T/D Cabling Design Guide
2. Material Submittals
Within 10 days from date of Notice-To-Proceed, the Contractor shall provide
manufacturer's product data. The data may be illustrations, standard schedules,
performance charts, instructions, brochures, and diagrams, or other information
furnished to illustrate a product, material or intended for some portion of the
work. Physical examples may be requested that represent materials, equipment,
or workmanship and establish standards by which the work may be judged.
3. Workmanship
NEC approved installation practices must be adhered to, in order to prevent
personnel injury and damage to equipment. The cable network shall be installed
in accordance with ANSI/EIA/TIA standards to prevent mechanical damage and
EMI.
A. UTP Cable Terminations
Six inch excess cable lengths shall be provided at all UTP cable
terminations. The amount of untwisting in a pair as a result of termination to
connecting hardware shall be no greater than 0.5 inches.
B. Fiber Optic Backbone: Terminations & Bend Radius
Twenty foot service loops shall be provided at all FO cable terminations. The
loops shall include "inner-duct' and shall be located neatly in interstitial space
directly adjacent to the patch panels.
Fiber optic manufacturer's
recommended bend radius shall not be exceeded.
C. Temporary Cabling
If temporary cable and wire pairs are used, they shall be installed so as to
present no pedestrian safety hazard. The Contractor shall be responsible for
all work associated with temporary installations and for removal when no
longer necessary.
4. CDS Labeling & Documentation
The Contractor shall devise a cable labeling and records management system in
accordance with ANSI/TIA/EIA 606. The system shall include a numbering
scheme for the Government provided cable pathways (trays, conduits, etc.) and
shall label all cables at each exposed end with a unique identifier to ease
individual cable tracing.
Using this system, the Contractor shall establish, maintain, and provide to the
Government, a 3.5 inch computer diskette containing a Microsoft Excel
formatted data base and provide a hard copy of cable and wire records. The
data base shall identify each circuit by Work Station Interface designation, origin
and destination, and routing through Government provided pathways.
