Telco Conduit Bends, Fittings and Pit Assemblies
The communications range includes NBN Co and Telco/Telstra bends from DN20 to DN100, straight and slip couplings, reducing couplings, bushes, caps, plugs, and the full set of Telstra P1 - P9 pit assemblies. Bend configurations vary by radius, degree and end type (FF or MF).
The complete schedule - every bend radius, fitting and pit assembly with product codes - is set out in the technical guide.

Iplex has supplied conduit to Australian communications networks for decades, through the Telstra copper era, the NBN rollout, and the current shift to full fibre. As carriers extend FTTP, upgrade fixed wireless, and build backhaul for mobile and data-centre capacity, the volume of underground duct going into the ground keeps rising. Conduit is the part of that network that has to last longest: cables get replaced, the duct stays.
The range reflects how communications duct is actually installed. White PVC conduit to AUSTEL TS009 covers most pit-and-pipe work from DN20 to DN100. Heavy-duty white PVC handles deeper cover and road crossings up to DN150.
Where open trenching isn't an option, under roads, rail and waterways, PE100 conduit is made for horizontal directional drilling, with a stated maximum pulling force for each size so the design engineer can check haul lengths. HDPE subduct lets installers run several fibre cables inside a single larger duct and keep spare ways for future work.
State requirements differ, Queensland and Victoria each specify their own heavy-duty white conduit. Iplex’s range of telco conduits, couplings and bends accounts for that, with suitable options for application in any state.
With NBN Co and Telstra bends, couplings and pit assemblies in the range too, a specifier can detail a whole route from one manufacturer, with product codes and dimensions that match the drawings.
For network builders, civil contractors and specifiers, that single-source coverage matters on a program of works: consistent product codes, dimensions that match the drawings, and Australian manufacturing behind the supply.

FAQs
Which conduit is used for NBN installation?
NBN network conduit is white. Iplex supplies NBN Co-compliant bends in DN20, DN50 and DN100 as part of its white PVC communications range, with DN20 used for lead-in and smaller runs and DN50 and DN100 for larger network routes.
The correct size and product for a specific job is governed by the current NBN Co specification, so confirm the requirement against that spec or contact Iplex before ordering.
What size communications conduit is used in Australian telecommunications networks?
Common sizes run from DN20 for lead-in and small distribution up to DN100 and DN150 for main routes and heavy-duty applications. Iplex supplies white PVC communications conduit in DN20, 25, 32, 50, 80, 100 and 150.
What is the difference between white and orange conduit?
White conduit is used for communications and telecommunications cabling. Orange conduit is used for electrical power. Keeping the colours separate lets installers and future works identify what a duct carries.
What is AUSTEL TS009?
It is the specification Iplex's white PVC communications conduit is manufactured to. Product codes and dimensions for the TS009 range are listed in the table above.
Can PE100 conduit be used for fibre optic installations?
Yes. Iplex PE100 communications conduit is made for trenchless installation such as horizontal directional drilling, and HDPE subduct is used to bundle and protect fibre cables inside larger ducts. Each PE100 size lists a maximum pulling force to help with haul-length design.
