- 1). Use existing pull string to pull a rope into the existing entrance conduit into the building. Attach rope to cable pulling eye. Begin pulling the fiber cable through the entrance conduit into the building. Regular black sheath cable cannot go more than 50 feet into the building as stated by the National Electric Code. For those cables with a metallic sheath, the cable sheath must also be grounded at the entrance room.
- 2). Choose and place a listed riser fiber cable inside the building. Indoor riser fiber is usually yellow for single mode fiber or orange for multimode fiber. Most buildings have riser sleeves or conduits from the main entrance room to the above floors. If the riser cable must go up multiple floors, it is easier to take the reel of cable up to the designated floor and drop the cable down as needed. Most reel equipment used to move the cable reel has a braking system to allow more control over lowering the cable. Once the cable is in position, it is secured to the wall on each riser closet using cable clamps.
- 3). Locate the path from the riser closet to the destination room on that floor. If the path is through the ceiling, the cable will have to either be pulled through customer-provided conduit or inner-duct, or it will be laid in the ceiling on J hooks provided by the customer. Use existing pull string to pull a small rope into the existing conduit or inner-duct. Attach rope to the cable and begin pulling the fiber cable through the conduit over to the next room.
- 4). Terminate the fibers in the room on a fiber shelf also called an OTE, or optical termination equipment. At the entrance room, use a fiber welder to splice each fiber of the entrance cable to the riser cable.
