T/D Cabling Design Guide
All strand loss measurements shall include connectors and shall be in units of
dB / Km and shall be at or below specified limits.
Measurements shall include return loss and shall be performed at the 850nm
and 1300nm wavelengths.
4. Acceptability
Tolerance Limits - The Contractor shall be responsible for immediate
corrections to the Cabling Distribution System that will bring it into full
compliance with these Specifications.
5. Additional Testing
The Government or authorized representative or the Contractor may, at his/her
discretion, perform tests in addition to those specified herein if there is any
reason to question the condition of the material as furnished and installed.

such times as the Government, and/or authorized representative directs, the
Contractor shall conduct an operational test for approval. The installation shall
be demonstrated to be in accordance with the requirements of this specification.
Any defects revealed shall be promptly corrected at the Contractor's expense
and the tests re-conducted.
Operational Testing is defined for the following circuit types:
Backbone Cable (CMR)- Color code compliance, labeling, Computer Room,
MDF, and T/D closets jumpers, patch cords, grounding/bonding, workmanship,
termination block layout and installation, and correct routing: T/D Closet to
telephone MDF.
Fiber Optic Cable - Labeling, patch panel connections, loss measured in dB/km,
workmanship, splice loss, connector loss, circuit length, and correct routing: T/D
Closet to the Computer Room.
6. Test Reports
The Contractor shall be responsible for recording and providing to the COTR, all
test data for review by Hines BDC Engineering. Copies of all test results are to
be submitted to the Government or authorized representative for review and
remain with the Government for their records. For all fiber optic cables, a
printout from an Optical Time Domain Reflectometer shall be provided and
correspond to a labeled fiber cable. All Category 5 UTP cable must have a hard
and a disk copy output of the test results with the WSI ID assigned.
