      Use wireways on verticals of relay racks to accommodate the fiber cable on the backside and the fiber patch cords to the front of racks.
      Jumper or patch cords are to be used to connect different fibers together for continuation of service. Do not wrap a jumper completely around a routing guide or other type bracket. When using routing guides on a relay rack always use the rear portion of the guides to hold vertical jumper runs and the front portion of the guides to hold horizontal jumpers. Always use the front routing guide to enter or leave a housing.
      There should be a minimum of 20 ft. slack left in a terminal room, mounted in a circular configuration on fire rated plywood (3/4 in.). This is necessary in the event of a fiber break.
      All fiber strands shall be terminated in accordance with the industry standard color codes.
      Label all fiber cable and all fiber strands at termination locations. Telecommunications Center will provide fiber cable nomenclature.
      Test all strands using an optical time domain reflectometer (OTDR) and optical loss test sets (OLTS). Fiber cable runs less than 100 meters in length shall be tested with an approved light meter. Provide computer readable test results of each fiber strand to Telecommunications Center. See Section 6. for additional testing information.
