What is Optus VDSL FTTN?

Optus VDSL2 type service is a technology used within the NBN, and depending on your area, you might be connecting using VDSL2 instead of FTTH. Technically, think of a VDSL type connections as a glorified ADSL2+ connection, however deliverying higher speeds. It still uses the same copper wiring from the NODE to your house, so nothing needs to be upgraded internally.

A significant difference however, is that the NODE for VDSL2 needs to be considerably closer in terms of distance than traditional ADSL services. Traditionally Optus, or in-fact or any ISP, housed their DSLAM equipment in Telstra Exchanges, meaning you could achieve high speed internet connections roughly up to 5km distance away from the exchange.

With VDSL connections, you are able to achieve higher speeds of up to 100Mbps and even higher, but that depends and certain factors such as distance, attenuation, signal power, and the VDSL profile Optus has set. From memory, Optus uses profile 17a for VDSL2 service delivery.

VDSL2 also connects the same way, using either PPPOA, or PPPOE authentication methods on your home modem.
