CITY OF SANTA ANA <br /> SPECIFICATIONS <br /> PROJECT NO.: 25-6030 <br /> TRAFFIC SIGNAL INSTALLATION AT SEGERSTROM AVENUE AND ROSEWOOD <br /> AVENUE <br /> to-end attenuation of the completed cable plant shall not exceed 8 dB from the <br /> termination point of the fiber to the City of Santa Ana Traffic Management Center. <br /> A minimum of 15 feet of slack shall be maintained on either side of any splice <br /> enclosure. <br /> Following installation of the cable in duct,all duct entrances in cabinets,pull boxes <br /> and vaults shall be sealed with duct sealing compound to prevent the ingress of <br /> moisture, foreign materials and rodents. <br /> 3. Splicing <br /> All fiber optic splices shall use the fusion method. The mean bi-directional splice <br /> loss of any splice shall not exceed 0.15 dB. <br /> The termination splices shall connect the fiber optic cable span ends with pigtails. <br /> The termination splices shall be placed in a splice tray. The individual fibers shall <br /> be looped one full turn within the splice tray to avoid bending losses. A 2-inch <br /> minimum bending radius shall be maintained during installation and after final <br /> assembly in the optical fiber splice tray. Each fiber shall be individually restrained <br /> in the splice tray. The optic fibers in buffer tubes and the placement of the optical <br /> fibers in the splice tray shall be such that there is no discernable tensile force on the <br /> optical fiber. <br /> All splices shall be protected with a thermal shrink sleeve or approved equivalent. <br /> All fibers shall be labeled in the splice tray with permanent vinyl markers. Pigtail <br /> ends shall also be labeled to identify the destination of the fiber. <br /> 4. Field Splice Closures <br /> Where splicing is required inside the pull box or splice vault, the Contractor is <br /> responsible for supplying the splice closure and all accessories including bond <br /> connectors and proper end plates to provide splices as recommended by the <br /> manufacturer. Unless noted otherwise, splice closure shall be Corning Splice <br /> Closure part number SCF-6C22-01-72. All splicing shall be done by the <br /> Contractor, the City will supply necessary splice detail information or splicing <br /> diagram. <br /> 5. Connectors <br /> The fiber optic connectors shall be the ceramic ferrule SC type for single mode <br /> applications. <br /> All fiber optic connectors shall be the 2.5 mm SC connector ferrule type with <br /> Zirconia Ceramic material with a PC (Physical Contact)pre-radiused tip. <br /> 79 <br />
