23、Page 1 SECTIONAL SPECIFICATION FOR SPLICE CLOSURES FOR PRESSURIZED AERIAL, BURIED AND UNDERGROUND FIBER OPTIC CABLES (From EIA Standards Proposal No. 1825, formulated under the cognizance of the P0-6,3 8ubcbmmittee on Fibex Optic Interconnecting Devices . ) 1.0 SCOPE 1.1 Obj ect The object of this S
24、pecification is to prescribe preferred ratings and characteristics for pressurized aerial, buried or underground fiber optic splice closures; select from EIA-5150i300, “Generic Specification for Optical Fiber and Cable Splices,“ the appropriate quality assessment procedures, tests, and measuring met
25、hods; and to give general performance This requirements for this type splice closure. Sectional Specification must be used in conjunction with a fiber splice sectional to specify a complete optical cable splice. The Specification addresses those requirements necessary to provide external protection
26、for an optical fiber splice, but does not cover the properties of a fiber-to-fiber splice. 1.2 Closure Types This Sectional Specification identifies the characteristics of pressure-tight fiber optic cable splice closures designed for use with fiber optic cables in underground, buried, and aerial tel
27、ecommunications applications. Moisture access into the cable closure will generally be excluded by means of a positive gas pressure system, normally not exceeding 70 kilopascals (10 pounds per square inch). 1.3 Closure Classifications Splice closures are classified according to the configuration in
28、which cables may enter the ends of the closure as follows: 1.3.1 Straight Splice Closure: Closures that provide openings for only one cable to enter each end of the closure. EIA 5L5BOOO 87 W 3234b00 0073033 b W EIA-515B000 Page 2 1.3.2 Branch Splice Closures: Closures that provide openings for two o
29、r more cables to enter one or both ends of the closure. 1.3.3 Butt Splice Closures: Closures that provide openings such that two or more cables enter one end of the closure and no cable enters the other end of the closure. 2.0 APPLICABLE DOCUMENTS ASTM D56-82 Test Methods for Flash Point by Tag Clos

31、d Date Code Marking (April 1981) 3.0 DESIGN CRITERIA 3.1 precedence The requirements for an optical cable splice closure shall be as specified in this Sectional Specification and in the accompanying Generic and Detail Specifications. In the event that the requirements of this Specification conflict
32、with the requirements of the Generic or Detail Specification, the order of precedence shall be Sectional and Detail. 3.2 Ma te r i a i s Materials shall be compatible with the requirements as specified in the Detail Specification. 3.3 Physical Characteristics The physical dimensions, weight, color a
33、nd finish shall be specified in the Detail Specification. EIA 5358000 7 3234600 0073034 = EIA-515BgUfl Page 3 3 04 Interchangeability Sufficient dimensioning and material data must be provided in the Detail Specification to assure interchangeability without selection of parts or without departure fr
34、om the specified equipment performance. 3.5 Bonding and Grounding Closures intended for use with cables having metallic elements such as shields, vapor barriers and strength members, shall meet the requirements of para. 3.5.1 through para. 3.5.4, unless otherwise specified in the Detail Specificatio
35、n. Bonding and grounding requirements shall not apply to closures intended only for use with fully non-metallic cables unless otherwise specified in the Detail Specification. 3.5.1 Shield and Strength Member Continuity The splice closure shall be designed to permit establishing cable shield and stre
36、ngth member electrical continuity at the beginning of the splicing operation. Continuity must not be disrupted by susbsequent re-entries into the splice closure. Installation of the bonding device should require minimal cable sheath preparation. 3.5.2 Bonding Clamps Bonding clamps must be able to wi
37、thstand a current flow conducted to it by the cable shield from a power contact fault. The conductive path shall have a current carrying capacity equal to or greater than that of the cable sheath being joined. 3.5.3 External Ground The closure must have provisions for the installation to the cable s
38、hield and metallic strength members of an external ground conductor equivalent to a No. 6 AWG copper wire unless otherwise specified in the Detail Specification. Aerial closures must. ensure an electrical bond between the cable shield, strength and the support strand. EIA 5L5BOOO 87 m 323Yb00 007303
39、5 T m EIA-515B000 Page 4 3.5.4 Insulating Joints When specified in the Detail Specification, the closure must be capable of providing an insulating joint (electrical isolation) between the closure and the cable shield or streng th members . Insulating joints may require additional pieces of hardware
40、 and are often used in connection with corrosion protection. 3.6 Closure Housing 3.6.1 Material Compatibility The closure housing must be compatible with all materials used in bonding and ground devices, and chemicals and sealants which the closure would contact under normal use. 3.6.2 Cor ros ion P
41、rotect ion The use of additional external wraps, coatings, etc., shall not be required for corrosion protection unless otherwise specified in the Detail Specification. 3.6.3 Resistance to Sunlight The closure housing and any other exposed parts of closures intended for aerial applications must be ma
42、de of materials which will resist deterioration when exposed to the unltra-violet rays of the sun. 3.6.4 Non-Metallic Closure Materials Non-metallic closure materials used for closure housings and any other exposed parts of the closure shall be materials which are resistant to deterioration or stres
43、s cracking when subjected to petroleum products or other chemicals to which it might be subjected in normal telecommunications applications. 3.7 Re-Entry The closure should be re-enterable without destruction of the housing unless such destruction is economically justified. If reusable, the closure
44、components should l- EIA 5L5B000 87 m 3234b00 O073036 L m EIA-5 15B000 Page 5 be immediately reusable, without factory refurbishing and with minimum field rehabilitation work. When a number of units are being re-entered, factory refurbishing is allowed when economically justified. 3.8 Fiber Bend Rad
45、ius Controller The splice closure shall have provisions for controlling the radius at which fibers are stored in the closure. The bend radius of the storage feature shall be specified in the Detail Specification. 3.9 Fiber Splice Retention The splice closure shall have provisions for holding the fib
46、er splices and any excess fiber in an orderly and accessible manner. 3.10 Cable Clamping and Sealing The attachment of cable clamping and sealing hardware shall not cause an increase in fiber splice or cable loss when . measured in accordance with FOTP-20, (EIA-455-20) “Measurement of Change in Opti
47、cal Transmittance,“ unless otherwise specified in the Detail Specification. All metallic cable clamping shall not be subject to corrosion. 3.11 Splice Isolation The splice closure shall isolate the fiber splice from stress when a tensile load is applied to the cables. No axial or lateral force on th
48、e cable shall be transmitted to the fiber splice. 4.0 PERFORMANCE AND PHYSICAL INTEGRITY CRITERIA The splice closure shall meet all optical, mechanical and environmental integrity criteria as specified in the Detail Specification when the required test procedures are followed. Mechanical and environ
49、mental criteria shall be chosen from the tests listed below. Sample selection and preparation, applicabilty of the performance criteria, and test sequencing requirements shall be as specified in Section 5.0. 4.1 Visual and Mechanical The splice closure components shall be kept in their shipping container(s) up to time of inspection and assembly to avoid loss, damage, or contamination of the part. The closure components shall meet the specified design and dimensional requirements when visually examined, using equipment capable of measuring to the specified tolerances. The physical
