Openreach: Developer Guide
Cabling and ONT positioning
Issues with home wiring
• Connectorised fibre cable too short,
cut or damaged.
• Defective or damaged home wiring
creating a fault on the line.
• Extension sockets not connected to
Openreach ONT.
• Bending radii exceeded causing reduced
levels of service due to fibre being broken
or the bend was too tight.
• Incorrect cable type or wiring
configuration
Impact on delivery
• Inability for Openreach to provide service
and developer requirement to re-provide
connectorised fibre cable.
• Poor user experience for home purchaser
with possibility of Openreach charges if
called upon to rectify.
• Slower data download speeds
experienced.
• Limit duct runs to a depth of 350mm on
footway, 450mm on soft ground or 600mm
if shared carriageway surface at house end.
• The Openreach duct shall be no greater than
15mm from the finished wall surface.
• The duct shall protrude no more 50mm from
the finished ground level.
• A draw rope must be installed between the
joint box and the duct at the property wall.
• The duct opening must be covered,
preventing the ingress of debris.
• Ducting from property to the footway boxes
shall be laid 4-6 weeks before the plots are
handed over.
Fixing cables securely
If you’re running any cables through a fire protected
area like a fire escape route, escape staircase or
walkway, the cable must be adequately secured
using
non-combustible
fixings. Wiring regulations
must be followed, ensuring that wiring systems
in escape routes are supported in such a way that
they will not be liable to premature collapse in
the event of fire. This applies to all cabling and
not just electrical cables e.g. alarm, telecoms and
control wiring. From January 2019 this will apply
throughout the installation
as the 18th Edition
wiring regulations come into force.
Typical issues with duct
presentation
• Duct not cut to the appropriate height
from the finished ground level.
• Duct installed too shallow.
• Duct protruding too far from the finished
wall surface.
• Duct not lining up with internal fibre
cable lead in.
Impact on delivery of issues
• Delay in completion – Openreach may refuse
to cable if we can’t guarantee adequate
protection.
• The capping and covers would look unsightly.
• Failure to provide conduit can prevent a cable
from being installed.
• Customers may not be able to place orders
and remedial work may incur additional costs.
