INSTALLATION OF NEW CABLES IN OCCUPIED CONDUIT
/ DUCTS
1.
The conduit must be proven with a suitable mandrel prior to
attempting any hauling. As a guide where the conduit capacity is questionable
(e.g. the aggregated existing plus new cable/subduct diameters exceeds 80% of
the internal diameter of the conduit) the conduit must be proven with a suitable
mandrel 1.5 times the size of the cable. If this is successful and it can be
reasonably assumed there will be no damage to any cables, subducts or
infrastructure, the haul can proceed.
Conduit Proving
2.
If at any stage the proving of the conduit becomes difficult or the
conduit cannot be proven and there is a possibility of cable damage, the conduit
Conduit
Upgrading
MAIN ROADS Western Australia
Contract xxx/xx

must be upgraded
3.
Once all sections of the proposed haul have been proven the hauling
tensions and lay off points ,if required, shall be determined
4.
Pressure roping shall be used in preference to hand rodding, to
minimise the possibility of intertwining of cables during hauling.
5.
A water based cable lubricant that is Non-Toxic, Non-Flammable and
compatible with all types of cable sheath shall be used, on the cables, rope and
mandrel when hauling over existing cables.
Lay off Points

6.
Existing optical fibre cables shall be restrained from moving in the
same direction as the haul.
7.
During the haul supervision shall be provided at entry, exit and
change of direction locations.
705.28
HAULING – CARE OF EXISTING PLANT
1.
The existing MRWA TCS Network must be cared for at all times and
not interfered with during the course of proving conduits, the installation of rope
and/or additional cable.
Existing Network
2.
If the existing cables and/or closures need to be moved during work
tasks, they are to be handled carefully, suitably restrained and replaced correctly
in the pit on completion of the task.
3.
Avoid lacing the rope through existing cable loops, as this will cause
undue pressure to be inserted upon the cables and joints.
4.
Care must be taken to ensure existing cables, identification tags,
joints or other plant are not caught up with and dragged by the hauling rope or
cable being installed.
5.
Existing cables or subduct shall be constantly observed for
movement (through dragging). If there are any significant signs of cable
gathering, or of cable or subduct movement at any location along the route, the
haul shall stop immediately, and action taken e.g. reapply lubricants, restraint to
prevent further movement /dragging of the cable(s) or subduct, before
recommencing the haul.

OTDR LINK LOSS
1.
All OTDR Fibre test results shall be recorded and saved with the
correctly assigned MRWA Asset numbers used to describe End A / End B with
cursors correctly aligned.
OTDR Tests
2.
All fibres are to be tested utilising two-way OTDR Link Loss (LL)
measurements. The measurements shall also be carried out on spare fibres within
the cable that either terminate at one end only or are provided between
joint/splice locations.
Two-way
Measurement
3.
An OTDR Link Loss (LL) measurement shall be performed on all fibres
to confirm the integrity of the cable link excluding the performance of the preterminated connector.
Fibre Integrity
1. 4.
On terminated fibres the link loss tests shall be performed after
termination of connector, which would then include the connector loss being
factored in the LL data recording. The link loss shall be tested and recorded in
both directions at wavelengths 1550nm utilising the OTDR (Two-point method i.e.
position the first cursor just beyond the front end attenuation saturation dead
zone where the trace is linear and position the second cursor at the end of the
trace just before the trace begins to rise). The two-way (average) link loss (LL) for
a fibre shall be calculated as the average of the measurements. The two-way
(average) OTDR LL shall not exceed the following:
Link Loss Test
2. Maximum Loss at 1550 nm (LL) = 0.3L + 0.1N + 0.5, where:

b)
L = the optical link length in Km
c)
N = number of splices
5.
If a fibre fails the OTDR Link Loss after a number of remeasurements, then a more comprehensive evaluation of the fibre link should be
undertaken to determine the high loss i.e. re-check of any irregularities, splice
losses and fibre attenuation co-efficient (dB/km).
705.43
IRREGULARITY CHECK
1.
All fibres in each section length shall be checked for any irregularities
in both directions at wavelengths of 1310nm and 1550nm. The magnitude of
irregularities (point losses) in length shall be calculated as the average of the
irregularity loss measured in both directions at wavelengths of 1310nm and
1550nm. Irregularities shall not exceed 0.10dB (two way average) for any
wavelength.
2.
The magnitude and distance from each fibre end to an irregularity
shall be recorded on a fibre anomaly sheet to be included in the final report.
3.
Any point loss that exceeds the above criteria shall be rectified with
the fibre subsequently retested.

SPLICE LOSS / LOCATION
1.
These measurements shall be undertaken for the purpose of
ensuring the integrity and quality of splice performance and identifying and
documenting optical fibre cable distances to all splice locations to assist in the
future location of faults.
Splice Loss
2.
The optical distance and magnitude of all splices shall be measured
from both directions at wavelengths of 1310nm and 1550nm. The loss of any
splice shall not exceed 0.10dB (two way average) at 1310nm and 1550nm.
Test Wavelengths
3.
Any splice loss that exceeds the above criteria shall be re-spliced. If
the splice does not improve after two attempts at resplicing and OTDR testing
confirms that the splice loss is not consistent with a high point loss within the
splice enclosure then the splice shall be accepted but reported as a high splice
loss. All splice loss/joint measurements shall be recorded and any reported high
splice loss value shall be appropriately marked and reported.

This measurement shall be undertaken on terminated fibres to verify
the overall end-to-end power budget level of the entire fibre link. The Insertion
Loss (IL) for each fibre shall be measured in both directions using a stabilised
LSPM.
Insertion Loss
2.
These results shall be compared with predictions based on the
manufacturer’s SMOF geometrical properties and minimum splice loss criteria.
3.
The maximum two-way (average) Insertion Loss shall not exceed the
following criteria:
a)
Maximum Loss at 1310nm (IL) = 0.4L + 0.1N + 0.50C + 0.5
b)
Maximum Loss at 1550nm (IL) = 0.3L + 0.1N + 0.50C + 0.5

PRE-TERMINATED CONNECTOR LOSS
1.
This calculation is performed to verify the overall performance of the
individual connector / pigtail combination situated at either end of the optical
fibre link.
2.
For each fibre the delta between the maximum Insertion Loss
(average IL).
3.
LSPM Insertion Loss (Clause 705.47) less the OTDR average Link Loss
(LL) (Clause 705.42) shall not exceed 1.0dB. Results for all fibre shall be calculated
and recorded.
4
If the 1.0dB limit is exceeded for any fibre then a more
comprehensive evaluation of the individual pre-terminated connector at both
ends will need to be undertaken to determine the high loss (i.e. investigate the
launch conditions of each pre-terminated connector using OTDR in high
resolution mode.
