<br />e <br /> <br />e <br /> <br />2. When crossing unimproved roads, streets and alleys that may later be paved or hard surfaced, <br />the cable should be placed at a depth that retains sufficient cover following pennanent grading of <br />the road. <br /> <br />C.3.15 Splice Points <br /> <br />1. In order to reach a splicing vehicle, each splice point should include a minimum of 33 ft. of <br />cable on both cable ends. <br />. <br />2. At hand holes cable slack should be placed horizontally in the hole. In the case of a b~ried <br />splice point, the slack should be coiled and buried vertically (in line with the cable route). <br />3. At specific intervals, up to 328 feet of excess slack may be buried/placed within a splice <br />point. <br />4. This excess slack can provide added cable for restorations or reconfigurations without <br />digging up large parts of the cable system. <br />5. The splice closures should meet the following requirements: <br />· Suitable for either butt or through cable entry configurations <br />· Moisture-tight sealing arrangements. <br />· Re-enterable for system expansions and repair. <br />· No stress placed on finished splices within trays. <br />6. Indoor splice centers must be wall-mount with optional rack mount and support various <br />splicing methods. The following requirements have to be met: <br />· Individual tray access. <br />· Multiple cable entrances to accommodate custom design specifications. <br />· Front panel easily removed for full access. <br />· Cable strain-relief provisions. <br />· Labels provided for administrative documentation. <br /> <br />C.3.16 Underground Enclosures <br /> <br />Enclosures and covers shall be rated for no less than 8,000 lbs. over a 10" x I 0" area. Material <br />compressive strength should be no less than 11,000 psi. Covers shaH have a minimum <br />coefficient of friction of 0.5. Boxes shall be stackable for extra depth. Underground Enclosures <br />with splice tray and cable retainers shall be used as outside splice centers. At hand holes (17" x <br />30" boxes), 50 feet cable slack should be placed horizontally in the hole. <br /> <br />C.3.17 Buried Warning Tape <br /> <br />The use of a warning tape is required. A bright orange (preferably "ULCC" orange) warning <br />tape with a minimum width of three inches must be buried approximately one foot below the <br />existing grade. As a minimum, the tape should be marked "WARNING-OPTICAL CABLE". <br /> <br />C.3.18 Marker Signs <br />IBM Global Sen.jees & La Porte ISO <br /> <br />peA 01 September 30.1998 <br /> <br />Page ~4 of32 <br />
