This standard provides the minimum installation and
operational requirements for Murdoch
University cabling
systems.
This standard applies to all ICT cabling (voice, data, audio
and visual cabling), in horizontal cabling, backbone cabling, and
inter-building cabling. The standard is to be applied to all copper
and fibre optical cabling within all Murdoch
University campuses and
buildings, regardless of their intended use.
The principles of the standard must be applied when
conducting cabling projects for:
- The
construction of new buildings;
- Fit
outs of existing buildings;
- Upgrades
to existing cabling infrastructure;
- Implementation
of cabling infrastructure to interconnect new or existing buildings.
Refer to appendices for more details.
Ensure effective and consistent management of cabling
throughout all Murdoch
University campuses and
buildings.
Must ensure that:
- All
cabling work conducted is consistent with regulatory and legislative
obligations including relevant Australian and Western Australian
Standards;
- All
relevant stakeholders are consulted prior to commencing cabling projects;
- Comprehensive
audits are conducted on completion of cabling projects;
- Only
cabling systems offering appropriate warranties are used;
- Warranty
documentation for cabling infrastructure is kept up to date and that
copies are provided to the Office of IT Services.
Any conflicting information should be clarified with ITS.
Any conflicting information should be governed by reference to the following documents:
- Relevant
Australian Standard;
- Relevant
International Standards;
- This
reticulation standard;
- Internal
Instructions by ITS.
Ensure requests and purchases comply with Australian and Murdoch University standards.
Must ensure that:
- Where
cabling is purchased as part of a major building project contracts between
Murdoch University and the
contractor/vendor are formed in compliance with AS4000 or AS2124;
- This
standard is referenced as requirements in tender and contract
documentation;
- Tenders
and contracts for ICT cabling are issued separately from any other
electrical or building works;
- All
ICT Installers must be registered by one of the Australian Communications
Authority (ACA) approved registrars;
- All
ICT installers have been inducted by the Office of Commercial Services
(OCS).
- All
ICT installers must be selected in consultation with ITS
Ensure that all installations meet the following specifications:
- Adhere
to a single certified system throughout a new building installation;
- Undergo
certification tests prior to acceptance of work completed;
- Provide
copies of certification tests to the Office of IT Services;
- Comply
with the installation specifications detailed in this standard.

General Installation Notes
5.2 Horizontal
Cabling Installation Requirements
The required performance level for horizontal cabling is
Class E permanent link, or channel, utilising Category 6 cable and connecting
hardware. This is the general requirement unless compelling reasons exist to
use a lower performing category of cable and connecting hardware
- Compliance
testing for Class E installations requires a Level III tester as defined
by the Standards Australia AS/NZS 3087.
- All
certification documents must be lodged with ITS
before outlets can be officially approved for operation.

cable pathway shall not exceed an overall length of 90 metres.
- Cable
terminations will be made at Cat6 compliant High Density (32 port) patch
panels, fitted in a rack of appropriate size for the building.
- A
cable management panel shall be fitted between each patch panel.

conduits and ducts for building wiring shall be installed so that cabling
is not exposed to moisture.
- Where
multiple outlets are installed in a single room the minimum conduit size
is 25mm per 6 x CAT6 outlets.
- Where
ceiling spaces will not be available to provide future cable
installations, spare conduits shall be installed. 1 x 25mm spare conduit
shall be installed for every 2 offices.
Floor chases may be used where required.
- Minimum
installation is 2 x 25mm conduits.
- 1 x
25mm conduit shall be installed for every 6 x CAT6 cables required.

wall plug numbering scheme is defined, managed and assigned by ITS.
- The
contractor shall obtain the above information from ITS
at the time of installation.
- Unless
otherwise specified by ITS, new outlets will be installed at a convenient
point, adjacent to telephone and power services.
Some specialist applications may benefit from having fibre
optic cable installed as the horizontal cable.
- Support
for such applications will be handled on an individual basis with direct
consultation with ITS.
Backbone cabling shall be considered as any cabling that
interconnects campus building ICT services together.
- All
backbone cabling for all data services shall be comprised of fibre optic
cabling.
- Copper
cabling may be used in special circumstances. Earthing and surge
protection shall be used for these circumstances.
- Subject
to application, cabling for Telephone services may either be multi-core
copper cabling, or optical fibre cabling, as advised by ITS.

pits should be established at locations no greater than 70 metres apart or
at any point where there is a change in direction.
- Wherever
possible communications pits must be aligned so that they are easily
located

pits should be located such that they remain permanently unobstructed (by
landscaping, flowerbeds etc).
- All
backbone pathways shall be connected by 3 x 50mm conduits.
- All
major backbone pathways shall be connected by 3 x 100mm conduits.
This is pathway
between the backbone’s entrance point into the building and the entrance room.
Appropriate external conduits must be provided so that the
proposed building can be connected back to the to the existing campus network
infrastructure.
- The
building entrance rooms should be connected to the external data pit via 3

facilities shall be used for ICT services only.
Where computer conduits cross open ground, approved external
grade single mode or multimode fibre shall be used.
- To
minimise the possibility of damage due to mechanical stress on the cable,
wherever possible fibres shall be reticulated in their own conduit and not
with other building services.
- Each
fibre shall be tagged at each terminating fibre patch panel, and at every communications
pit along the way.
- Tags
shall be made of durable material to resist weathering.
- The
use of blow tubes is the recommendation for connecting all major
buildings.
- 12-core
Single-mode fibre cable is the minimum recommended fibre capacity to all
major buildings.
Where conduits do not traverse open ground and therefore
moisture is not a problem
- Suitable
loose sheath single mode multi-core fibre of the "external light duty
loose tube riser fibre" will be used.
- Where
internal fibre is used to inter-connect groups of data enclosures, the
fibre must be housed in physically continuous conduit.
Each fibre shall be clearly tagged with a unique
identification number
- The
fibre numbering scheme is managed by ITS.

approved enclosures are used to house the fibre and termination, panels on
the enclosure should be such that they are easily removed for inspection
and maintenance of the fibre.
- All
fibre patch panels shall be enclosed in a sliding tray or removed front
panel, such that fibre outlets are not visible.
Fibre loss and fibre transmission characteristics should
conform to the appropriate Australian standards.
New fibres will not be put into operation until the
appropriate certification documentation has been lodged and approved by ITS.
As specified in
standard AS/NZS 3084:2003. Refer to this standard for additional details and
definitions as required.
