【国外标准】 Standard Practice for Operation and Maintenance of Sewers with Optical Fiber Systems

5.1 This is intended to outline O&M issues that require discussion and mutual agreement by both the optical fiber cable owner and sewer pipeline operator. The purpose is developing sufficient written procedures and practices to allow optical fiber systems to coexist as a secondary use within a sewer. To the extent that sewers are primarily for conveying flow, it is the responsibility of the optical fiber cable owner to accommodate sewer O&M practices and develop optical fiber system O&M procedures that will not material impact the sewer’s primary function.5.2 Since the practice of integrating sewers and optical fiber systems is an emerging activity, this practice will help establish guidelines for its rapid and safe deployment, ensuring that the installed facilities are operable as intended on a long-term basis.1.1 This practice applies to the operation and maintenance of sewers with a subsequent installation of optical fiber cable in accordance with Practice F2303.1.2 This practice applies to gravity flow storm sewers, sanitary sewers, and combined sewers.1.3 This practice does not apply to force mains, siphons, or other pressurized sewers.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
