Building Riser Specifications

A twisted pair riser cable and a fiber-optic riser (in inner-duct) shall be installed from the Service Entrance and Termination room to each Telecommunications Room and the Equipment Room:

The minimum specifications for this riser system are as follows:

• Copper Cable Riser: A minimum quantity, to be specified by ITS, Category 6 riser cable shall be installed from the Service Entrance and Termination Room to each Telecommunication Room.
• Copper Cable Testing & Records: The cable installer will provide three (3) sets of each test record report to ITS. The following electrical tests records shall be provided by the contractor on all feeder copper cables:
• Continuity test on all pairs, (test for opens)
• Test for crosses and shorts, on all pairs
• Test for loss at 1004hz, on all pairs
• Test for noise metallic and noise to ground, sampling can be used
• Test for insulation resistance, sampling can be used
• Fiber-optic Cable Riser: A minimum fiber-optic riser consisting of 6 strands of 50/125 micron multi-mode and 6 strands single-mode cable(s) will be installed from the Service Entrance and Termination Room to each Telecommunications Room.
• The fiber-optic riser cables shall be terminated at the Service Entrance and Termination Room in LIU’s installed in the corresponding rack.
• The multimode and single mode fibers shall be terminated in different LIU’s.
• In each Telecommunications Room two wall-mounted LIU’s shall be installed, one for each type of fiber.
• Terminate the fibers as follows:
• Single Mode Fiber, Simplex SC (Blue)
• Multimode 62.5 micron (legacy fiber), Duplex SC (Beige)
• Multimode 50 micron, Duplex LC (beige)
• There shall be 15 feet of slack looped in the LIU to facilitate future re-terminations.
• Acceptable Materials and Parts for Fiber-optic Cabling:
• Building to building interconnections will require 12 strands of single-mode and 12 strands of 50/125 micron multi-mode fiber to be installed.  All underground cable that is installed in conduit must be waterproof, and any standard cable must be installed in inner duct.  However, armored fiber-optic cable does not require inner duct. All part numbers provided below are from Corning Products.  It is acceptable to use a composite type fiber-optic cable when available.
• 50/125 micron fiber:
• Standard, Corning Part #012CS4-14131A20
• Armored, Corning Part #012CW5-14150A20
• Single Mode:
• Standard, Corning Part #012RS4-14101A20
• Armored, Corning Part  #012RW5-14101A20
• Interior Fiber (6 strands each of single-mode and 50/125 micron multimode fiber) for installation between floors within buildings - All part numbers are non-plenum and should be changed as needed based on required building and other construction or electrical codes.
• 50/125 micron fiber:
• Standard, Corning Part #006C81-31131-24
• Armored, Corning Part #006C81-31131A1
• Single Mode fiber:
• Standard, Corning Part #006R81-31131-24
• Armored, Corning Part #006R81-31131
• Rack Mount Termination with SC type connectors, Corning Part #CCH-01U or larger if required
• Wall Mount Termination with SC type connectors, Corning Part #WCH-02P or larger if required
• Cable Trays - Cabofil Inc., EZTray, or Chatsworth or equivalent

Grounding & Lightning Protection

Each Service Entrance and Termination Room, Equipment Room and the

Telecommunications Room shall have a bus bar installed and bonded to ground as per the requirements of Telecommunications Industry Association standard ANSI/TIA/EIA-607

Grounding and Bonding Standard are as follows:

• Ground Wires to other Telecommunication Rooms/Closets: An insulated copper ground wire shall be run from the Service Entrance and Termination Room bus bar to the Equipment Room bus bar and the ground bus bar in each Telecommunications Room. This ground wire shall be sized based on the cable size of the main electrical feed.
• Multiple Risers: If there is more than one closet riser in a building, each closet riser shall have the same ground system installed as stated in the previous paragraph.
• Ground Bus: The ground bus for the Service Entrance and Termination Room, Equipment Room, and each Telecommunications Room shall be a SQUARE D GROUND BAR KIT Cat. #PK23GTA or equivalent. If this ground conductor passes through metal conduit or metal enclosures greater than three feet in length, each end of the conduit or enclosure shall be bonded to the ground conductor by approved means.
• Grounding Plan: Each grounding plan shall be tested using a Two-Point Test Method, and the ohmic value shall be less then 0.1 ohm to be considered to have an adequate bonding between the two reference points.

POWER

The standard electrical outlet is a four-plex electrical outlet. The circuit shall be a dedicated 20 amp circuit, surge protected, with no shared neutral.
