Wiring for broadband

Home wiring is one of the leading issues impacting on the performance of our existing copper-based broadband services. If you're building a new home or rewiring an existing home, chat to your electrician to make sure you get the best possible outcome. 

Wiring your home for broadband

Are you building or renovating?

Home wiring is the most common cause of poor broadband services. If you are building or renovating ensure that you can access the best possible broadband services over our new fibre or existing copper networks by specifying ‘star configuration’ wiring and quality cabling – talk to your architect or electrician early.

Who does the work?

  • Your electrician can work with you to design a wiring plan to meet your needs. As home wiring requirements become more complex, you can also choose to use a specialist cabling company.

  • If you are laying a driveway you and your builder or electrician need to ensure green telecommunications pipe is laid from the property boundary to the external termination point at the house. You can find more information on the lead-in pipe in the Contractors section.

  • Many home security systems are dependent of a copper line. If you are connecting to our fibre network ensure that the security company is aware that you will need a system that will work with fibre.

Three things to keep in mind

Whether you are connecting to our existing copper network or our new fibre network the recommendations are the same.

When you are building or renovating your home it is the ideal time to ensure that you are future proofing to deliver the best broadband experience. 

Three important things to consider:

  • Use Cat6 cabling
  • We recommend star wiring configuration
  • Treat jackpoints like you do electrical outlets - you can never have enough of them

Cat6 cabling 

Future proof your home by installing Cat6 wiring which can carry up to 10 gigabit broadband

Although Cat5 cabling may be able to deliver your current needs it isn't designed to handle the capacity that can be delivered by our new fibre network. It can handle 100 Mbps speeds. 

Cat5e is designed to reduce interference between different circuits and channels and can handle speeds of up to 1000 Mbps. Keep in mind that we have just launched a 1 Gig broadband service in Dunedin.

Cat6 is suitable for up to 10 gigabit broadband and has enhanced features that reduce interference further. 

Star wiring 

We recommend star wiring configuration.

Re-wiring existing home

Where you are rewiring an existing home we recommend the use of a composite cable:

Jackpoints 

Treat jackpoints the same as you do with electrical outlets. You can never have too many. We are connecting more and more devices to the internet and you shouldn't underestimate the need for jackpoints in most rooms. We recommend RJ45 jackpoints.

For many homes the focus for delivering fibre will be in the living room near the TV. Don't forgot about smart TVs that may be installed in second living areas, bedrooms or kitchens. Will one the bedrooms become a home office?

We suggest:

  • At least two RJ45 type jackpoints with two ‘F’ co-axial outlets  on the same faceplate in each bedroom and normally occupied room. Don't install any in wet areas such as bathrooms and laundries. Two or more such outlets are recommended in the lounge, family room room and study/home office.
  • However, four ‘F’ co-axial and four RJ45 jackpoints should be installed at the main TV position.
  • At the home distributor box the Cat6 cables should ideally be terminated on RJ45 jackpoints type modular sockets mounted in a patch panel. 

Other telecommunications equipment requirements 

Who supplies what equipment:

  • You, your builder or electrician need to supply the home distributor box, RJ45 jackpoints and the cable. If you are laying a driveway you and your builder also need to ensure green telecommunications pipe is laid from the property boundary to the external termination point at the house.

  • We supply the Optical Network Terminator (ONT) which connects your property to our network. When it is installed it still belongs to us so if you move you need to leave it in the house for the next occupents to use. We will install this in the home distributor box.

  • Your broadband provider may supply a modem or router - or you can provide one yourself. This may also supply WiFi as well. the residential gateway (RGW). Chorus’ optical network terminal (ONT) will be installed in the home distributor box when the fibre service is installed.
" If you have any problems, call 0800 MYFIBRE (0800 693 427). "

Testing and verifying is critical 

Poorly installed wiring can affect the quality of the phone or broadband services.

As a homeowner you should expect a detailed report showing the level of services supported by your home wiring.

We strongly recommend that newly installed cabling is tested and verified by the installer as being able to operate at the speed it is rated for.

The performance of communications cabling can be affected if:

  • Too much cable insulation is removed
  • The communications cabling is too close to electrical cabling, causing interference
  • The correct bend radius is exceeded
  • Wiring is incorrectly terminated
  • Copper pairs are not kept twisted as close as possible to the point of termination
  • Poor quality components (e.g. patch cords and connectors) are used

Wiring homes for broadband

Are you wiring a new home or rewiring an existing property?

Ensure you deliver home wiring that makes the most of the new ultra-fast broadband network for your clients. Poor home wiring is one of the leading factors impacting on broadband performance. Cat6 cabling installed in a star wiring configuration is ideal.

Cable Installation Requirements 

To ensure availability of services throughout your client's home, these minimum standards have been developed by the industry though the Telecommunication Carriers Forum:

  • Cabling must be ‘star configuration
  • A star wiring (home distributor) box needs to be located at the ‘star point’ to provide cross-connect and testing facilities
  • This star point must be internal, accessible and ideally located just above the External Termination Point (ETP) position. The star point will typically be set into the side wall of a utility room or garage.
  • The home distributor box must be large enough to house devices such as a router and video splitter. It must also have integrated power sockets for these devices
  • Cables to be a minimum specification of Cat6 (UTP) and Tri-Shield RG6 Coax
  • Run two Cat6 cables and two RG6 from the home distributor to each outlet position
  • Run four Cat6 cables and four RG6 from the home distributor to the main TV position
  • Leave at least 300mm of cable slack at each outlet
  • Run at least one Cat6 cable plus one 20mm duct from the home distributor box to the ETP. Leave at least 500mm of cable slack at the ETP
  • Cable through the wall at the ETP must be protected within a short length of plastic pipe
  • Make sure all clearances between communication cables and power cables are maintained. See the TCF Premises Wiring Code of Practice for more detail on the segregation of services.

