All category 5e circuits shall be tested using a test set that meets the Level 2 e requirements of EIA ANSI/TIA/EIA-568-b.2. Testing shall use the Permanent Link Test procedure of EIA ANSI/TIA/EIA-568-b.2. Cables, which contain failed circuits, shall be replaced and retested to verify the standard is met.

3.7 Grounding System

All grounds and bonds shall be tested for continuity according to EIA ANSI/TIA/EIA-607. Resistance to ground testing shall be accomplished on the ground electrode system in accordance with Technical Order 31.10.24, Part two, Chapter 6 and (NEC) sections 250-81, 250-83 and 250-86 and must be no less than five (5) Ohms. This standard shall apply to new and existing facilities. Test results shall be reported in hard copy format. The ground shall be labeled or tagged in accordance with EIA/TIA 606.

3.8 Fiber Optic Cables

3.8.1 All multi-mode fiber optic cable test shall be performed at the 850 nm and 1300 nm windows in both directions. All fiber optic cables shall be tested on the reels prior to installation.

3.8.2 All connectors shall be tested and the loss measured in dB; connectors shall have a loss limit that complies with ANSI/TIA/EIA-526-14A, Commercial Telecommunications Cabling Standard.

3.8.3 All fiber optic links shall be tested and the loss measured in dB/KM.

3.8.4 All fiber optic links shall be tested with a power meter. A copy of the test results shall be provided by the Contractor to the Contracting Officer (USAF) for each fiber, tested in both directions at bandwidths specified in paragraph 3.8.1 above.

3.8.5 All test results shall be documented in accordance with the Contracting Officers instructions and recorded on USAF forms provided by the Contracting Officer.

3.8.6 End to end testing is defined from the equipment end through the cross connect to the terminal end.

3.8.7 After testing is completed, all circuits shall be restored to their pre-test state (i.e. reconnected, re-terminated, etc.)

3.8.8 All fiber optic test results shall be in compliance with ANSI/TIA/EIA-568-b.1, Commercial Building Telecommunications Cabling Standard.

3.9 ACCEPTABILITY

3.9.1 Tolerance Limits

The Contractor shall be responsible for immediate corrections to the communications cabling systems that shall bring it into full compliance with these specifications.

3.10 ADDITIONAL TESTING

3.10.1 The Contracting Officer or his authorized representative or the Contractor may, at his discretion, perform tests in addition to those specified in this document, if there is any reason to question the condition of the material as furnished and installed.

3.10.2 After installation is complete, in addition to any other required testing, and at such times as the Contracting Officer or his authorized representative directs, the Contractor shall conduct an operating 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 no cost to the government and the tests re-conducted.

3.10.3 Operational Testing is defined for the following circuit types:

a. Station Cable – Color code compliance, labeling, correct pin termination at outlet location, routing, workmanship, NEXT and attenuation.

b. Backbone Cable (CMR) – Color code compliance, labeling, computer room and distribution closet jumpers, patch cords, grounding/bonding, workmanship, termination block layout and installation, and routing.

c. Fiber Optic Cable – Labeling, patch panel connections, loss measured in Db/km, workmanship, and routing.

d. Ground Cable – Labeling, connections, connectivity, workmanship, and routing.

3.11 TEST REPORTS

3.11.1 The Contractor shall be responsible for recording and providing to the Contracting Officer, all test data. Copies of all test results shall be submitted the Contracting Officer or his authorized representative for review and remain the property of the Government for their records. For all fiber optic cables, power meter test results shall be provided hard copy and correspond to a labeled fiber optic cable. All twisted pair copper cable shall have a disk copy output of the test results with the station ID assigned. All test results shall be provided in hard copy format to the Contracting Officer prior to Quality Assurance Inspection for acceptance of Premises Wire Distribution System installation.
