3.03 INSTALLATION
A. Installation of fiber cable shall be by a trained installer.
1. All fiber, if not installed inside cable tray, shall be attached to the building structure
with conduit clamps or supports a minimum of every 5 feet.
2. Fiber shall be continuous from end to end, no splices are allowed unless specifically
noted. Single mode pigtails spliced at each end of the fiber are allowed.
3. At each termination point of the fiber, the Contractor shall provide a service coil
consisting of a minimum of 30 feet of fiber cable. This coil shall be stored on the wall
in a stowage ring, Leviton No. 48900-OFR.
4. Contractor shall adhere to all manufacturer’s recommended pull tensions during
installation.
5. As part of the as-built drawings, provide the actual footage of each fiber cable
installed. Mark this on the drawings.
6. Any fiber strands that do not pass a sufficient signal light signal will be identified as
noncompliant, and the Engineer has the right to order the complete replacement of
the fiber cable by the Contractor.
7. Where fiber cable passes vertically through a building, the fiber cable shall be
supported against the wall or from the ceiling a minimum of every 5 feet.
8. Do not exceed recommended bend radius of fiber cable during or after installation.
B. Fiber patch panels shall be located at the top of the relay rack or cabinet at which they are
installed.
1. Provide patch panels as described on the contract drawings or additional panels as
required to terminate all fiber strands of all fiber cables.
2. Install fiber panels in the top of the rack, and install them in the rack closest to the
wall.
3. If a splice shelf is required for splicing of singlemode fibers, install the shelf directly
below the associated patch panel.
4. Route fiber cable into side of the panel. If the cable has single and multimode fibers,
route the subgrouped singlemode fibers to the splice shelf below.
5. The sheath of the fiber cable shall extend to the side of the panel. Individual fibers or
subgroups shall not be seen outside of the panel, except for the single mode bundles.
6. Fibers shall be installed in the adapter packs in color code order. For vertical
mounted 6 pack adapters, top to bottom then left to right. In panels where the
couplers are horizontally mounted, left to right for each 6 pack, then top to bottom.
Contact the Engineer with any questions.
7. All individual fiber strands shall be neatly installed in the back of the panel after
termination. Provide a minimum of 4 feet of spare fiber in the back of each panel. This
spare shall be coiled in a Figure 8.
8. All fibers shall be neat and orderly.
9. Label the fiber cable just outside of the fiber panel with a yellow fiber optic cable
label, Panduit No. PST-FO.
10. Secure the fiber to the entrance of the patch panel with tie wraps.
11. After installation and termination of the fiber cable, install labels on the patch panel
showing what strand each connector is connected to, and where the overall fiber
cable is terminated at the other end.
12. Attach a self-adhesive clear plastic sleeve to the inside of the plexiglas cover of the
panel. Slide in a laser printed label showing all information about the fiber cable.
C. Splicing of fiber shall be completed with a fusion splicer.
1. Each strand shall be thoroughly cleaned and all coverings shall be removed prior to
splicing
a. All connectors shall be SC connections
2. To cleave the fiber, use the method and equipment recommended by the
manufacturer of the fusion splicer that will be used.
