935.3.05 Construction

Secure from the cable manufacturer the construction and installation procedures to be used on the project.

Produce a detailed construction and installation procedure (SOP) covering all aspects of the construction and

installation process for each and all specific cable to be used on this project. Submit the SOP to the Engineer for

review and approval.

Follow all appropriate OSHA and industry standards related to safety when working in manholes or

underground vaults and when handling optical fibers.

Install all fiber optic cable according to the manufacturer’s recommended procedures and these

specifications.

Do not exceed the maximum recommended pulling tension during installation as specified by the cable

manufacturer.

Do not violate the minimum recommended bend radius during installation as specified by the cable

manufacturer. Unless the manufacturer’s recommendations are more stringent, use the following guidelines

for minimum bend radius:

20 X Cable Diameter Short Term - During Installation

10 X Cable Diameter Long Term - Installed

Before the installation begins, carefully inspect the cable reels for imperfections such as nails that might cause

damage to the cable as it is unreeled.

Take all necessary precautions to protect reeled cable from vandals or other sources of possible damage

while unattended. Any damage to the cable sections may require replacement of the entire section. 1889

Whenever unreeled cable is placed on the pavement or surface above a manhole, provide means of

preventing vehicular or pedestrian traffic through the area in accordance with Section 150 of the

specifications.

Use the "figure-eight" cable lay configuration to prevent kinking or twisting when the cable is unreeled or

backfed. Do not coil fiber optic cable in a continuous direction except for lengths of 100 ft. (30 m) or less.

When "figure-eighting" cable, exercise care to relieve pressure on the cable at the crossover of the eight. This

may be done by placing cardboard shims at the crossover or by forming a second "figure-eight".

Keep the cable continuous throughout the pull. Cable breaks are allowed only at designated splice points.

Where messenger cable is required, as shown in the plans, lash aerial fiber optic cable to a steel strand wire

messenger cable of the size specified in the plans that conforms to Georgia Department of Transportation

specification 915.02.

Where a cable ends without termination in a fiber optic closure, seal the end of the cable by re-using a cable

end cap shipped with a cable reel, or use a cap that is size-matched to the cable to be sealed. Clean the end

of the cable. Partly fill the cap with a waterproof silicone adhesive sealant and press the cap fully onto the

cable end, rotating the cap to fully encapsulate the cable end with the sealant in the cap. Apply a full sealant

bead between the end of the cap and the cable jacket.

At designated intervals throughout the cable plant, pull and store excess cable for slack for future terminations or

splicing.

Properly store all cable to minimize susceptibility to damage. Maintain proper bend radius, both short and long

term, during cable storage.

Communication and Pull Boxes: Store the excess or slack cable in the pull box or communication box in

accordance with the plans details.

Hub/TMC/TCC: Properly store the cable in cable troughs and plenum applications which meet NEC requirements.

Aerial Installations: Store the excess or slack cable at storage loops in a “bow tie” configuration on the messenger

strand using two fiber optic snowshoes (aerial fiber cable storage brackets) that maintain the proper bend radius in

the fiber cable. Install one fiber optic snowshoe for drop cable and trunk cable storage at aerial splice closures to

maintain the proper bend radius in the fiber optic cable.

or "core misalignment."

Ensure that the maximum splice loss for any fusion splice does not exceed 0.10 dB.

Ensure the maximum splice loss for mechanical splices does not exceed 0.70 dB. As noted in this specification,

mechanical splicing is only allowed when approved by the Engineer for temporary applications.

Test all completed and assembled pre-terminated FDCs at the point of manufacture and provide two copies of the

manufacturer test documentation. Test each connecterized fiber in the pre-terminated FDC to demonstrate

compliance with all requirements for cables and connectors as detailed in other subsections of these

specifications. Include in the test documentation the location station number where the FDC is to be installed, the

serial number of the pre-terminated FDC, the drop cable footage markings at each end of the drop cable, and the

total drop cable distance. Place one copy of the manufacturer test documentation in the equipment cabinet

drawer where the pre-terminated FDC is installed, and submit the other copy to the Engineer.
