Telecommunication contractor must follow manufacturer's recommended installation <br />procedures. <br /> <br />C.4 Overall Requirements <br /> <br />1. IBM and its subcontractors will secure rights-of-way and pennits for this project. The ; '. <br />District will provide assistance as required to obtain rights-of-way and permits. IBM will work <br />on behalf of the District, but it is the District's responsibility to pay for all permits and rights-of- <br />way. <br />2. IBM and its subcontractors will obtain city, county, and state approvals needed for, <br />installation. <br />3. Subcontractors hired by IBM will abide by the requirements of this document.. <br />4. Installations will adhere to NEC, Rural Electric Code, and NE Safety Code. <br />s. Installations will meet city, county, and state requirements for crossing of all sidewalks and <br />streets. <br />6. IBM and its subcontractors will be responsible for repairs/restorations to streets, sidewalks, <br />grass areas, etc. which must be trenched or otherwise disturbed in the process of installation. <br />Prior to construction, IBM and its subcontractors will obtain an agreement with the property <br />owner for conditions for restoration. ' <br />7. The general intent is to minimize the number of splices used in the installation. : <br />8. Outside plant cabling will be terminated within 50 feet of entering a building. <br />9. Any cable that is gel-filled will be properly sealed and tested at building entrance. <br /> <br />C.5 Specific Requirements <br /> <br />1. At each building, a maintenance loop of fiber 10 to IS feet in length will be installed. <br />2. The vendor will provide manufacturer's test results representative of the installed fiber optic <br />cabling. <br />3. OTDR tests will be performed on installed fiber and those test results will be included in the <br />Fiber Optic Installation Summary. <br />4. All fibers among buildings will be sealed, tested, and connectorized. <br />S. Single mode fibers shall terminate on "se" connectors. <br />6. Multimode fibers shall terminate on "ST" connectors. <br />7. All splices will be the fusion type with heat-shrink proctection. <br /> <br />C.6 Testing and Acceptance <br /> <br />C.6.1 Testing <br /> <br />1. Two basic tests are performed to test the optical fiber links. One is the OTDR test, which is <br />performed during pre-installation, installation and acceptance testing of the fiber links. The <br />second is the Link Loss Test, which is performed during acceptance testing. <br /> <br />IBM Global Services &: La Porte ISO <br /> <br />peA 01 Seplember 30,1998 <br /> <br />Page 27 ofJ2 <br />
