methods at locations shown on the construction drawings. The splice
insertion loss shall be less than 0.1 dB mean, (0.3 dB max) when measured
in accordance with EIA EIA/TIA-455-59 using an Optical Time Domain
Reflectometer (OTDR). Splices shall be designed for a return loss of 40.0
db max for single mode fiber when tested in accordance with EIA
TIA/EIA-455-107A.
2.3
FIBER OPTIC ENCLOSURES
Provide metallic enclosures for fiber optic data transmission equipment.
NEMA 250, type 4 enclosure. Enclosures shall protect the spliced fibers
from moisture and physical damage. Splice closure shall provide strain
relief for the cable and the fibers at splice points. Provide full
documentation citing conformance to structural parameters.
2.4
FIBER OPTIC TERMINATIONS AND CONNECTORS
FO connectors shall comply with EIA TIA/EIA-4750000-C and EIA TIA/EIA-604-3A.
2.5
FIBER OPTIC PATHWAY SYSTEM
Provide an FO pathway system including raceway conduit, duct system, and
maintenance manholes and handholes as shown on the drawings. Pathway
materials shall comply with EIA TIA/EIA-569-A, and the following commercial
standards for construction materials, NEMA RN 1 (PVC), NEMA TC 2 (PVC),
NEMA TC 3 (PVC), NEMA TC 6 & 8, and NEMA TC 9.
2.5.1
Conduit
Conduit as specified in Section 16302N, "Underground Transmission and
Distribution."
2.6
FACTORY FO QUALITY CONTROL
Conduct factory quality tests of FO media as required by EIA
TIA/EIA-472D000-A.
2.7
PREPARATION FOR DELIVERY
Ship media on reels in [____] ft [____] m lengths. Provide 2 meters 6 1/2
feet pigtails on each end of media accessible for testing. Reel drum shall
comply with manufacturers recommended bend radius for the media. Wind
media on reel so that unreeling can be done without kinking the media.
Attach a permanent waterproof label with indelible text on reel showing the
length, media type, bandwidth, attenuation, and date of manufacture.
2.8
FACTORY REEL TEST
Test 100 percent OTDR test of FO media at the factory prior to shipment in
accordance with EIA TIA/EIA-568-B.1 and EIA TIA/EIA-568-B.3. Use EIA
TIA/EIA-526-7 for single mode fiber and EIA TIA/EIA-526-14A Method B for
multi mode fiber measurements. Calibrate OTDR to show anomalies of 0.2 dB
minimum. Provide digitized or photographic traces to the Contracting
Officer.
