Perform OTDR and end to end tests of all installed media. Conduct tests onsingle mode fiber in accordance with TIA-526-7 for single mode fiber andEIA TIA/EIA-526-14A for multi mode fiber.1.6 DELIVERY, STORAGE, AND HANDLINGShip media to job site on factory reels or in factory cartons. Radius ofthe reel drum shall not be smaller than the minimum bend radius recommendedby the manufacturer for the media. Wind cable on the reel so thatunwinding can be done without kinking the cable. Two meters of cable ateach end of the reel must be readily accessible for testing. Provide apermanent label on each reel showing length, media, identification number,and date of manufacture. Provide water resistant label and ink on thelabels. Apply end seals to each end of the media after testing and beforeterminating to prevent moisture from entering the cable while stored at thejob site. Reels with cable shall be suitable for outside storageconditions when temperature ranges from minus 40 degrees C to plus 65degrees C, with relative humidity from zero to 100 percent. Equipment,other than FO media, delivered and placed in storage shall be stored withprotection from weather, humidity and temperature variation, dirt and dust,or other contaminants.Exercise care in handling materials during construction. Contractor shallensure that the buried cable is fed through the plow into the ground atzero tension. Do not allow tension to develop in the cable.Whenever the plow is stopped, sufficient cable shall be unreeled to guardagainst sudden jerks when the plow is started.Exercise caution to ensure that the plow is not backed up while the bladeis in the ground. Cable can be severely damaged by the plow backing upeven a slight amount. During the plowing operation, the plow may strike aburied object or rock that would stop the equipment and necessitate removalof the plow from the ground. When this occurs, remove the plow carefullywithout backing up. When it is necessary to back the plow, uncover thecable a sufficient distance back from the plow for inspection by theContracting Officer to determine if there is any damage. Immediatelyreport any damage to the Contracting Officer. Repair or replace damages asdirected by the Contracting Officer.1.7 RELATED REQUIREMENTS**************************************************************************NOTE: Coordinate with Sections 33 71 02.00 20UNDERGROUND TRANSMISSION AND DISTRIBUTION, andSection 26 05 33 DOCKSIDE POWER CONNECTION STATIONS.For LANTNAVFACENGCOM projects, use SeL-16303NUNDERGROUND ELECTRICAL WORK in lieu of Section33 71 02.00 20 UNDERGROUND ELECTRICAL DISTRIBUTION.**************************************************************************Section 26 00 00.00 20 BASIC ELECTRICAL MATERIALS AND METHODS applies tothis section with additions and modifications specified herein.SECTION 27 13 23.00 40 Page 12
PART 2PRODUCTS2.1 FIBER OPTIC CABLE DESIGN2.1.1 Fiber Optic Media TypesFO media shall meet all performance requirements of TIA-568-C.1, TIA-568-C.3and the physical requirements of ICEA S-87-640 and TIA/EIA-598.**************************************************************************Note: Designer shall specify requirements for FiberOptic media from the following selections:Fiber Optic Media Type:(single mode) (multi mode) (hybrid)Fiber Count: [12][24][48][ ][216]Media Optic Characteristics:Fiber core diameter: [50]mmf [62.5]mmf or [ ]smfBandwidth 850nm mHz/km: [500]50 u m [160] 62.5 u mBandwidth 1300nm mHz/km: [500]50 u m [500]62.5 u mAttenuation 850nm dB: [2.5]50 u m [3.0]62.5 u mAttenuation 1300nm dB: [0.8]50 u m [0.7]62.5 u mBending Radius mm: [30]50 u m [30]62.6 u m [30]smf**************************************************************************2.1.1.1 Multi Mode Fiber MediaProvide FO media with outer sheath jacket,[ strength member,] ripcords,water blocking material,[ optional steel shield,] core tube, and corefibers as installed in a permanent underground pathway system as shown onthe construction drawings. FO media shall have an all glass, graded indexmaterial with a nominal core diameter of [62.5][____] microns. Provide acladding material for the fiber which is compatible with the core. Mediatransmission window shall be centered at 850 and 1300 nanometerwavelengths, attenuation at 1300 nanometers shall be less than [2.0][____]dB per kilometer. Minimum bandwidth shall be 500 mHz-Km.**************************************************************************NOTE: The designer shall specify the number offiber strands. The minimum number of fiber to afacility or building shall be 12 plus 25 percentspare capacity. Designer shall specify loose tubeor tight tube design. In general gelatin filledmedia should be used unless tight tube is requiredto interface with customer terminal equipment. Theloose tube construction is more appropriate wheremedia is subject to numerous bends along the cableroute. This includes aerial and long distance runs(over one Km). Tight tube design may be used forexterior direct burial in ducts below the frostline. For Navy projects the preferred undergroundinstallation is within a pathway system compliantwith EIA/TIA-569. Direct burial installations shallcomply with EIA/TIA-590. Media for DefenseInformation System Agency (DISA) equipmentconnection shall comply with Mil-Std-188-176.**************************************************************************SECTION 27 13 23.00 40 Page 13
