pair identifier for cables in accordance with EIA ANSI/TIA/EIA-606A and as
specified. The labeling format shall be identified and a complete record
shall be provided to the Government with the final documentation. Each
cable shall be identified with type of signal being carried and termination
points.
3.1.9
Enclosure Sizing and Cable
Termination enclosures shall be sized to accommodate the FO equipment to be
installed. Sizing shall include sufficient space for service loops to be
provided and to accommodate a neat, workmanlike layout of equipment and the
bend radii of fibers and cables terminated inside the enclosure.
3.1.10
Enclosure Penetrations
Enclosure penetrations shall be from the bottom and shall be sealed with
rubber silicone sealant to preclude the entry of water. Conduits rising
from underground shall be internally sealed.
3.2
TESTING
**************************************************************************
NOTE: Insert the title of the appropriate system
specification (such as UMCS, IDS, ESS or CCTV).
**************************************************************************
3.2.1
General
The Contractor shall provide personnel, equipment, instrumentation, and
supplies necessary to perform testing.
3.3.2
Contractor's Field Test
The Contractor shall verify the complete operation of the data transmission
system in conjunction with field testing associated with systems supported
by the fiber optic data transmission system as specified in Section [_____]
prior to formal acceptance testing. Field tests shall include a flux
density test. These tests shall be performed on each link and repeated
from the opposite end of each link.
3.2.2.1
Optical Time Domain Reflectometer Tests
Optical time domain reflectometer tests shall be performed using the FO
test procedures of EIA ANSI/EIA/TIA-455-59A. An optical time domain
reflectometer test shall be performed on all fibers of the FO cable on the
reel prior to installation. The optical time domain reflectometer shall be
calibrated to show anomalies of 0.2 dB as a minimum. Photographs of the
traces shall be furnished to the Government. An optical time domain
reflectometer test shall be performed on all fibers of the FO cable after
it is installed. The optical time domain reflectometer shall be calibrated
to show anomalies of 0.2 dB as a minimum. If the optical time domain
reflectometer test results show anomalies greater than 1 dB, the FO cable
segment is unacceptable to the Government. The unsatisfactory segments of
cable shall be replaced with a new segment of cable. The new segment of
cable shall then be tested to demonstrate acceptability. Photographs of
the traces shall be furnished to the Government for each link.
