LEAD-IN CABLE
INSTALLATION SYDNEY

A lead-in cable is the cable that connects the telecommunications network in the street to your property. Depending on the property and network type, it may run underground via conduit from a pit, aerially from a network pole, or through a private pole before reaching the building.

For copper-based services, the lead-in is typically a two-pair copper cable. For HFC services, it must be RG6 quad shielded coaxial cable to meet the minimum specification. In larger sites — such as industrial estates and multi-building complexes — heavier-grade external cabling may be routed between pits and buildings.

The lead-in cable is the critical link between the street network and your property. If it is damaged, undersized, or non-compliant, your service will not activate correctly regardless of what happens inside the building.

NBN Co owns and maintains the network infrastructure up to their network boundary — typically the network pole in the street or the pit at the property boundary. Once the cable crosses onto private property, maintenance and replacement responsibility generally falls to the property owner.

This means if your lead-in cable is damaged, corroded, water-saturated, or simply no longer compliant, NBN will not replace it. It is a property owner responsibility. SECURE A COM installs and replaces lead-in cables on residential, commercial, and industrial properties across Sydney.

For occupational health and safety (OH&S) reasons, NBN contractors are not permitted to climb private steel poles. This is a documented policy, not a case-by-case decision. If your property has a private steel pole, NBN will not perform the aerial lead-in installation beyond their network boundary — regardless of how long you wait or how many appointments are booked.

SECURE A COM fills this gap. We install a compliant point of attachment on your building, mount an approved pole hook on the private steel pole, and run the aerial lead-in cable between them. We then leave sufficient compliant cable coiled and prepared on the pole so NBN can simply attend and complete their final connection across to their network pole.

This is one of the most common scenarios we resolve — and without a licensed contractor filling this role, properties with private poles can remain unconnected indefinitely.

A point of attachment (POA) is the approved hardware mounted on your building that anchors and supports the aerial lead-in cable as it enters the property. It provides the structural anchor point for the cable span between the pole and the building, and it is where the lead-in cable is transitioned from external aerial to internal building entry.

NBN requires a compliant point of attachment before they can connect the aerial cable from their network pole. If the POA is missing, incorrectly installed, or non-compliant, NBN cannot complete the connection. We install compliant POAs as a standard component of every aerial lead-in installation.

For copper lead-in installations, we use two-pair copper gel-filled lead-in cable. Gel-filled construction means the cable core is filled with a water-blocking gel compound, making it:

Waterproof — resists moisture ingress even in flooded conduit. UV-resistant — safe for direct aerial runs exposed to Australian sun. Insect and rodent resistant — the gel and jacketing deter pest penetration. Heavy-duty jacketed — provides mechanical protection for both underground and aerial external applications.

This cable type is suitable for both underground conduit installations and aerial runs. It meets the requirements for external lead-in cable work and is the correct specification for new copper lead-in builds and replacements.

HFC lead-in installations require RG6 quad shielded coaxial cable. Quad shielding means the cable has four layers of shielding — two foil layers and two braid layers — providing maximum protection against signal interference and ingress from external RF sources.

Standard RG6 (dual shielded) or lower-grade coaxial cable will not meet the HFC network specification. Using non-compliant cable for an HFC lead-in will result in signal degradation, noise ingress, and activation failures — NBN's HFC network is sensitive to signal quality at the lead-in level.

We install only compliant RG6 quad shielded cabling for all HFC lead-in work. If your existing HFC lead-in is lower grade and causing activation or performance issues, replacement with quad shielded cable is the correct fix.

In most cases, yes. Aerial lead-in replacement typically requires no excavation — we remove the damaged cable and run a new compliant cable between the pole and the building's point of attachment. The disruption is minimal and usually completed within a single visit.

Underground lead-in replacement depends on the condition of the existing conduit. If the conduit is intact, the cable can often be pulled through the existing path. If the conduit is collapsed, blocked, or absent, new conduit installation will be required. We inspect and assess the conduit pathway during our site evaluation and quote accordingly — no surprises after work begins.

A lead-in cable is the external cable that runs from the street network — either from a pit or a pole — to your property. It is outdoor-rated, heavy-duty, and must meet specific external-grade specifications for mechanical protection, UV resistance, and moisture resistance.

Internal NBN cabling is everything from the building entry point onwards — cable runs inside wall cavities, to network termination points, wall sockets, and communications outlets. Internal cabling is a separate scope, uses different cable grades, and is governed by different installation standards.

SECURE A COM handles both. Lead-in cable work is an external-only scope — from the network boundary to the building entry. If you also need internal cabling or wall socket installation after the lead-in is in place, this is quoted as a separate service.
