705.27 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 must be upgraded

Conduit Upgrading

3. Once all sections of the proposed haul have been proven the hauling tensions and lay off points ,if required, shall be determined

Lay off Points

4. Pressure roping shall be used in preference to hand rodding, to minimise the possibility of intertwining of cables during hauling.

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.

5. If a fibre fails the OTDR Link Loss after a number of re-measurements, 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).

Test Failure

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.

Test Wavelengths

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.

Irregularity Locations

3. Any point loss that exceeds the above criteria shall be rectified with the fibre subsequently retested.

Check Failure

705.44 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.

Excessive Splice Loss

705.45 LSPM INSTERTION LOSS

1. 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:

Maximum Insertion Loss

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

Where;

a) IL = Maximum allowable Insertion Loss in dB,

b) L = optical section link Length in km,

c) N = Number of splices including pre-terminated connector, and

d) C = total number of through Connectors.

4. If a fibre exceeds the acceptance criteria then the insertion loss value shall be appropriately marked (e.g. circled, highlighted, etc.).

Excessive Insertion Loss

705.46 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.

705.47 COMMISSIONING ACCEPTANCE TEST RESULTS

1. All OTDR Fibre test results shall be recorded and submitted in both original Trace Format and pdf. Original Trace Format in soft copy (electronically) with original Trace Format reader and all tested Fibres Trace results, pdf’s in both hard and soft copies (electronically).
