g. Pull Calculations

h. Bend Radius shall be shown to not exceed manufacturer recommendation both during the pull and when at rest.

i. Pull/blowing lengths -- shall be designed to not exceed 80% of the rated cable tensile strength or 600 lbs during installation whichever is less. No residual tension shall remain on the cable after installation except that due to the cable's weight in the vertical rise.

Assist points for blowing cable shall be identified.

j. If a winch or pulling machine is used during installation, a dynamometer shall be used to monitor the tension on the cable. The dynamometer shall be certified as calibrated and shall hold the peak value of the cable pull. The peak value shall be recorded and forwarded to the MBTA as part of the installation test data submittals.

C. Installation Methods – at all times the Contractor shall use the least damaging installation method to install cables in order to ensure maximum cable life and maintainability. Methods of installation shall include:

1. Use of innerduct – the Contractor shall use innerduct within ducts, conduits, and cable trays to optimize conduit usage and prevent damage to cable both in current installation and in future installations. Pneumatic couplers shall be used to take advantage of cable blowing installation methods.

2. Intermediate manholes and handholes – Fiber cables passing through intermediate manholes and handholes shall be racked and use continuous innerduct.

3. Cable Blowing – the preferred method of installing fiber cable in ducts with PVC innerduct shall be blowing.

4. Cable Pulling - the preferred method of installing fiber cable in ducts with textile innerduct shall be with a pull rope.

5. Cable Laying – in cable trough the Contractor shall use cable laying techniques to reduce stress.

Cables shall not be pulled through cable trays.

6. Cable Pulling – Due to the potential for stress damage the Contractor shall continuously monitor stress placed upon the cable with dynamometer or approved equivalent test equipment. The maximum pull tension for the cable shall not be exceeded. The maximum recommended load value for long term application shall not be exceeded after the cable has been placed.

Dynamometer or approved equivalent test equipment calibration records and data from the monitoring shall be submitted with the cable test results.

7. Slack Cable – every cable length greater than 1000 feet shall have one (1) 60-foot slack coil of cable placed at either end. A minimum of one (1) 30-foot slack coil shall be placed at either end of every fiber cable.

8. Slack Enclosure- Fiber Optic Slack loops shall be placed outside the rack/cabinet on a NEMA 4X slack storage enclosure that can accommodate up to 100ft of FO cable. Enclosures shall be wall or pole mounted and shall include document pocket, and lockable “L” pad lock handle (or hasp and stable with lever type, quick release fastener around door perimeter). Door stiffeners shall be provided as required.

F60PS01 FIBER OPTIC CABLE SYSTEM MBTA N.A.

2026 16749P - 15

9. Bend Radius – fiber cable shall not be bent to a smaller radius than its minimum installation radius value. After pulling tension is removed, cable may be bent to a radius no smaller than the long-term application bend radius for the cable.

Figure 1

a. Plastic cable ties shall not be used for banding or securing fiber optic cables/patch cords.

Hook and loop cable ties shall be used for banding or securing fiber optic cables and patch cords.

b. All fiber optic cabling in racks or cable trays shall be secured using hook and loop cable wraps.

c. All 90-degree corners used to route and support fiber cables on cable racks shall be equipped with corner brackets to maintain a greater than minimum bend radius.

10. Damage Protection

a. Where cables leave conduits, the ends of the conduit shall be fitted with end bells to prevent damage to the cable.

b. In other installations where sharp edges are encountered, the Contractor shall supply protection from friction damage.

c. In manholes, where splices or slack is present, slack, and/or splice case shall be secured to wall of manhole on an approved cable racking device.

F60PS01 FIBER OPTIC CABLE SYSTEM MBTA N.A.

2026 16749P - 16

11. Penetrations -- All cable entrance openings shall be sealed with either a compression type fitting or pliable sealing compound after the cable is in place. Sealing compound shall be used to seal the area around cable where the cable emerges from the end of a conduit or pipe. Sealing compounds for rooms, houses, walls, or other partitions shall be fire retardant per ASTM E-814.

All spare conduits shall be sealed or plugged in an approved manner. Cable openings within the substation floors and/or walls shall be sealed with an approved fire sealant.