Cat6 cabling is recommended to future proof the building.

Although Cat5 standard wiring may be sufficient to meet the bandwidth demands of current telecommunications services,  but we now recommend Cat6 cabling to future proof the building, or consider installing cabling in ducting – refer to the TCF ‘Premises Wiring Code of Practice’ for more information.


Star wiring 

Star wiring is the preferred methodology to wiring homes to get the best experience on our UFB fibre network. It provides flexibility to the distribution of connectivity throughout the home.

We have developed some suggested approaches to home wiring based on standard house layouts.

The guide takes you through three options:

  • Optimal star wiring configuration
  • Star wiring with voice delivered via the RGW
  • Rewiring options for an existing home

You should be able to source OptiC@t hybrid cable from any electrical wholesale outlets such as Active Electrical, Cory's, Ideal, JA Russell Ltd, Radcliff Electrical, Redpaths or Scott Electrical.


Recommended outlets 

When you’re looking at where to install outlets or jackpoints in the new premises be sure to consider the following:

  • At least two RJ45 type jackpoints with two ‘F’ co-axial outlets for most outlets on the same faceplate in each bedroom and normally occupied room.
  • For the main TV position we recommend four RJ45 jackpoints and four ‘F’ co-axial. Avoid wet areas such as bathrooms and laundries.
  • Two or more such outlets are recommended in the lounge, rumpus room and study
  • At the home distributor box the Cat6 cables should ideally be terminated on RJ45 type modular sockets mounted in a patch panel. This will allow very simple patching to/from routers and easy replacement if one becomes faulty.

Setting up the home distributor box 

It is the homeowner’s or builder’s responsibility to supply the home distributor box, patch panel and patch cables.

The homeowner’s service provider will supply the residential gateway (RGW).

Chorus will provide the External Terminal Point and the Optical Network Terminal (ONT) which will be installed in the home distributor box at the same time.

 To set up a home distributor box:

  • The ETP position will typically be on the external wall of the garage or utility room in new homes
  • The ETP must be a minimum of 300mm above the final ground level and a maximum height of 1500mm.
  • Make sure a plastic pipe is installed through the wall at the ETP position and up into the star wiring box, using minimum 20mm diameter pipe and 300mm 90˚ bend. Do not use an elbow bend
  • Run the three Cat6 cables from the home distributor box to the ETP position
  • Leave at least 1000mm of slack loop at the home distributor box and at least 500mm slack at the ETP position
  • Install a dual power outlet in the bottom of the home distributor box to power the equipment
  • The home distributor box must be installed in the inside wall above the ETP position – about eye level is ideal
  • Home distributor box minimum dimensions are 350mm wide x 700mm high x 80mm deep.
  • The door on the home distributor box must have louvers so air can circulate to keep the equipment cool.

Testing and verifying is critical 

Poorly installed wiring can affect the quality of the phone or broadband services and homeowner experiences.

We strongly recommend that newly installed cabling is tested and verified by the installer as being able to operate at the speed it is rated for.

The performance of communications cabling can be affected if:

  • Too much cable insulation is removed
  • The communications cabling is too close to electrical cabling, causing interference
  • The correct bend radius is exceeded
  • Wiring is incorrectly terminated
  • Copper pairs are not kept twisted as close as possible to the point of termination
  • Poor quality components (e.g. patch cords and connectors) are used.

The homeowner should expect a detailed report showing the level of services supported by their home wiring.

Wiring your business for broadband

Identifying your requirements

Your cabling requirements are dependent on the size and complexity of your business. Smaller business should follow the wiring recommendations for residential properties. Larger businesses should contact a structured cable specialist to design and deliver a tailored solution.

Use Cat6 cabling to ensure your business wiring is future proofed.

The cabling requirements of your business will be dependent on:

  • Number of staff and what type of connectivity is required
  • How you deliver voice services
  • Data requirements

A well designed structured cable solution will take into account the technical requirements of the business and will include computer cabling, voice requirements, outlets, repairs, maintenance and fault finding.

Installation tends to be simplier than residential properties due to the nature of commercial buildings, with ceiling panels and a cable backbone part of many complexes.

Keep in mind that if you want to connect your business to our new Ultra-fast broadband network and you are in a multi-story building you will need consent from the building owner.


What happens when copper is required? 

Within a UFB fibre area there may be commercial requirement for copper to be deployed to a new building/development for a particular network service required by a business.

In these instances, we will evaluate the deployment of copper  on a case-by-case basis, taking into account the particular business need.  We believe that the demand for copper network will decline over time as telecommunications service provider offer more sophisticated services over our new fibre network.

If you do require copper we will put together a specific network design and a quote on the costs of the specific lead-in and cabling requirements. We can undertake this work for you.
