4 mm minimum copper pair cables|
|Copper pair to premises connectors will reduce Internet speed|
|Copper pair to premises twisted paths can reduce Internet speed|
|Copper pair mainenance costs are higher than all fibre|
|VDSL2 upload speed is not guranteed which limits business uses|
|VDSL2 can use 2 copper pairs for some more speed if pairs available (not planned)|
|VDSL2 cannot scale up to 1Gbps like FTTP fibre|
